Title:
A SYSTEM AND METHOD OF DETERMINING AND ANALYSING THE OCULAR BIOMETRIC STATUS OF A PATIENT
Document Type and Number:
WIPO Patent Application WO/2021/123455
Kind Code:
A3
Abstract:
A computer implemented system and method for determining and analysing ocular refractive error of an eye. The method determines a set of sample biometric factors for a reference sample of eyes from a set of reference sample physical characteristics. Physical characteristics of a patient's eye are measured such that the type of measured patient physical characteristics include some or all of the reference sample characteristic types. Patient biometric factors are then calculated based on the measured and inherent patient physical characteristics and compared with the sample biometric factors to determine the effect of one or more parameters on the ocular refractive error of an eye. The method may calculate the difference between the refractive contribution of the axial length, cornea and internal optics in the patient's eye and the separate contribution from those factors in the sample physical characteristics.
