INTRAOCULAR LENS Russian patent published in 2009 - IPC A61F2/14 

FIELD: medicine.

SUBSTANCE: intraocular lens includes an optical part and support elements. The intraocular lens is composite and consists of two intraocular lenses. The optical element of the first intraocular lens is made in form of a segment of a biconvex lens, the chord of which lies horizontally on the line of the optical axis of the intraocular lens. The arc of the chord of the optical element of the first intraocular lens faces downwards with respect to the line of the optical axis of the intraocular lens, and the principal plane of the optical element of the first intraocular lens is parallel the principal plane of the optical element of the second intraocular lens. The optical element of the first intraocular lens is in front of the capsular sack. Support elements of the first intraocular lens are in form of at least, three curvilinear arcs, which interact with a capsular ring installed in the capsulorhexis zone, and is the first part of the support elements of the second intraocular lens, which interact with the second part of the support elements of the second intraocular lens, made in form of at least three arcs joined by one side to the capsular sack, and with the other to the rear surface of the optical part of the second intraocular lens. The arcs are congruent to the shape of the inner surface of the capsular sack, and the rear surface of the optical part of the second intraocular lens is congruent to the rear surface of the capsular sack.

EFFECT: improvement of spatial distribution of local deformations of tissue of the capsular sack, reduction of the size of these deformations, reduction of injury of tissue of the capsular sack and provision for good near and far eyesight.
