Abstract
FIELD: ophthalmology. SUBSTANCE: artificial CRYSTALLINE lens has optical member which is made of two lenses. The optical member is placed into air-tight case. Lenses of optical member are separated by air space. The first lens has negative focal power. Radius of curvature of the second surface of the lens is positive and equals to 0.2-0.8 focal distance of optical member. The second lens is positive and has focal power being equal to 1.1-3.0 focal power of the member. EFFECT: simplified design; improved depth of focus.
