Each model will be described in detail below.
[0076] At least some of the vision correction surgery-related models (M) can be trained and / or generated using the same learning device. For example, the surgery suitability prediction model (M10) and the laser surgery suitability prediction model (M11) can be trained and / or generated using the same learning device. Alternatively, at least some of the vision correction surgery-related models (M) can be trained and / or generated using different learning devices.
[0077] At least some of the vision correction surgery-related models (M) may be executed by the same prediction device. For example, the surgery suitability prediction model (M10) and the laser surgery suitability prediction model (M11) may be executed by the same prediction device. Alternatively, at least some of the vision correction surgery-related models (M) may be executed by different prediction devices.
[0078] The vision correction surgery-related model according to an embodiment may be trained and / or implemented using an artificial intelligence model / algorithm and is not limited by its training and / or implementation method. For example, the vision correction surgery-related model may be trained and / or implemented using various machine-running models / algorithms and deep-running models / algorithms, such as a classification algorithm, a regression algorithm, supervised learning, unsupervised learning, reinforcement learning, a support vector machine, a decision tree, a random forest, LASSO, AdaBoost, XGBoost, an artificial neural network, etc.
[0079] According to an embodiment, a vision correction surgery-related model may be trained and / or generated through a training phase. The vision correction surgery-related model trained and / or generated through the training phase may calculate a prediction result through a prediction phase.
[0080] 6 is a diagram illustrating a learning step (S10) and a prediction step (S30) of a vision correction surgery-related model according to an embodiment. Referring to FIG. 6, the learning step (S10) may include a learning data acquisition step (S110) and a model learning step (S150).
[0081] The learning data acquisition step (S110) may be a step of acquiring learning data, which is data for the learning device to learn and / or generate a vision correction surgery-related model.
[0082] The model training step (S150) may be a step of training and / or generating a vision correction surgery-related model. In the model training step (S150), a training device may train and / or generate the model based on training data acquired in the training data acquisition step. For example, model parameters constituting the vision correction surgery-related model may be changed in the model training step (S150). The accuracy of the model may be improved by changing the parameters.
[0083] The vision corrective surgery-related model may be trained based on vision corrective surgery-related information of patients who have undergone vision corrective surgery. For example, the model may be trained based on at least one of pre-vision examination data of patients who have undergone vision corrective surgery, surgical parameters of the vision corrective surgery performed on the patients, and post-vision examination data of the patients.
[0084] Referring to FIG. 6, the prediction step (S30) may include an input data acquisition step (S310) and a model execution step (S350).
[0085] The input data acquisition step (S310) may be a step of acquiring input data that is used by the prediction device to calculate a prediction result using a vision correction surgery-related model.
[0086] The model execution step (S350) may be a step of calculating a prediction result based on the vision correction surgery-related model learned and / or generated in the learning step (S10) and the input data. For example, the prediction device may output a prediction result based on the input data and model parameters obtained from the learning device.
[0087] The input data for the vision correction surgery-related model may include all information acquired for the subject, or may include at least a portion of the information acquired for the subject, and the input data may be the same or different for different vision correction surgery-related models.
[0088] The prediction results of the vision correction surgery-related model may vary depending on the training data, or the accuracy of the vision correction surgery-related model may vary depending on the training data.
[0089] The predicted result may vary depending on the type of true value included in the training data. For example, the predicted result may vary depending on whether the true value takes into account the subjective will of the subject. Here, the subjective will of the subject may include preferences, such as whether or not the subject prefers a particular vision correction surgery, and ability to pay, such as whether or not the subject will pay a certain amount of money for the vision correction surgery. When the subjective will of the subject is not taken into account, the predicted result may be a medically suggested result. On the other hand, when the subjective will of the subject is taken into account, the predicted result may be the same as or different from the medically suggested result.
[0090] If the first training data and the second training data are acquired at different hospitals, or acquired from different doctors, or acquired at different times, the first model trained and / or generated based on the first training data and the second model trained and / or generated based on the second training data may be different from each other. As a result, the first prediction result output by the first model and the second prediction result output by the second model may be different from each other. Furthermore, the accuracies of the first model and the second model may be different from each other.
[0091] However, the same vision correction surgery-related model can be trained and / or generated even if the training data is different, or the same prediction results can be calculated using vision correction surgery-related models trained and / or generated using different training data.
[0092] The training data, input data, and prediction results (hereinafter referred to as "input / output data") may include variables such as medical examination data and surgical parameters. The medical examination data and surgical parameters may be expressed in various ways, such as numbers, letters, images, etc., and are not limited to these representation methods. Furthermore, the images are not limited to their dimensions, such as two-dimensional or three-dimensional images.
[0093] The medical examination data may include interview data, which is information obtained by questioning without using equipment or examination, eyeball characteristic data, which is information about the eyeball obtained through equipment or examination, and genetic information.
[0094] The interview data may include the same variables as the subject's gender, age, race, living environment such as area of residence, demographic characteristics such as occupation, income, educational background, education, and family size, medical and family history such as high blood pressure and diabetes, and preferences for vision correction surgery.
[0095] The ocular characteristic data may include any type of information about the eye, for example, the ocular characteristic data may include variables such as visual acuity, intraocular pressure, and / or retinal test results.
[0096] The ocular characteristic data may include information about the physical shape of the eye. In one example, the ocular characteristic data may include variables such as white-to-white (WTW) distance, angle-to-angle (ATA) distance, internal anterior chamber depth (ACD), sulcus-to-sulcus (STS) distance, and pupil size. In another example, the ocular characteristic data may include information about the shape of the cornea, such as corneal shape factors and corneal topography images. Here, the corneal shape factors are numerical values that indicate the physical shape of the cornea, and may include variables such as the index of surface variance (ISV), index of vertical asymmetry (IVA), keratoconus index (KI), central keratoconus index (CKI), minimum radius of curvature (Rmin), index of height asymmetry (IHA), index of height decentration (IHD), and central cornea thickness. The corneal topography image is an image relating to the shape of the cornea, and may include a corneal topography diagram, an anterior corneal curvature image, a posterior corneal curvature image, a corneal thickness diagram, and the like.
