Description

[Technical Field]

[0001] The present invention provides data on the progression of a person's refractive index. decision The present invention relates to a processing device, a computer-implemented method and a computer program for performing the same, and a system, a computer-implemented method and a computer program for providing data on the progression of refractive values. [Background technology]

[0002] Pascolini D. & Mariotti SP, "Global estimates of visual impairment: 2010," Br J Ophthalmol 2012;96:614e618. doi:10.1136 / bjophthalmol-2011-300539, describes visual impairment as a global health and socioeconomic problem characterized by uneven distribution. The leading cause of visual impairment is uncorrected refractive error, accounting for 43% of cases. Despite the emergence of preventive measures, the situation has not changed significantly over the past decade, and uncorrected refractive error still appears on the list of leading causes of visual impairment in various regions of the world.

[0003] Grzybowski A. et al., A review on the epidemiology of myopia in school children worldwide, BMC Ophthalmology (2020) 20:27, noted a 60% myopia prevalence in Asian countries, with East Asian countries showing an even higher prevalence of 73%. Furthermore, this study found a 40% myopia prevalence in European countries and a 42% myopia prevalence in North American children. In contrast, African and South American countries show a myopia prevalence of less than 10%.

[0004] Dong L. et al., Prevalence and time trends of myopia in children and adolescents in China, Retina 40(3); 2019, pp-399-411, describes a recent meta-analysis on the prevalence and trends of myopia in Chinese children and adolescents, estimating that the prevalence of myopia could reach 84% in 30 years.

[0005] Considering the visual and pathological consequences of myopia and high myopia, it is important to address this problem early. The standard methods for correcting refractive errors such as myopia are glasses, contact lenses, or refractive surgery. However, based on current and projected estimates of refractive errors worldwide, these methods only correct the error and may not be sufficient to reduce further progression.

[0006] In addition to these mentioned correction methods, Wallin JJ et al., "Interventions to slow progression of myopia in children," 2020, Cochrane Database Syst Rev. 1: CD004916; https: / / doi.org / 10.1002 / 14651858.CD004916.pub4, indicates that various solutions have proven successful in slowing or halting myopia progression. Examples include the use of different doses of atropine, spectacle lenses, specifically bifocals, progressive power lenses, multi-segment lenses with peripheral defocus or defocusing, multifocal contact lenses, and orthokeratology.

[0007] Whether a certain type of myopia treatment is suitable for a person depends primarily on that person's risk of developing myopia and progressing myopia. Morgan IG et al., "IMI Risk Factors for Myopia," Invest. Ophthalmol. Vis. Sci. 2021;62(5):3, reports that the myopia community has invested significant effort over the past several decades to understand the key parameters that may influence this risk. Numerous variables have been suggested to influence the onset and progression of myopia, but only a handful are frequently cited. Among these parameters are ethnicity, behavior, and parental myopia.

[0008] The Myopia Calculator, available via https: / / bhvi.org / myopia-calculator-resources / , provides online software for predicting a person's refractive error progression by using data about the person, including the person's age, ethnicity, and refractive error, and the recommended myopia treatment to be applied to the person. Based on this, the software calculates a predicted rate of reduction in myopia progression compared to a standard corrective procedure, such as single vision spectacle lenses, and a predicted course of the person's refractive error if the recommended myopia treatment is initiated immediately.

[0009] MyAppia, available via https: / / myopiacare.com / myappia-myocalc / , provides further online software for predicting the progression of a person's refractive value by using data about a person, including age, the person's refractive state, including the spherical equivalent of the person's eye, and one or more recommended myopia treatments to be applied to the person. Based thereon, the software calculates both a rate of reduction in myopia progression and a predicted value for the course of the person's refractive error based on one or more recommended types of myopia treatments to be applied to the person.

