Abstract
A lens arrangement for use in vitreoretinal surgery includes a contact lens element including a posterior surface having a shape adapted to fit an average cornea for placement on a patient's eye and an anterior surface. The contact lens element transmits light emanating from the patient's eye for viewing a structure of the patient's eye. A flange surrounds and 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 allowing access to an incision through which a surgical tool or instrument may be inserted into the eye.
