ARTIFICIAL CRYSTALLINE LENS WITH GRADUATED INTRAOCULAR CHANGE IN FOCAL POWER Russian patent published in 2006 - IPC A61F2/14 

FIELD: ophthalmology; surgery.

SUBSTANCE: artificial crystalline lens has haptic and optic parts; the lens is made of components. Haptic part is made of two combined parts. First pat is made in form of two support members, tightly connected in one point. Any member is made in form of arc which changes into open spiral. Recess is made onto internal part of arc. Ends of spirals are oriented in opposite to each other. Second part of haptic part has to be a ring which has at least one recess onto its external surface. The recess is made for interaction with internal recess onto internal surface of arc. Internal surface of ring is tightly connected with edge surface of at least one lens.

EFFECT: widened range of technical aids, namely, designs of artificial crystalline lenses.
