ARTIFICIAL BASE EYE LENS FOR MAKING SURGICAL APHAKIA CORRECTION IN CHILDREN, CORRECTIVE ARTIFICIAL EYE LENS FOR TREATING PSEUDOPHAKIC EYE AMETROPIA IN REMOTE POSTOPERATIVE PERIOD IN CHILDREN AND METHOD FOR IMPLANTING IT Russian patent published in 2007 - IPC A61F2/16 A61F9/07 

FIELD: medical engineering.

SUBSTANCE: artificial base eye lens has optic supporting members. Four similar identical rectangular projections manufactured from optically transparent material. Each projection begins from optical part edge and ends 2.25-2.5 mm far from its center, is 0.75-3.5 mm long and 0.2 mm wide and high. The corrective artificial eye lens has optic supporting members. Optical part diameter id equal to 4.5 mm. The supporting members are arranged in the same plane with the optical part and are manufactured as four identical leaflets of oval shape being the same angular distance far from each other. Each leaflet width is less than space separating neighboring projections of the artificial base eye lens when measuring at the same distance from the optical center. Leaflet apices are inscribed into a circle of 10-11 mm large diameter concentrically arranged with respect to the optical part. The eye lens is manufactured as monolith from soft transparent polymer material. When implanting the corrective artificial eye lens, it is fixed on anterior surface of the artificial base eye lens. Spatula is introduced between posterior surface of the anterior capsule and anterior surface of the artificial base eye lens. The anterior eye lens capsule is detached from the anterior surface of the artificial base eye lens. Four pockets are formed in turn, each beginning between two neighboring artificial base eye lens projections and ending at peripheral capsule sack part. The corrective artificial eye lens is introduced into eye cavity in folded state. It is spread in the anterior chamber and supporting members are introduced as leaflets into preliminarily prepared pockets.

EFFECT: reduced risk of complications; high rehabilitation quality.