[0097] The ocular characteristic data may be acquired using, but is not limited to, tomography, topography, optical coherence tomography (OCT), ultrasound biomicroscopy (UBM) equipment such as Pentacam, CASIA2, AL-Scan, and OQAS. Information that can be acquired through the above equipment and similar equipment and information derived therefrom may be included in the ocular characteristic data.
[0098] Genetic information can be obtained through genetic testing, etc. Genetic information can be used to determine whether a subject is suitable for vision correction surgery or to predict side effects after vision correction surgery. For example, genetic information can be used to predict whether a subject will develop corneal abnormalities.
[0099] Surgical parameters are variables related to the execution of vision correction surgery, and may include variables that can be changed during vision correction surgery, such as the type of vision correction surgery, such as LASIK, LASEK, small incision lenticular extraction, lens insertion, standard vision correction surgery, custom vision correction surgery, etc., corneal flap thickness, corneal flap diameter, flap side cut angle, corneal cutting profile, ocular suction time, surgical range (optic zone), hinge position, hinge angle, and hinge structure, such as hinge width.
[0100] Standard vision correction surgery may refer to vision correction surgery to correct low-order aberrations, and custom vision correction surgery may refer to vision correction surgery to correct low-order and high-order aberrations.
[0101] The types of surgical parameters considered by patients undergoing standard vision correction surgery and custom vision correction surgery may differ. For example, the types of surgical parameters considered by patients undergoing custom vision correction surgery may include the types of surgical parameters considered by patients undergoing standard vision correction surgery.
[0102] The number of surgical parameters that change depending on the patient in standard vision corrective surgery may be different from the number in custom vision corrective surgery. Standard vision corrective surgery and custom vision corrective surgery may be distinguished by the number of surgical parameters that change depending on the patient. The number of surgical parameters that change depending on the patient (hereinafter referred to as the "reference value") that distinguishes standard vision corrective surgery from custom vision corrective surgery may be a predetermined value. For example, if the number of surgical parameters that change depending on the patient is equal to or greater than the reference value, the surgery may be custom vision corrective surgery, and if it is less than the reference value, the surgery may be standard vision corrective surgery.
[0103] Standard and custom vision correction surgeries may vary depending on the hospital, doctor, and / or time period performing the vision correction surgery. For example, base prices may vary depending on the hospital, doctor, and / or time period.
[0104] Custom vision correction surgery can include ContourVision surgery and Wavefront surgery.
[0105] Custom vision correction surgery can improve the quality of vision compared to standard vision correction surgery. Vision quality is a comprehensive term that refers to the quality of vision, and can be determined based on not only visual acuity measured using an eye chart, low-order aberrations, and high-order aberrations, but also clarity of vision, light blur, contrast sensitivity, night vision, glare, double vision, afterimages, and other inconveniences.
[0106] The input / output data may include not only measured values that can be acquired / measured through interviews, medical examinations, etc., but also predicted values that can be calculated through vision correction surgery-related models, etc. For example, the ocular characteristic data may include not only measured values of the subject's ocular characteristic data acquired / measured through pre-vision surgery examinations, etc., but also predicted values of the subject's ocular characteristic data after vision correction surgery, calculated through vision correction surgery-related models, etc.
[0107] The input / output data may be preprocessed before being input to the vision correction surgery-related model. For example, a learning device may preprocess the acquired input / output data before using it to learn the vision correction surgery-related model. Alternatively, a prediction device may preprocess the acquired input / output data before inputting it to the vision correction surgery-related model to calculate a prediction result.
[0108] Preprocessing should be interpreted broadly to include any changes made to input or output data and is not limited to the examples disclosed herein.
[0109] The preprocessing may include selecting at least some of the variables that include the input / output data, such as feature selection. For example, the preprocessing may include t-test, Gini index, information gain, relief, DistAUC, signal to noise, MRMR, Fisher score, Laplacian score, SPEC, etc.
[0110] Preprocessing may include generating new variables from at least some of the variables containing the input and output data, such as feature extraction. For example, preprocessing may include principle component analysis, linear discriminant analysis, canonical correlation analysis, singular value decomposition, ISOMAP, locally linear embedding, etc. For other examples, preprocessing may include generating spectra from numerical values or generating images from numerical values.
[0111] Preprocessing may include methods for handling missing values, such as missing value handling, when variables required by a vision correction surgery-related model (or a learning device and / or a predictor) are not included in the input / output data. For example, preprocessing may include handling missing values using the mean or mode of the corresponding variable.
[0112] The accuracy of a vision correction surgery-related model can be improved through preprocessing. In one example, the accuracy of a vision correction surgery-related model that includes a feature selection step may be better than the accuracy of a model that does not include the feature selection step. In another example, the accuracy of a vision correction surgery-related model that generates an image from numerical values and calculates a predicted result based on the image may be better than the accuracy of a vision correction surgery-related model that calculates a predicted result based on the numerical values.
[0113] 7 is a diagram illustrating preprocessing of input and output data according to one embodiment. Referring to FIG. 7, input and output data may be preprocessed (S500) and then input to a vision correction surgery-related model. The vision correction surgery-related model may calculate a prediction result based on the preprocessed input and output data (S700).
[0114] The vision correction surgery-related model can include multiple sub-models, each of which can calculate a predicted outcome based on input data.
