EYE'S ARTIFICIAL CRYSTALLINE LENS Russian patent published in 1997 - IPC

FIELD: ophthalmosurgery. SUBSTANCE: proposed artificial crystalline lens comprises supporting part and optical part. Radius of concave rear surface of optical part is equal to radius of concave rear surface of supporting part and corresponds to radius of curvature of eye's natural crystalline lens. Frontal surface of optical part constitutes convex surface of revolution of at least first order. Ratio of supporting part height to height of eye's artificial lens lies within range 0.3 to 0.98. Ratio of supporting part thickness to supporting part length lies within range 0.011 to 0.015. Ratio of eye's artificial lens height to supporting part length lies within range 0.095 to 0.192, while ratio of optical part diameter to lens' supporting part length lies within range 0.153 to 0.7. EFFECT: greater efficiency of corrective treatment in medium- and high-degree hypermetropia cases. 7 cl, 2 dwg
