[0068] Figure 1 This is a schematic flowchart illustrating the method for manufacturing a prosthetic eye according to an embodiment of this application. Figure 1 As shown, the method for manufacturing the prosthetic eye of this application includes the following steps S1 to S5:

[0069] Step S1: Obtain patient eye image data, which includes image data of the affected eye and image data of the healthy eye;

[0070] Step S2: Construct an initial three-dimensional data model of the prosthetic eye based on the image data of the affected eye. The initial three-dimensional data model is a simulation model with three-dimensional morphological features.

[0071] Step S3: Match the healthy eye image data with data samples in the preset prosthetic eye database, and determine the texture image data based on the similarity. The texture image data includes at least one of iris image data, pupil image data, blood vessel image data, and sclera image data.

[0072] Step S4: The texture image data is fused with the initial three-dimensional data model to obtain the target three-dimensional data model of the prosthetic eye.

[0073] Step S5: Fabricate a prosthetic eye based on the target three-dimensional data model.

[0074] In the above scheme, an initial three-dimensional data model with three-dimensional morphological features is constructed based on the patient's affected eye image data. Data samples with high similarity to the healthy eye are matched with the patient's healthy eye image data in the prosthetic eye database. The data samples are directly called as the texture image data of the prosthetic eye. The texture image data is then fused with the initial three-dimensional data model. The entire design process is simpler and more convenient, shortens the design time, and has high modeling efficiency. Furthermore, by constructing a structure with three-dimensional morphological features, the realism of the prosthetic eye is improved.

[0075] The following describes the solution in detail with reference to the embodiments and the modeling method provided in this application:

[0076] Step S1: Obtain patient eye image data, which includes image data of the affected eye and image data of the healthy eye.

[0077] In some implementations, image data of the affected eye can be obtained by taking a model of the patient's affected eye and then performing a 3D scan on the model; alternatively, a color image of the surface of the patient's healthy eye can be acquired to obtain image data of the healthy eye. In other implementations, medical image data of the patient's affected eye can also be acquired to obtain image data of the affected eye.

[0078] In some specific implementations, an impression can be taken from the patient's affected eye using injectable silicone to obtain an impression model. The obtained model is then subjected to three-dimensional scanning to obtain three-dimensional scan image data of the affected eye. Furthermore, a color image of the surface of the patient's healthy eye can be acquired using machine vision methods to obtain image data of the healthy eye.

[0079] In some specific implementations, medical image data of the patient's affected eye can be acquired using medical instruments such as computed tomography (CT), magnetic resonance imaging (MRI), and optical coherence tomography (OCT), and combined with the affected eye image obtained through the aforementioned modeling to obtain more accurate image data of the affected eye. Other techniques known in the art can be used to acquire eye image data, and are not limited thereto.

[0080] Step S2: Construct an initial three-dimensional data model of the prosthetic eye based on the image data of the affected eye. The initial three-dimensional data model is a simulation model with three-dimensional morphological features.

[0081] It should be noted that the initial three-dimensional data model is a simulation model with three-dimensional morphological features. In some embodiments, the initial three-dimensional data model includes an iris portion and / or a sclera portion, wherein the iris portion and / or the sclera portion have three-dimensional morphological features. For example, the outer surface of the iris portion may form a radial, uneven, ridge-like iris texture, and / or the outer surface of the sclera portion may form grooves with certain blood vessels, in order to simulate a real eyeball and improve the realism of the prosthetic eye.

[0082] In some implementations, the step of constructing an initial three-dimensional data model of the prosthetic eye based on the image data of the affected eye may specifically include:

[0083] Based on the image data of the affected eye, an initial three-dimensional data model of a prosthetic eye that matches the image data of the affected eye is obtained by filtering from a preset prosthetic eye database; or,

[0084] An initial three-dimensional data model of the prosthetic eye is constructed based on the image data of the affected eye, and the constructed initial three-dimensional data model of the prosthetic eye is stored in the prosthetic eye database.