[0115] A vision correction surgery related model may include sub-models linked in series and / or parallel, such as an ensemble model.
[0116] The vision correction surgery-related model may include a plurality of sub-models connected in series. Here, "sub-models connected in series" may include calculating the output of at least one sub-model based on the output of at least one sub-model, such as when the output of a first sub-model becomes the input of a second sub-model. Alternatively, "sub-models connected in series" may include passing through a plurality of sub-models in order to obtain a predicted result from input data through the vision correction surgery-related model.
[0117] 8 is a diagram illustrating a vision correction surgery-related model (M) including serially connected sub-models (M1, M2) according to one embodiment. Referring to FIG. 8, the vision correction surgery-related model (M) may include a first sub-model (M1) and a second sub-model (M2) connected in series. The first sub-model (M1) calculates an output based on input / output data, and the second sub-model (M2) calculates a prediction result based on the output of the first sub-model (M1).
[0118] The vision correction surgery-related model may include multiple sub-models connected in parallel, where the sub-models being connected in parallel may include the output of a sub-model not affecting the output of another sub-model, such as the output of a first sub-model not depending on the output of a second sub-model.
[0119] The inputs of the parallel-connected sub-models may be the same, or the inputs of the parallel-connected sub-models may be different. For example, the first medical data input to the first sub-model may be different from the second medical data input to the second sub-model.
[0120] The first medical data may include at least some other variables than the second medical data, for example, the first medical data may include a vision correction surgery preference, but the second medical data may not include a vision correction surgery preference.
[0121] The first medical examination data may include the same type of variables as the second medical examination data, but the values may be different. For example, the first medical examination data and the second medical examination data may include corneal thickness, but the values may be different because the methods for obtaining the values are different (e.g., the corneal thickness is measured using different devices).
[0122] The vision correction surgery-related model may include an output sub-model that calculates an output based on the outputs of multiple sub-models connected in parallel. In one example, if the outputs of the multiple sub-models are the same, the output sub-model may provide the same output. In another example, if the outputs of the multiple sub-models are different, the output sub-model may output a result that takes into account the outputs of the multiple sub-models at a certain ratio, or may provide a specific output from among the multiple outputs. In yet another example, the output sub-model may output a result generated based on the outputs of the multiple sub-models.
[0123] 9 is a diagram illustrating a vision correction surgery-related model (M) including sub-models (M1, M2) connected in parallel according to one embodiment. Referring to FIG. 9, the vision correction surgery-related model (M) may include a first sub-model (M1) and a second sub-model (M2) connected in parallel. The vision correction surgery-related model (M) may also include an output sub-model (M3) that calculates an output based on the outputs of the first sub-model (M1) and the second sub-model (M2). The first sub-model (M1) and the second sub-model (M2) calculate a first output and a second output, respectively, based on input / output data, and the output sub-model (M3) may calculate a prediction result based on the first output and the second output.
[0124] An example of a vision surgery related model that includes sub-models connected in parallel may include, but is not limited to, an ensemble.
[0125] The following describes specific examples of vision correction surgery-related models.
[0126] The surgery suitability prediction model can predict whether or not a subject is suitable for vision correction surgery. The surgery suitability prediction model can predict whether or not a subject is suitable for surgery based on input data.
[0127] The appropriateness of vision correction surgery means medical appropriateness. Accordingly, the input data of the surgery appropriateness prediction model does not need to include the subject's preference for vision correction surgery. Alternatively, the surgery appropriateness prediction model can predict the appropriateness of surgery without considering the subject's preference for vision correction surgery.
[0128] The suitability for surgery may include whether surgery is possible and whether surgery is necessary. In one example, the surgery suitability prediction model may determine a subject who has good vision and does not need surgery as a surgery unsuitable subject. In another example, the surgery suitability prediction model may determine a subject whose vision cannot be improved by vision correction surgery as a surgery unsuitable subject.
[0129] The suitability of surgery can be output as surgery suitable / unsuitable, or the suitability of surgery can be output as a numerical value or visualized.
[0130] The laser surgery eligibility prediction model can predict whether a subject is eligible for laser vision correction surgery. Here, laser vision correction surgery refers to surgery that corrects vision through corneal ablation using a laser. The laser surgery eligibility prediction model can predict whether a subject is eligible for laser surgery based on input data.
[0131] The feasibility of laser-based vision correction surgery means medical feasibility. Accordingly, the input data of the laser surgery feasibility prediction model does not need to include the subject's preference for vision correction surgery. Alternatively, the laser surgery feasibility prediction model can predict the feasibility of laser surgery without considering the subject's preference for vision correction surgery.
[0132] The feasibility of laser surgery can be output as either possible or impossible, or the feasibility of laser surgery can be output as a numerical value or visualized.
[0133] The corneal shape factor prediction model can predict the corneal shape factor of a subject after vision correction surgery. The model can predict one or more corneal shape factors. The corneal shape factor prediction model can predict the corneal shape factor based on input data.
[0134] Input data for the corneal shape factor prediction model can include surgical parameters. For example, the input data can include the type of surgery as a surgical parameter. The model can predict corneal shape factors corresponding to the input surgical parameters. In one example, if the input data includes LASIK, LASEK, and small-incision lenticular extraction as surgical parameters, the output of the model can include a predicted corneal shape factor after LASIK, a predicted corneal shape factor after LASEK, and a predicted corneal shape factor after small-incision lenticular extraction. In another example, if the input data includes standard vision correction surgery and custom vision correction surgery as surgical parameters, the output of the model can include a predicted corneal shape factor after standard vision correction surgery and a predicted corneal shape factor after custom vision correction surgery.
