METHOD OF DETERMINING THE RADIUS OF INTRASTROMAL OPTICAL LENSE CURVATURE FOR CORRECTING PRESBYOPIA Russian patent published in 2016 - IPC A61F2/14

Abstract RU 2591662 C1

FIELD: medicine.

SUBSTANCE: invention relates to ophthalmosurgery. Method of determining the radius of curvature of the front surface intrastromal optical lens (INLAY) for correction of presbyopy including refraction indices of the corneal stroma (N_keratoderma), material of optical lens (N_mater.) and rear surface curvature radius R_rear. Optical lens implantation depth H in mcm and value of required presbyoptic component D_presb in dioptre difference are determined, and radius of curvature R of front surface of INLAY in mm is determined by formula

EFFECT: using given invention enables higher accuracy of correction of presbyopy.