[0085] In this embodiment, the prosthetic eye database stores a large amount of prosthetic eye data, such as iris data of different colors, sclera data of different whiteness, and prosthetic eye data of different sizes.

[0086] After constructing the initial three-dimensional data model of the prosthetic eye, the method further includes sculpting the initial three-dimensional data model so that the initial three-dimensional data model is a simulation model with three-dimensional morphological features.

[0087] In this embodiment, the three-dimensional data model of the prosthetic eye is sculpted. For example, software tool parameters such as pressure intensity, drawing width, and addition / subtraction parameters are selectively adjusted as needed to depict a simulation model with three-dimensional morphological features. For example, the outer surface of the iris is sculpted to form a radial, uneven, ridge-like iris texture, or the outer surface of the sclera is sculpted to form certain blood vessels and grooves to simulate a real eyeball and improve the realism of the prosthetic eye.

[0088] Furthermore, the initial three-dimensional data model of the prosthetic eye can be either a separate piece or a single piece. For example... Figure 2 As shown, when the initial three-dimensional data model of the prosthetic eye is a one-piece model, the initial three-dimensional data model of the prosthetic eye includes the pupil part 1, the iris part 2, and the sclera part 3. Figure 3 As shown, when the initial 3D data model of the prosthetic eye is a split model, it includes three independently set data models: pupil data model 1, iris data model 2, and sclera data model 3. The specific structure of the initial 3D data model of the prosthetic eye is selected according to requirements and is not limited here.

[0089] Step S3: Match the healthy eye image data with data samples in a preset prosthetic eye database, and determine the texture image data based on the similarity. The texture image data includes at least one of iris image data, pupil image data, blood vessel image data, and sclera image data.

[0090] In this embodiment, the pre-defined prosthetic eye database includes at least one of the following: prosthetic eye shape data samples, iris image data samples, pupil image data samples, blood vessel image data samples, and sclera image data samples. The database can be categorized into multiple sub-databases based on the type labels of the data samples. For example, the iris database contains iris image data samples of the same type but with different features.

[0091] Specifically, the step of matching the healthy eye image data with data samples in a preset prosthetic eye database and determining the texture image data based on similarity includes:

[0092] The healthy eye image data is matched with data samples in a preset prosthetic eye database, wherein the data samples include at least one of iris image data samples, pupil image data samples, blood vessel image data samples, and sclera image data samples;

[0093] When the similarity between the healthy eye image data and the data sample is greater than or equal to a preset threshold, the data sample is determined to be a texture image data; when the similarity between the healthy eye image data and the data sample is less than the preset threshold, the healthy eye image data is determined to be a texture image data, and the healthy eye image data is stored in the prosthetic eye database.

[0094] Similarly, the healthy eye image data includes iris image data, pupil image data, blood vessel image data, and sclera image data. This data can be integrated into a single image dataset or stored separately as individual images. When matching the healthy eye image data with data samples from the prosthetic eye database, the entire healthy eye image data can be matched sequentially with the corresponding data samples, or the healthy eye image data can be split into iris image data, pupil image data, sclera image data, and blood vessel image data, and then matched sequentially with the corresponding database data samples.

[0095] For example, when the similarity between the iris image data in the healthy eye image data and the iris image data samples in the prosthetic eye database is less than a preset threshold, the healthy eye image data is determined to be texture image data, and the healthy eye image data is stored in the prosthetic eye database. When the similarity between the iris image data in the healthy eye image data and the iris image data samples in the prosthetic eye database is greater than or equal to a preset threshold, the iris image data samples in the prosthetic eye database are determined to be texture image data.

[0096] The preset threshold can be set according to requirements. For example, if the preset threshold is set to 90%, when the similarity is greater than or equal to 90%, it is within the acceptable range, and the data sample is determined to be the texture image data; when the similarity matching value is less than 90%, it is within the unacceptable range, and the healthy eye image data is determined to be the texture image data. The preset threshold is not limited here.