[0135] The corneal shape factor prediction model can predict corneal shape factors corresponding to predetermined surgical parameters, regardless of whether its input data includes surgical parameters. For example, if the model is trained to predict corneal shape factors after standard vision corrective surgery and after custom vision corrective surgery, the model can output predicted corneal shape factors after standard vision corrective surgery and predicted corneal shape factors after custom vision corrective surgery even if the input data of the model does not include surgical parameters.
[0136] Table 1 shows the output of a corneal shape factor prediction model according to one embodiment. Referring to Table 1, the corneal shape factor prediction model can output the IHD, ISV, and IVA values of a subject. The corneal shape factor prediction model can also include the subject's IHD, ISV, and IVA measurement values obtained before vision correction surgery, predicted IHD, ISV, and IVA values expected after standard vision correction surgery, and predicted IHD, ISV, and IVA values expected after custom vision correction surgery.
[0137] JPEG0007741914000001.jpg34170
[0138] The custom vision corrective surgery need prediction model can predict whether a subject needs custom vision corrective surgery. The custom vision corrective surgery need prediction model can predict the need for custom vision corrective surgery based on input data.
[0139] The custom vision corrective surgery need prediction model can predict the need for custom vision corrective surgery without taking into account the subject's vision corrective surgery preferences. Alternatively, the custom vision corrective surgery need prediction model can predict the need for custom vision corrective surgery while taking into account the subject's vision corrective surgery preferences. The output of the custom vision corrective surgery need prediction model can change depending on whether or not the subject's vision corrective surgery preferences are taken into account.
[0140] The custom vision correction surgery necessity prediction model can determine whether a subject needs custom vision correction surgery based on ocular characteristic data such as corneal shape factors and corneal topography images.
[0141] The custom vision corrective surgery need prediction model can determine the need for custom vision corrective surgery based on the absolute numerical value of the corneal shape factor. For example, the custom vision corrective surgery need prediction model can predict that a subject needs custom vision corrective surgery if the corneal shape factor is outside a certain range.
[0142] The custom vision corrective surgery need prediction model can determine the need for custom vision corrective surgery based on the relative values of the corneal shape factors. For example, the custom vision corrective surgery need prediction model can determine the need for custom vision corrective surgery by comparing the difference between the corneal shape factors after standard vision corrective surgery and the corneal shape factors after custom vision corrective surgery.
[0143] The vision corrective surgery recommendation model can recommend a vision corrective surgery for a subject. In one example, the model can output a single vision corrective surgery. In another example, the model can output multiple vision corrective surgeries. In yet another example, the model can output multiple vision corrective surgeries along with information regarding their priority.
[0144] The vision correction surgery suggestion model can suggest vision correction surgery based on input data.
[0145] The vision corrective surgery corresponding to the subject means a vision corrective surgery calculated by the vision corrective surgery proposal model without considering the subject's vision corrective surgery preference. Alternatively, the vision corrective surgery corresponding to the subject means a vision corrective surgery calculated by the vision corrective surgery proposal model while considering the subject's vision corrective surgery preference. The output of the vision corrective surgery proposal model can change depending on whether the subject's vision corrective surgery preference is considered.
[0146] An output of the vision correction surgery recommendation model may be a consideration of custom vision correction surgery needs, such as standard LASIK, custom LASIK, standard LASEK, custom LASEK, standard small incision lenticular extraction, custom small incision lenticular extraction, etc.
[0147] Alternatively, the output of the vision correction surgery suggestion model may be that the need for custom vision correction surgery was not considered. For example, the output may be that the need for custom vision correction surgery was not considered, such as LASIK, LASEK, small incision lenticular extraction, lens implantation, etc.
[0148] The vision corrective surgery recommendation model can recommend a vision corrective surgery based on the quality of vision after the vision corrective surgery. For example, the model can recommend a vision corrective surgery based on predicted vision after the vision corrective surgery corresponding to a plurality of vision corrective surgeries.
[0149] Table 2 is the output of a vision correction surgery suggestion model according to one embodiment. Referring to Table 2, the vision correction surgery suggestion model can output LASIK, LASEK, and small incision lenticular extraction surgeries along with information on priority, such as suitability. In the case of Table 2, the value corresponding to small incision lenticular extraction is greater than the values corresponding to LASIK and LASEK, which means that the vision correction surgery suggestion model recommends small incision lenticular extraction as the first priority. In addition to the method shown in Table 2, information on priority can be output in various ways to indicate priority.
[0150] JPEG0007741914000002.jpg37170
[0151] The surgical parameter suggestion model can suggest surgical parameters. The model can suggest one or more surgical parameters. The surgical parameter suggestion model can suggest surgical parameters based on input data.
[0152] Input data for the surgical parameter suggestion model may include data in the form of an image. Here, the image may be an image acquired through measurement and / or inspection using a device along with a corneal topography. Alternatively, the image may be an image generated through interpolation, extrapolation, artificial intelligence, etc. based on measured values. For example, the image may be an image generated from corneal shape factors.
[0153] The surgical results of vision correction surgery performed based on surgical parameters suggested by the surgical parameter suggestion model based on an image may be better than the surgical results of vision correction surgery performed based on surgical parameters suggested based on numerical values. For example, the surgical results of vision correction surgery performed based on surgical parameters suggested by the model based on corneal topography images may be better than the surgical results of vision correction surgery performed based on surgical parameters suggested based on corneal shape factors such as IHD, ISV, and IVA. Here, the surgical results refer to the quality of post-operative vision. Alternatively, the surgical results refer to the shape of the post-operative cornea.
[0154] The visual acuity prediction model can predict a subject's visual acuity after vision correction surgery. The visual acuity prediction model can output a visual acuity prediction value based on input data. The model can predict one or more visual acuities.