[Means for solving the problem]

[0024] The problem is related to the provision of data relating to the progression of a person's refractive value, which has the features of the independent claim. decision The object of the present invention is achieved by a processing device, a computer-implemented method and a computer program for providing data on the progression of refraction values, and a system, a computer-implemented method and a computer program for providing data on the progression of refraction values. Preferred embodiments, which can be implemented alone or in any free combination, are recited in the dependent claims and in the following description.

[0025] In a first aspect, the present invention provides a method for collecting data relating to the progression of a person's refractive index. decision According to the present invention, the processing device comprises: - data relating to a person, ·The person's refractive state and the person's age, sex and ethnicity; At least one risk factor for the person receiving data including: - Use at least one machine learning algorithm to analyze data about a person's refractive progression decision and wherein the at least one machine learning algorithm determines a relationship between data about the person and the progression of the person's refraction value. decision at least one predictive model for decision To do The device is configured to:

[0026] As used herein, the term "processing" or any grammatical variations thereof refers to applying at least one algorithm to data received via at least one input file, such that desired data regarding the progression of a person's refraction value is provided via at least one output file for further processing. As generally used, the term "data" refers to at least one piece of information contained in at least one file, specifically at least one input file or at least one output file. In particular with respect to the present invention, at least one piece of information contained in the at least one input file may relate to a person, and at least one piece of information contained in the at least one output file may relate to the progression of a person's refraction value. The at least one algorithm derives data regarding the progression of a person's refraction value from data related to the person by using data from the at least one input file according to a predetermined scheme. decision The method may be configured to perform the above steps, and may also apply artificial intelligence, in particular at least one machine learning algorithm, as will be described in more detail below.

[0027] As generally used, the term "processing device" preferably refers to a device that processes data relating to the progression of a person's refraction value from data relating to the person received from at least one input file, which may be provided to the processing device by at least one input interface. decision"refers to an apparatus designed to provide data relating to the progression of a person's refraction values, preferably via at least one output interface, for further processing, in particular by using a system as described in more detail below. In particular, the processing device may comprise at least one integrated circuit, in particular an application specific integrated circuit (ASIC), or a digital processing device, in particular at least one digital signal processor (DSP), field programmable gate array (FPGA), microcontroller, microcomputer, computer or electronic communication unit, in particular at least one smartphone, tablet, personal digital assistant or laptop. Further components may be possible, in particular at least one of a data acquisition unit, a pre-processing unit or a data storage unit. The processing device preferably comprises at least one computer program, in particular a processor for storing data relating to the progression of a person's refraction values. decision The computer may be configured to execute at least one line of computer program code configured to execute at least one algorithm for:

[0028] According to the invention, the processing device derives data relating to the progression of the person's refraction value from data relating to the person that may be received from at least one input file. decision In general use, it is configured to decision The term "person" or any grammatical variant thereof typically refers to a process that generates a representative result, denoted "data." In particular with respect to the present invention, the data thus generated includes pieces of information relating to the prediction of the refractive value of at least one eye of a person. Instead of the term "person," other terms such as "user," "patient," "individual," or "wearer" may be applied.

[0029] As described above, the data related to the person includes the person's refractive state. Preferably, the data related to the person's refractive state can include at least one refraction value of at least one eye of the person. As used herein, the term "at least one eye" refers to one or both eyes of the person. As generally used, the term "refractive value" corresponds to at least one refractive error of at least one eye of the person, which can be used in particular to manufacture at least one optical lens, in particular at least one spectacle lens or at least one contact lens, each of which indicates a refractive power that can correct at least one refractive error of at least one eye of the person based on the refraction value. Furthermore, as generally used, the term "progression of refraction value" refers to a prediction of a temporal change, particularly a decrease, particularly a monotonic decrease, in the refraction value of at least one eye of the person over a certain period of time. Based on standard ISO 13666:2019 section 3.5.2, referred to herein as the "Standard," the term "spectacle lens" refers to an optical lens used to correct at least one refractive error of at least one eye of a person, where the optical lens is held in front of the person's eye, thereby avoiding direct contact with the person's eye. Accordingly, the term "contact lens" refers to an optical lens used to correct at least one refractive error of at least one eye of a person, where the optical lens is worn in direct contact with the person's eye. Furthermore, the term "spectacle" refers to an element including two individual spectacle lenses and a spectacle frame, where each spectacle lens is prepared to be received by a spectacle frame selected by the person.