[0097] Furthermore, when storing the healthy eye image data in the prosthetic eye database, the healthy eye image data can be split into iris image data, pupil image data, sclera image data, and blood vessel image data, and then stored in the corresponding iris database, pupil database, sclera database, and blood vessel database.

[0098] In practical applications, the healthy eye image data can also be directly fused with the initial 3D data model. In this case, high clarity of the healthy eye image data is required; low clarity may reduce the realism of the prosthetic eye. To ensure the realism of the prosthetic eye, designers need to adjust the healthy eye image data to outline the eyeball surface pattern, which is time-consuming. Therefore, using healthy eye image data to match highly similar data samples from a prosthetic eye database can significantly simplify the design process. Designers can directly call highly similar data samples, improving modeling efficiency and ensuring the realism of the prosthetic eye.

[0099] Step S4: The texture image data is fused with the initial three-dimensional data model to obtain the target three-dimensional data model of the prosthetic eye.

[0100] In this embodiment, as Figure 4 As shown, when the initial three-dimensional data model is an integrated model, the iris image data, pupil image data, sclera image data, and blood vessel image data in the texture image data are integrated into integrated image data, and then the integrated image data is fused with the initial three-dimensional data model to obtain the target three-dimensional data model.

[0101] like Figure 5 As shown, when the initial three-dimensional data model is a split model, the iris image data in the texture image data is fused with the iris data model 2 in the initial three-dimensional data model, the pupil image data is fused with the pupil data model 1, and the sclera image data and blood vessel image data are fused with the sclera data model 3 to obtain the target three-dimensional data model.

[0102] In another embodiment, when the texture image data is healthy eye image data and the initial 3D data model is a split model, the texture image data is split into at least one of iris image data, pupil image data, sclera image data, and blood vessel image data. The iris image data is then fused with iris data model 2 in the initial 3D data model, the pupil image data is fused with pupil data model 1 in the initial 3D data model, and the sclera image data and blood vessel image data are fused with sclera data model 3 to obtain the target 3D data model. When the initial 3D data model is a single-piece model, the texture image data is directly fused with the initial 3D data model to obtain the target 3D data model.

[0103] Specifically, the blending process employs UV mapping or other mapping methods known in the art, without limitation here.

[0104] Furthermore, such as Figure 5 As shown, after fusing the texture image data with the initial 3D data model, the manufacturing method further includes:

[0105] A data model of a transparent corneal structure 4 was constructed and placed on the outer surface of the fused initial 3D data model to obtain the target 3D data model of the prosthetic eye. The transparent corneal structure 4 is used to mimic the structure of a real human cornea, which can improve the gloss of the prosthetic eye surface and further enhance the realism of the prosthetic eye.

[0106] Step S5: Fabricate a prosthetic eye based on the target three-dimensional data model.

[0107] In this embodiment, the prosthetic eye is obtained by printing based on the three-dimensional data of the target three-dimensional data model using 3D printing technology. Exemplary 3D printing technologies that can be used include, but are not limited to, multi-nozzle printing (MJP), stereolithography (SLA), digital light processing (DLP), 3D printing technology (3DP), multi-jet melting (MJF), and various other types of 3D printing or additive manufacturing technologies known in the art, which are not limited herein.

[0108] This application constructs a three-dimensional data model of a prosthetic eye with three-dimensional morphological features. In the above scheme, an initial three-dimensional data model with three-dimensional morphological features is constructed based on the patient's affected eye image data. Then, data samples with high similarity to the healthy eye are matched with the image data of the patient's healthy eye in the prosthetic eye database. The data samples are directly called as the texture image data of the prosthetic eye, and the texture image data is fused with the initial three-dimensional data model. The whole design process is simpler and more convenient, shortens the design time, and designers can directly call data samples with high similarity, which improves modeling efficiency and improves the realism of the prosthetic eye.

[0109] The second aspect of this application also provides a prosthetic eye, such as... Figures 6-7 As shown, the prosthetic eye includes

[0110] The sclera 30 has a groove 31 at its center.