[0155] Input data for the visual acuity prediction model may include surgical parameters. For example, the input data may include the type of surgery as a surgical parameter. The model may predict visual acuity corresponding to the input surgical parameters. In one example, if the input data includes LASIK, LASEK, and small-incision lenticular extraction as surgical parameters, the output of the model may include predicted visual acuity after LASIK, predicted visual acuity after LASEK, and predicted visual acuity after small-incision lenticular extraction. In another example, if the input data includes standard vision correction surgery and custom vision correction surgery as surgical parameters, the output of the model may include predicted visual acuity after standard vision correction surgery and predicted visual acuity after custom vision correction surgery.
[0156] A visual acuity prediction model can predict visual acuity corresponding to predetermined surgical parameters, regardless of whether its input data includes surgical parameters. For example, if the model is trained to predict visual acuity after standard vision corrective surgery and visual acuity after custom vision corrective surgery, the model can output predicted visual acuity values after standard vision corrective surgery and predicted visual acuity values after custom vision corrective surgery, even if the input data of the model does not include surgical parameters.
[0157] The visual acuity prediction model can predict visual acuity corresponding to multiple different times. For example, the model can predict visual acuity corresponding to a first time and a second time after vision correction surgery. Examples of multiple different times include, but are not limited to, one day, one week, one month, six months, and one year after vision correction surgery.
[0158] The visual acuity prediction model can predict the subject's visual acuity recovery rate based on predicted visual acuity values corresponding to multiple different times. For example, the model can predict the visual acuity recovery rate based on a first time and a second time after vision correction surgery.
[0159] The predicted visual acuity image generation model can predict the visual field of a subject after vision correction surgery. The model can generate a visualized image of the quality of the subject's vision after vision correction surgery (hereinafter referred to as the "predicted visual acuity image"). By outputting the predicted visual acuity image, vision correction surgery can be more easily explained to the subject. By visualizing and outputting the visual field after vision correction surgery, the model can more clearly understand the expected results after vision correction surgery, which can be useful in selecting vision correction surgery.
[0160] Input data for the predicted vision image generation model may include surgical parameters. For example, the input data may include the type of surgery as a surgical parameter. The model may predict a predicted vision image corresponding to the input surgical parameters. In one example, if the input data includes LASIK, LASEK, and small-incision lenticular extraction as surgical parameters, the output of the model may include a predicted vision image after LASIK, a predicted vision image after LASEK, and a predicted vision image after small-incision lenticular extraction. In another example, if the input data includes standard vision correction surgery and custom vision correction surgery as surgical parameters, the output of the model may include a predicted vision image after standard vision correction surgery and a predicted vision image after custom vision correction surgery. In yet another example, if the input data includes multiple surgical zones (optic zones), the output of the model may include multiple predicted vision images corresponding to the multiple surgical zones.
[0161] The predicted visual acuity image generation model can generate predicted visual acuity images corresponding to predetermined surgical parameters, regardless of whether its input data includes surgical parameters. For example, if the model is trained to generate predicted visual acuity images after standard vision corrective surgery and predicted visual acuity images after custom vision corrective surgery, the model can output predicted visual acuity images after standard vision corrective surgery and predicted visual acuity images after custom vision corrective surgery even if the input data of the model does not include surgical parameters.
[0162] The predicted vision image may include information on at least one of the subject's predicted vision sharpness, light blur, contrast sensitivity, night vision, glare, double vision, and afterimages after vision correction surgery. 10A and 10B are diagrams illustrating predicted visual acuity images according to an embodiment. Referring to FIG. 10A, predicted visual acuity images (I1, I2) can visualize and represent information related to the clarity of visual acuity. Referring to FIG. 10B, predicted visual acuity images (I3, I4, I5, I6) can visualize and represent information related to light blurring. Each of the multiple predicted vision images may correspond to different surgical parameters. Referring to FIG. 10a, the first predicted vision image (I1) may correspond to the clarity of vision after custom vision correction surgery, and the second predicted vision image (I2) may correspond to the clarity of vision after standard vision correction surgery. Referring to FIG. 10b, the third through sixth predicted vision images (I3-I6) may correspond to different surgical zones. For example, the surgical zone of the third predicted vision image (I3) may be larger than the surgical zones of the fourth through sixth predicted vision images (I4-I6).
[0163] According to an embodiment, the predicted visual acuity image may be generated through filtering using a filter. Here, filtering may refer to generating a filtered image by convolving an image with a filter, as a concept commonly used in the field of image processing. Examples of filters include, but are not limited to, an average filter, a weighted average filter, a low-pass filter, a Gaussian filter, a median filter, a bilateral filter, a blurring filter, a high-pass filter, an unsharp masking filter, a high-boost filter, and a sharpening filter.
[0164] 11 is a diagram illustrating a predicted visual acuity image generation model (M17) using a filter according to an embodiment. Referring to FIG. 11, the predicted visual acuity image generation model (M17) can include a first sub-model (M171) and a second sub-model (M172).
[0165] The first sub-model (M171) can calculate and / or select a filter based on input data. In one example, the input data includes predicted ocular characteristic data values after vision correction surgery of the subject, and the first sub-model (M171) can calculate and / or select a filter based on the predicted ocular characteristic data values. In another example, the input data includes measured ocular characteristic data values and surgical parameters of the subject, and the first sub-model (M171) can calculate and / or select a filter based on the measured ocular characteristic data values and the surgical parameters.
[0166] The second sub-model (M172) can generate a predicted visual acuity image based on the filter calculated and / or selected by the first sub-model (M171). For example, the second sub-model (M172) can generate a predicted visual acuity image by applying the filter to an original image. Here, the original image can be input from outside the predicted visual acuity image generation model (M17) as a base image for generating the predicted visual acuity image, or can be included in the model (M17).
