Super-reversed intraocular lens

Abstract

An intraocular lens (IOL) with an inverse (reversed) optic has the convex surface directed toward the retina, a design which has many advantages. We have developed a "super-reversed" IOL by increasing the angle of the haptic from 10 to 20 degrees and by increasing the convexity of the posterior surface (necessitating a concave anterior surface). The main advantage of this model is the distance of approximately 6.3 mm between the anterior corneal surface and the posterior IOL surface. This configuration mimics the natural situation. We report on the implantation of 473 lenses of this design.