[0030] In the context of the present invention, the at least one refractive value may be selected from values ​​of sphere, and preferably also cylinder, of an ocular lens of at least one human eye. As defined in the Standard, Section 3.12.2, the term "spherical power", usually abbreviated as "sphere" or "sph", refers to the value of the back vertex power of a spherical power lens. As defined in the Standard, Section 3.13.7, the term "cylinder", usually abbreviated as "cylinder" or "cyl", refers to the algebraic difference between the principal powers, where the power of the principal meridian selected for reference is subtracted from the other principal powers.

[0031] Alternatively or additionally, the data regarding the refractive state of a person may be or include at least one biometric value of at least one eye of the person. As commonly used, the term "biometric value" refers to a measurement of at least one extension of at least one feature of at least one eye of a person in three-dimensional space, and thus may typically be expressed using a value indicating a spatial extension and a corresponding unit, such as meters. In the context of the present invention, the biometric value may particularly include both the axial length and the corneal radius of curvature of at least one eye of the person, and the anterior chamber depth or ocular thickness may further be used as at least one of the biometric values. However, it may also be possible to select at least one different biometric value. Furthermore, those skilled in the art know that at least one refractive value of at least one eye of a person is closely related to at least one biometric value of at least one eye of the person. In practice, there are known relationships that can be applied to convert a first value related to at least one biometric value into a second value related to at least one refractive value, or vice versa. Thus, both at least one refractive value of a person and at least one biometric value of at least one eye of the person are covered by the term "refractive state" of the person.

[0032] As more generally used, the term "refractive power" or simply "power" refers to the capacity of a lens, specifically a spectacle lens or contact lens, to change at least one of the curvature or direction of an incident wavefront by refraction, as defined in the Standard, Section 3.1.10. As more generally used herein, the term "myopia" relates to a person's refractive condition in which the refractive power of at least one of the person's eyes is estimated to be less than -0.5 dpt. As more generally used, the term "high myopia" refers to a person's refractive condition in which the refractive power of at least one of the person's eyes is estimated to be less than -6.0 dpt. As more generally used, the term "myopia progression" refers to a prediction of the temporal change, particularly a decrease, especially a monotonic decrease, in the refractive power of at least one of the person's eyes over a period of time. Here, the prediction period can cover several years, preferably 1 to 12 years, more preferably 2 to 10 years, and particularly 4 to 8 years. However, it may be possible to use different periods. Further as used herein, the term "myopia onset" refers to the point in the progression of myopia at which the refractive power of at least one eye of a person decreases from above -0.5 dpt to below -0.5 dpt.

[0033] As described above, data about a person further includes personal data, namely, the person's age, gender, and ethnicity. As commonly used, the term "age" refers to the time since a person's birth, preferably expressed in years. The present invention may be applicable to people who are children, juveniles, or young adults, particularly those aged 4 to 24, and particularly those aged 5 to 20. However, the present invention may also be applicable to people of different ages. Furthermore, as commonly used, the term "gender" refers to a person's identification with the terms "female" and "male," although non-binary identification may also be possible. Furthermore, when commonly used, the term "ethnicity" refers to a person's assignment to a particular group. While not wishing to be bound by theory, Morgan IG et al., referenced above, summarize that the evidence and causal relationship between a person's gender and ethnicity, on the one hand, and myopia progression, on the other, is weak or inconsistent. Nevertheless, as presented in International Publication No. 2020 / 083382A1, a trained machine learning algorithm can generate more accurate predictions for people belonging to at least one of a particular gender or group compared to a machine learning algorithm trained using a mixed-population training set.