[0167] The corneal topography image prediction model can predict a corneal topography image of a subject after vision correction surgery. The model can predict one or more corneal topography images. The corneal topography image prediction model can generate a corneal topography image based on input data.
[0168] Input data for the corneal topography image prediction model can include surgical parameters. For example, the input data can include the type of surgery as a surgical parameter. The model can predict corneal topography images corresponding to the input surgical parameters. In one example, if the input data includes LASIK, LASEK, and small-incision lenticular extraction as surgical parameters, the output of the model can include a post-LASIK corneal topography image, a post-LASIK corneal topography image, and a post-small-incision lenticular extraction corneal topography image. In another example, if the input data includes standard vision correction surgery and custom vision correction surgery as surgical parameters, the output of the model can include a post-standard vision correction surgery corneal topography image and a post-custom vision correction surgery corneal topography image.
[0169] The corneal topography image prediction model can generate corneal topography images corresponding to predetermined surgical parameters, regardless of whether its input data includes surgical parameters. For example, if the model is trained to generate corneal topography images of visual acuity after standard vision corrective surgery and corneal topography images of custom vision corrective surgery, the model can output corneal topography images of standard vision corrective surgery and corneal topography images of custom vision corrective surgery even if the input data of the model does not include surgical parameters.
[0170] Input data for the corneal topography image prediction model can include a corneal topography image of a subject measured before vision correction surgery. Figure 12 is a diagram illustrating a corneal topography image according to one embodiment. Referring to Figure 12, the corneal topography image prediction model (M18) can predict a corneal topography image (CI2) of a subject after vision correction surgery based on a corneal topography image (CI1) of the subject measured before vision correction surgery. Although Figure 12 illustrates only the corneal topography image (CI1) being input to the model (M18), other input data can also be input.
[0171] The prediction result calculation cause analysis model can analyze the causes of the calculation of the prediction result generated by the vision correction surgery-related model. The model can calculate the dependency of the vision correction surgery-related model on input data. Here, the dependency can include how a specific variable of the input data affects the prediction result.
[0172] The prediction result calculation cause analysis model may output a prediction result calculation cause. The model may output one or more prediction result calculation causes. For convenience of explanation, the following description will be given assuming that the prediction result calculation cause is expressed as a numerical value such as a dependency coefficient. However, the prediction result calculation cause is not limited to this and may be expressed in any manner, such as a numerical value, an image, text, or a combination thereof.
[0173] The causal analysis model for calculating a predicted outcome may output at least some of the dependency coefficients, for example, the model may output all of the calculated dependency coefficients.
[0174] The prediction result calculation cause analysis model may output the calculated dependency coefficients that fall within a certain range. For example, the model may output the calculated dependency coefficients that are greater than a predetermined value. Alternatively, the model may output the calculated dependency coefficients whose absolute values are greater than a predetermined value.
[0175] The prediction result calculation cause analysis model can output a predetermined number of dependency coefficients. For example, the model can output a predetermined number of dependency coefficients.
[0176] The causal analysis model for calculating predicted results may include an analytical model for predicting the suitability of surgery, an analytical model for predicting the suitability of laser surgery, an analytical model for predicting the cause of corneal shape factors, an analytical model for predicting the need for custom vision correction surgery, an analytical model for proposing vision correction surgery, an analytical model for proposing surgery parameters, an analytical model for predicting the cause of visual acuity, an analytical model for generating predicted vision images, and an analytical model for predicting corneal topography images. For example, the analytical model for predicting the cause of visual acuity may calculate how variables included in the input data of the visual acuity prediction model affect the visual acuity prediction model's prediction of visual acuity. Alternatively, the analytical model for predicting the cause of visual acuity may calculate the dependency of the visual acuity prediction value calculated by the visual acuity prediction model on the input data of the visual acuity prediction model.
[0177] The cause analysis model for calculating the predicted outcome may include at least a portion of a vision correction surgery-related model. For example, the cause analysis model for visual acuity prediction may include a visual acuity prediction model.
[0178] 13 is a diagram illustrating a predicted outcome calculation cause analysis model (M19) including a vision correction surgery-related model (M192) according to one embodiment. Referring to FIG. 27, the predicted outcome calculation cause analysis model (M19) can include an input data disturbance model (M191), a vision correction surgery-related model (M192), and a predicted outcome analysis model (M193).
[0179] The input data perturbation model (M191) can output perturbed input data based on input data. The model (M191) can output one or more perturbed input data. Here, perturbing the input data means changing the input data, such as changing the values of at least some variables included in the input data. For example, if the variables are numerical values, perturbation means increasing or decreasing the numerical values. Alternatively, if the variables are images, perturbation means increasing or decreasing the pixel values of at least some pixels of the image.
[0180] The vision corrective surgery-related model (M192) can output a first prediction result corresponding to the input data and a second prediction result corresponding to the disturbed input data based on input data and disturbed input data. For example, if the vision corrective surgery-related model (M192) included in the prediction result calculation cause analysis model (M19) is a visual acuity prediction model, the first prediction result and the second prediction result may be different visual acuity prediction values. Furthermore, if there are multiple disturbed input data, the model can output multiple prediction results corresponding to the multiple disturbed input data.
[0181] The prediction result analysis model (M193) can output the cause of calculation of the prediction result based on the prediction result. For example, the model (M193) can calculate the cause of calculation of the prediction result based on the difference between a first prediction result calculated from unperturbed input data and a second prediction result calculated from perturbed input data. Specifically, the model (M193) can calculate the dependency of the first prediction result on the first variable based on the difference between the first prediction result and a second prediction result calculated from input data perturbed by a first variable.
