title: Assistant-independent OptiFlex system for contact and noncontact wide-angle viewing in vitreoretinal surgery.
abstract: The wide-angle viewing system during vitreoretinal surgery has lead to an increased success rate of complex procedures. Two types of wide-angle viewing systems are in use, contact and noncontact, each with its own advantages and disadvantages. In this article, we describe an optical system, OptiFlex, that is designed to combine the advantages of the contact and noncontact systems by enabling the surgeon to switch between them with ease and without skilled surgical assistance.
