FIELD: medicine.

SUBSTANCE: device has optical and haptic parts. The haptic part is ring of variable geometric shape. The internal ring surface is connected to optical part end face surface allowing reciprocation along the optical axis of the artificial eye lens with at least three logarithmic spirals curved clockwise to the same side and allowing changes of their curvature in ring plane, and in space together with the optical part. At least three concave curvilinear angularly equidistant unclosed segments are available on ring surface and turned with their convex side towards the optical part and with the unclosed part towards the opposite direction. Curvilinear unclosed segments and the haptic part have variable shape.