[0182] FIG. 14 is a diagram illustrating causes of calculation of a prediction result according to one embodiment, specifically, causes of visual acuity prediction. Referring to FIG. 14, the causes of calculation of a prediction result may be displayed using numerical values and images. The same characters as Cornea_Back_Rmin (V1), Astigmatism (V2), Mono (V3), Nearsightedness (V4), Op_flag (V5), and Pupil_Dia (V6) shown in FIG. 14 may correspond to variables included in the input data. The values 5.95 (N1), -0.5 (N2), 0 (N3), -1.37 (N4), 2 (N5), 3.1 (N6), etc., shown corresponding to the characters may correspond to the numerical values of variables included in the input data.
[0183] The dependency of the prediction result on variables may be visualized. For example, the dependency may be indicated by the length, color, direction, etc. of the arrow. Referring to FIG. 14, the length of the arrow may correspond to the absolute value of the dependency coefficient. The direction and color of the arrow may correspond to the sign of the dependency coefficient. In FIG. 14, the visual acuity prediction value (OV) is 1.18, and it can be interpreted that Cornea_Back_Rmin (V1), Astigmatism (V2), Mono (V3), and Nearsightedness (V4) have a positive effect on the visual acuity prediction value, and Op_flag (V5) and Pupul_Dia (V6) have a negative effect on the visual acuity prediction value.
[0184] Examples of the cause analysis model for calculating the predicted results include, but are not limited to, LIME (Local Interpretable Model-agnostic Explanations).
[0185] Vision correction surgery related models can be combined with one another. The models can be combined by at least one of serial connection and parallel connection.

[0224] Below, examples of recommended methods for vision correction surgery will be examined.
[0225] The vision corrective surgery recommendation method may be implemented using one or more vision corrective surgery-related models. When the method is implemented using a plurality of vision corrective surgery-related models, whether or not at least one vision corrective surgery-related model is executed may depend on the prediction result of at least one other vision corrective surgery-related model. For example, whether or not a second vision corrective surgery-related model is executed may depend on the prediction result of a first vision corrective surgery-related model.
[0226] Each step of the vision correction surgery recommendation method described below can be performed by a prediction device.
[0227] FIG. 35 is a diagram relating to a first embodiment of a method for recommending vision correction surgery according to one embodiment.
[0228] Referring to FIG. 35, a method for recommending vision correction surgery according to one embodiment may include a step of acquiring medical examination data of a subject (S1100), a step of predicting whether the subject is suitable for vision correction surgery (S1200), a step of predicting whether the subject is suitable for vision correction surgery using a laser (S1300), a step of calculating a predicted corneal shape factor value of the subject (S1400), and a step of proposing vision correction surgery suitable for the subject (S1500).
[0229] The step of acquiring medical data of the subject (S1100) may include a computing device acquiring the medical data including interview data and ocular characteristic data measurements.
[0230] The step of predicting whether the subject is suitable for vision corrective surgery (S1200) may include inputting a first group of data obtained from the subject's medical examination data into a first prediction model to predict whether the subject is suitable for vision corrective surgery. The first prediction model may be a surgery suitability prediction model. The surgery suitability prediction model can predict whether the subject is suitable for vision corrective surgery based on the first group of data.
[0231] The step of predicting whether the subject is a candidate for laser-based vision correction surgery (S1300) may include inputting a second group of data acquired from the subject's medical examination data into a second prediction model to predict whether the subject is a candidate for laser-based vision correction surgery. Whether or not the step (S1300) is performed may depend on whether the subject is a candidate for vision correction surgery. For example, the step (S1300) may be performed if the subject is a candidate for vision correction surgery. The second prediction model may be a laser surgery candidate prediction model. The laser surgery candidate prediction model can predict whether the subject is a candidate for laser surgery based on the second group of data.
[0232] The step of calculating the predicted corneal shape factor of the subject (S1400) may include inputting a third group of data obtained from the subject's medical examination data into a third prediction model to calculate the predicted corneal shape factor after standard vision correction surgery and the predicted corneal shape factor after custom vision correction surgery of the subject. Whether or not the step (S1400) is performed may depend on whether the subject is eligible for vision correction surgery using a laser. For example, the step (S1400) may be performed if the subject is eligible for vision correction surgery using a laser. The third prediction model may be a corneal shape factor prediction model. The third prediction model may predict the corneal shape factor based on the third group of data. In this case, the need for custom vision correction surgery may be determined based on the corneal shape factor.
[0233] The step of proposing a vision corrective surgery for the subject (S1500) may include inputting a fourth group of data acquired from the subject's medical examination data into a fourth prediction model to propose a vision corrective surgery for the subject. Whether or not the step (S1500) is performed may depend on whether the subject is eligible for vision corrective surgery using a laser. For example, the step (S1500) may be performed if the subject is eligible for vision corrective surgery using a laser. The fourth prediction model may be trained based on at least one of medical examination data of multiple subjects who have undergone vision corrective surgery, the vision corrective surgery corresponding to the multiple subjects, and the visual acuity of the multiple subjects after the vision corrective surgery. The fourth prediction model may be a vision corrective surgery proposing model. The fourth prediction model may propose a vision corrective surgery for the subject based on the fourth group of data.
[0234] Referring to FIG. 35 , the vision correction surgery may be one that does not take into account the predicted corneal shape factor and / or the need for custom vision correction surgery. For example, the vision correction surgery may include LASIK, LASEK, and small-incision lenticular extraction. Furthermore, because lens insertion is not always possible even when laser vision correction surgery is possible, the vision correction surgery may include lens insertion. This also applies to other embodiments and implementations of this specification. In this case, the vision correction surgery that takes into account the predicted corneal shape factor and / or the need for custom vision correction surgery can be determined by the doctor and / or consultant. For example, the doctor and / or consultant can determine the vision correction surgery that takes into account the need for custom vision correction surgery, such as standard LASIK, standard LASEK, standard small-incision lenticular extraction, custom LASIK, custom LASEK, or custom small-incision lenticular extraction, based on the predicted corneal shape factor and the vision correction surgery output by the vision correction surgery recommendation method of FIG. 35 .