[0034] According to the present invention, the data on a person includes at least one risk factor on the person. As commonly used, the term "risk factor" refers to at least one value of a condition or process on a person that has been proven to increase or decrease myopia progression in at least one eye of the person and / or increase or decrease the time of myopia onset. Without wishing to be bound by theory, according to Morgan IG et al., referenced above, risk factors can be selected to be useful for designing myopia treatment, preferably by demonstrating a causal relationship related to a defined mechanism between the assumed risk factor and observed myopia treatment, on the one hand, particularly by using the association with the condition or process, and the myopia progression, on the other hand, which can be demonstrated using cross-sectional data or preferably longitudinal data of a defined population. For the definition of different types of data, please refer to the following explanation.

[0035] In a particularly preferred embodiment, at least one risk factor can be selected from the data on the refractive status of at least one parent of a person.For the term "refractive status", refer to the above definition applicable to at least one parent of a person, mutatis mutandis.According to Morgan IG et al., referenced above, the evidence and causal relationship between the refractive status of at least one parent of a person on the one hand and the progression of myopia on the other hand is strong, regardless of whether it is based on the inheritance of genetic variants that predispose children to myopia or on a myopic lifestyle.

[0036] Alternatively or additionally, at least one risk factor may be selected from data on at least one parameter related to a person's behavior. As commonly used, the term "behavior" refers to a person's repetitive activities that expose at least one of the person's eyes to optical radiation. Furthermore, as commonly used, the term "optical radiation" refers to electromagnetic waves having wavelengths between 380 nm and 780 nm, defining the "optical wavelength range" so designated. For purposes of the present invention, adjacent wavelength ranges, particularly radiation from the wavelength range between 100 nm and less than 380 nm, designated the "long ultraviolet wavelength range," and / or radiation from the wavelength range between 780 nm and 1.5 μm, designated the "near-infrared wavelength range," may also be considered. While not wishing to be bound by theory, Morgan IG et al., referenced above, show that there is strong evidence and causal relationship between, on the one hand, a person's behavior and, on the other hand, myopia progression, particularly depending on at least one parameter of optical radiation, particularly at least one parameter of optical radiation related to the intensity, spectral distribution, and duration of optical radiation incident on at least one of a person's eyes.

[0037] According to the invention, at least one parameter relating to the person's behavior is: The first amount of time spent on near-sighted tasks by the person, The second amount of time spent outdoors by a person The data is selected from data relating to at least one of the above.

[0038] As commonly used, the term "near-sightedness task" refers to a first type of repetitive activity of a person dedicated to directing their eyes toward an object located at a distance from their eyes so that their eyes can adapt to a near point. As commonly used, the term "adapt" or any grammatical variant thereof refers to adjusting the refraction of a person's eye relative to the retinal surface of their eye when imaging an object located in front of their eye between a near point and a far point. The term "far point" refers to the end point of the refraction direction of a person's eye without adaptation, and the term "near point" refers to a point indicating the minimum distance in front of their eye at which an object can still be clearly imaged on the retinal surface of their eye, and the near point is an individual quantity, particularly depending on the person's age. Here, a fixed position of the person's eye, particularly on the cornea, such as the position of the observable corneal reflex, can serve as a reference point for measuring the distance of the near point to their eye. In practice, the object of a person's near-sightedness task may be, in particular, a text object or a mobile communication device. As used herein, the term "text object" refers to a type of object containing printed information, particularly selected from books, pamphlets, or newspapers. Furthermore, the term "mobile communication device" refers to at least one electronic device configured to present information by using an electronically driven screen, which can be carried by a person and therefore can move with the person, and is selected in particular from a smartphone, a notebook, a personal digital assistant or a laptop. However, further types of objects may also be feasible.

