ACCOMMODATING INTRAOCULAR LENS Russian patent published in 2009 - IPC A61F2/16 

FIELD: medicine; ophthalmology.

SUBSTANCE: bearing supports are composite. The first bearing support presents a closed ellipsoid elastic light-transmitting polymer enclosure filled with light-transmitting liquid and a congruent internal surface of capsular sac. The first bearing support changes its geometry and reciprocates along the lateral symmetry axis matching the central optical axis of an optical element. The front surface of the first bearing support contains at least three stop lugs at an acute angle to surface of the first bearing support and arranged at the same angular distance and directed inside and towards the central optical axis. The back surface of the second bearing support represents a curvilinear elliptic warped surface interacting with a front surface of the first bearing support and congruent thereto. The front surface of the second bearing support is connected with a cylindrical optically-transparent body with the symmetry axis matching the central optical axis of the elastic optical element consistently connected to the cylindrical body. The second bearing support and the optical element reciprocate along the central optical axis.

EFFECT: improved accommodating properties of AIOL, reduced local deformations of capsular sac tissues.