[0235] FIG. 36 is a diagram relating to a second embodiment of a method for recommending vision correction surgery according to an embodiment.
[0236] Referring to FIG. 36, a method for recommending vision correction surgery according to one embodiment may include a step of acquiring medical examination data of a subject (S2100), a step of predicting whether the subject is suitable for vision correction surgery (S2200), a step of predicting whether the subject is suitable for vision correction surgery using a laser (S2300), a step of calculating a predicted corneal shape factor value of the subject (S2400), and a step of proposing vision correction surgery suitable for the subject (S2500).
[0237] The method for recommending vision correction surgery in FIG. 36 is similar to that in FIG. 35, so differences from FIG. 35 will be mainly described.
[0238] Referring to FIG. 36 , the step of proposing a vision correction surgery for the subject (S2500) may suggest a vision correction surgery based on the predicted corneal shape factor after standard vision correction surgery and the predicted corneal shape factor after custom vision correction surgery, which are calculated in the step of calculating the predicted corneal shape factor of the subject. The vision correction surgery may be performed taking into consideration the need for custom vision correction surgery. For example, the vision correction surgery may include standard LASIK, standard LASEK, standard small incision lenticular extraction, custom LASIK, custom LASEK, and custom small incision lenticular extraction. The vision correction surgery may also include lens implantation.
[0239] FIG. 37 is a diagram relating to a third embodiment of a method for recommending vision correction surgery according to an embodiment.
[0240] Referring to FIG. 37, a method for recommending vision correction surgery according to one embodiment may include a step of acquiring medical examination data of a subject (S3100), a step of predicting whether the subject is suitable for vision correction surgery (S3200), a step of predicting whether the subject is suitable for vision correction surgery using a laser (S3300), a step of predicting whether the subject needs custom vision correction surgery (S3400), and a step of proposing vision correction surgery corresponding to the subject (S3500).
[0241] The recommended method for vision correction surgery in FIG. 37 is similar to that in FIG. 35, so differences from FIG. 35 will be mainly described. Referring to FIG. 37 , the step of predicting whether the subject needs custom vision corrective surgery (S3400) may include inputting a third group of data acquired from the subject's medical examination data into a third prediction model to predict whether the subject needs custom vision corrective surgery. Whether step (S3400) is performed may depend on whether the subject is eligible for laser vision corrective surgery. For example, step (S3400) may be performed if the subject is eligible for laser vision corrective surgery. The third prediction model may be a model for predicting the need for custom vision corrective surgery. The third prediction model may predict the need for custom vision corrective surgery based on the third group of data. The step may predict the need for custom vision corrective surgery based on the subject's predicted corneal shape factor after standard vision corrective surgery and the predicted corneal shape factor after custom vision corrective surgery.
[0242] The step of predicting whether the subject needs custom vision corrective surgery (S3400) and the step of proposing corresponding vision corrective surgery to the subject (S3500) may be coupled. For example, the output of the step of proposing corresponding vision corrective surgery to the subject (S3500) may be calculated based on the output of the step of predicting whether the subject needs custom vision corrective surgery (S3400). Alternatively, the output of the step of predicting whether the subject needs custom vision corrective surgery to the subject (S3400) may be calculated based on the output of the step of proposing corresponding vision corrective surgery to the subject (S3500).
[0243] In one example, the step of proposing a vision correction surgery corresponding to the subject (S3500) may suggest a vision correction surgery based on the need for custom vision correction surgery calculated in the step of predicting whether the subject needs custom vision correction surgery (S3400). For example, the vision correction surgery may include standard LASIK, standard LASEK, standard small incision lenticular extraction, custom LASIK, custom LASEK, and custom small incision lenticular extraction. The vision correction surgery may also include lens implantation.
[0244] In another example, the step of predicting whether the subject needs custom vision corrective surgery (S3400) may output a second vision corrective surgery based on the first vision corrective surgery calculated in the step of proposing a vision corrective surgery corresponding to the subject (S3500). Here, the first vision corrective surgery may be one in which the need for custom vision corrective surgery is not taken into consideration, and the second vision corrective surgery may be one in which the need for custom vision corrective surgery is taken into consideration.
[0245] In another example, in predicting whether or not the subject needs custom vision corrective surgery (S3400), whether or not to perform the surgery may be determined based on the type of the first vision corrective surgery calculated in proposing vision corrective surgery corresponding to the subject (S3500). For example, if the first vision corrective surgery is of a first type, the custom vision corrective surgery necessity prediction model may not be executed, and if the first vision corrective surgery is of a second type, the custom vision corrective surgery necessity prediction model may be executed.
[0246] The first and second types can be distinguished by whether or not corneal ablation is performed using a laser. For example, the first type may be a non-laser vision correction surgery such as lens implantation, and the second type may be a laser vision correction surgery such as LASIK, LASEK, or small incision lenticular extraction.
[0247] The first and second types may be distinguished based on whether or not a procedure allows custom surgery. For example, the first type may be a vision correction procedure that does not allow custom surgery, and the second type may be a vision correction procedure that allows custom surgery. Here, whether or not a procedure allows custom surgery may be determined based on predetermined criteria. However, such criteria may vary depending on technological developments, hospitals, surgical equipment, the circumstances and judgment of physicians, etc. For example, if custom small-incision lenticular extraction is not available, the first type may include small-incision lenticular extraction and lens implantation, and the second type may include LASIK and LASEK. However, if custom small-incision lenticular extraction is available, the first type may include lens implantation, and the second type may include LASIK, LASEK, and small-incision lenticular extraction.
