Identifying changes in ocular refractive anomalies

摘要

The present invention relates to a method (210), a device (110) and a computer program for specifying a refractive index of an eye (112) of a user (114).In a method (210) for identifying the refractive error of the eye (112) of the userThe eye (112) of the user (114) has a choroid (124);A) of the choroid (124) of the eye (112) of the userCheck at least one value (122) of the layer thickness (120) across at least one area (150) of the choroid (124) andB) the step of determining the value (216) of the refractive index change of the eye (112) from at least two values of the thickness (122) of the choroid (124);Each step is confirmed at different times for at least one region (150) of the choroid (124) andIncludeAt least one areaIt is selected from the nasal lateral foveal region (168) or nasal lateral fovea area (166).