[0039] Furthermore, as commonly used, the term "time spent outdoors" refers to a second type of repetitive activity performed by a person outdoors outside of a building, particularly during or after daycare or school, on weekends, or during vacations. As noted above, the intensity of light radiation incident on at least one eye of a person can be significantly increased during the second amount of time spent outdoors by a person. While not wishing to be bound by theory, Morgan IG et al., referenced above, show that a strong and consistently observed association between time spent outdoors and reduced myopia progression exists, but there is debate as to whether increasing time spent outdoors not only reduces myopia progression but also reduces the onset of myopia.

[0040] The more commonly used term "amount of time" refers to the period during which a person's respective repetitive activity is performed, especially by using the person's average occupancy expressed in hours per day or hours per week. decision For this purpose, the period regularly spent outside on holiday can be used, however, it is preferably feasible to further modify this value by adding the period spent outside on holiday, thereby taking into account the annual duration of holiday compared to the annual duration of school time or nursery time.

[0041] In a preferred embodiment, the data about the person may further include at least one type of myopia treatment applied to the person. As commonly used, the term "type of myopia treatment" refers to at least one type of preventive intervention configured to at least one of reduce myopia progression or delay myopia onset in at least one eye of the person. In particular, the type of myopia treatment may include the application of at least one optical lens to at least one eye of the person. Here, at least one of the optical lenses may preferably be selected from spectacle lenses or contact lenses. In particular for certain types of myopia, the spectacle lenses may be selected from, in particular, bifocal lenses, progressive power lenses, peripheral defocus lenses, or multi-segment lenses incorporating defocus, while the contact lenses may preferably be selected from multifocal contact lenses or orthokeratology lenses. As defined in the Standard, Section 3.7.3, the term "bifocal lens" refers to a specific type of spectacle lens having two portions, each portion having a different value for refractive power. Similarly, the term "progressive addition lens" refers to another type of spectacle lens with a smooth change in refractive power without discontinuities across the lens surface, as defined in the Standard, Section 3.7.7-8. Furthermore, the term "peripheral defocus lens" refers to another type of spectacle lens with a change in optical power from the central optical zone to the periphery, thereby inducing peripheral defocus in decentered regions of the retina. Furthermore, the term "multi-segment lens with integrated defocus" refers to another type of spectacle lens that includes a central optical zone for correcting distance refractive error and an annular multifocal zone that can include segments with different refractive powers compared to the central optical zone. Furthermore, the term "orthokeratology lens" refers to a gas-permeable contact lens configured to temporarily reshape the cornea to change the refractive power of at least one eye of a person. However, other types of spectacle lenses or contact lenses may also be used.

[0042] Alternatively or additionally, the type of myopia treatment may be selected from the application of at least one of a dose of a drug, particularly a dose of atropine, or refractive surgery, however, applying at least one of a drug or refractive surgery may only correct the current refractive error and may not be sufficient to mitigate further myopia progression.

[0043] Further, in accordance with the present invention, the processing device may compile data regarding the progression of a person's refraction value by using at least one machine learning algorithm. decision As commonly used, the term "machine learning" refers to a process of applying artificial intelligence to automatically generate a model for at least one of classification or regression, where at least one machine learning algorithm configured to generate a desired model based on multiple training datasets can be preferably used. As more commonly used, the term "training" refers to the process of providing multiple training datasets and executing them through specific method steps to generate desired data during a training phase. decision It is shown that the performance of the method steps is improved. Herein, each training data set used for training purposes resembles an expected data set, such as data on the progression of a person's refraction value, but includes known data. For this reason, a particular method step is performed using a particular training data set, and the content results thus obtained are adjusted to the known data from the particular training data set. Herein, in order to improve the approximation of the results achieved during the execution of a particular method step, multiple training data sets are iteratively applied during a training phase, specifically by repeating the training of a particular method step until the deviation between the data obtained by performing a particular method step and the known data contained in each training data set can be below a threshold.
