[Intraocular lens for correction of aphakia in cataract extraction through a small incision]

The purpose of this study was to create an intraocular lens (IOL) reliably fixed in the capsular sac and convenient for implantation through a tunnel incision. Our design consists from a biconcave lens 5 mm in diameter and 2 vis-a-vis C-shaped open haptic elements at an angle of 110 degrees to the optic component. The total diameter of IOL is 12 mm. The lens is made from rigid material (oligocarbonate methacrylate). IOLs of this design were implanted in 164 eyes. No complications were recorded. The studies indicate that this design ensures good mobility and elasticity of the supporting elements of the lens at the site of their bending and connection to the optic part. This results in even and most complete filling of the capsular sac equator with supporting elements and the maximal retraction of the sac, which creates conditions for reliable fixation of IOL, prevents development of fibrous changes, decentration and dislocation in the postoperative period.
