Abstract

A lens arrangement for use in vitreous retinal surgery includes a contact lens element (18) including a posterior surface (12) having a shape adapted to fit an average comes for placement on a patient's eye, and an anterior surface (24). The contact lens element transmits light emanating from the patient's eye for viewing a structure of the patient's eye. A flange (30) surrounds, holds a peripheral region of the contact lens element, and extends radially onto the scleral region of the patient's eye.
The flange has a posterior surface with a shape adapted to fit an average scleral curvature so that the flange rests on the sclera for stabilizing a position of the contact lens on the patient's cornea.
The flange includes at least one opening (50) allowing access to an incision through which a surgical tool or instrument may be inserted into the eye.
