ARTIFICIAL INTRAOCULAR LENS Russian patent published in 2012 - IPC A61F2/16 

FIELD: medicine.

SUBSTANCE: invention relates to field of ophthalmic surgery. Artificial intraocular lens (AEL) contains optic and support elements, anterior surface of optic element is flat, posterior surface of optic element is made in form of segments of elliptical, hyperbolic and parabolic surfaces. In the centre of posterior surface additionally located is first segment of hyperbolic surface, ratio of diameter of said hyperbolic to diameter of optic part lies in the interval from 0.1 to 0.3. Second part of posterior surface is made in form of segment of elliptical surface, ratio of diameter of elliptical surface segment to diameter of optic element lies in the interval from 0.1 to 0.3. Third part of posterior surface is made in form of segment of second hyperbolic surface, ratio of diameter of hyperbolic surface segment to diameter of optic element lies in the interval from 0.2 to 0.4. Peripheral part of posterior surface is made in form of segment of parabolic surface, ratio of diameter of said surface to diameter of optic element lies in the interval from 0.2 to 0.4.

EFFECT: application of claimed invention will make it possible to simultaneously increase acuity of photopic and scotopic and peripheral vision to intact level.