[0111] The iris 20 has a three-dimensional morphological feature on its outer surface. The iris 20 is annular and has a recessed area at its center. At least a portion of the iris 20 is embedded in the groove 31 of the sclera 30.

[0112] Pupil 10, at least a portion of which is embedded within a recessed area of ​​the iris 20; and

[0113] A transparent cornea 50, the inner surface of which abuts against the outer surface of the sclera 30.

[0114] In this embodiment, by setting three-dimensional morphological features on the outer surface of the iris, the folds, grooves, textures and other features in the iris can be simulated, making the prosthetic eye more three-dimensional and restoring the structure of the real eyeball, thus increasing the realism of the prosthetic eye; and it can be personalized based on the real data of the patient's healthy eye, making the processing simpler and more convenient.

[0115] In this embodiment, the prosthetic eye is made by 3D printing technology. Specifically, the target 3D data model is first obtained through the manufacturing method described in the first aspect, and then the prosthetic eye is made by 3D printing technology based on the target 3D data model. This will not be elaborated further here.

[0116] In one embodiment, such as Figure 7 As shown, the pupil 10, iris 20, sclera 30, and transparent cornea 50 are all detachable and connectable. The color of the iris 20 and / or the color of the sclera 30 matches the color of the patient's healthy eye. When a patient wears colored contact lenses that differ from their own iris 20 for aesthetic purposes, the one-piece prosthetic eye is difficult to match the color of the healthy eye. Furthermore, the color of the sclera 30 changes with age, and without replacing the prosthetic eye, it is difficult to match the color of the healthy eye. The various components of the prosthetic eye are detachable and replaceable, allowing for the replacement of components with corresponding colors based on the color of the healthy eye, thus enhancing the realism of the prosthetic eye.

[0117] Furthermore, a groove 31 is provided at the center of the sclera 30, and at least a portion of the iris 20 is embedded in the groove 31 of the sclera 30. The iris 20 is annular, and at least a portion of the pupil 10 is embedded in the concave area of ​​the iris 20. The inner surface of the transparent cornea 50 abuts against the outer surface of the sclera 30. Even further, the sclera 30 has a hollow structure to reduce the weight of the prosthetic eye, thereby reducing the burden on the patient.

[0118] Furthermore, the bottom surface of the sclera 30 may be provided with a soft layer (not shown in the figure). In this embodiment, the bottom surface of the sclera is the mounting surface of the prosthetic eye. Providing a soft layer on the bottom surface can improve the patient's comfort when wearing the prosthetic eye. The bottom surface can be curved or flat. To facilitate the installation and connection of the prosthetic eye, the soft layer can be made of a soft material, and the soft layer covers the bottom surface. Moreover, the soft material has adhesive properties, thereby making the bottom surface adhesive, which facilitates the installation of the prosthetic eye on the prosthetic eye platform or other mechanisms.

[0119] In this embodiment, the transparent cornea 50 is lenticular in shape, achieving a light-gathering effect and improving the gloss of the prosthetic eye surface, thus enhancing its realism. Furthermore, to further improve the realism of the prosthetic eye, the outer surface of the iris 20 is concave lenticular, and the outer surface of the sclera 30 is provided with a macula and / or blood vessels 40. The iris 20 and / or sclera 30 are designed according to the patient's ocular characteristics, and the size, color, and texture of the iris 20, sclera 30, and blood vessels 40 can all be obtained from a color image of the healthy eye surface.

[0120] Furthermore, the pupil has a hollow portion (not shown in the figure), and a sensor is installed in the hollow portion. The sensor can transmit the collected external information to the prosthetic eye platform controller or an external processing device, so as to transmit it to the patient's retinal ganglion cells, providing information to the patient and enhancing the patient's self-confidence.

[0121] This application also provides a prosthetic eye, including the aforementioned prosthetic eye piece and prosthetic eye mount. The prosthetic eye piece can be any of the prosthetic eye pieces described in the above embodiments, and the prosthetic eye mount is used to mount the prosthetic eye piece; the specific structure of the prosthetic eye mount is not limited here.

[0122] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
