Abstract

• A new prismatic type of lens enables a more peripheral view of the vitreous cavity. The surface in contact with the cornea is concave. The opposite surface is piano but inclined to produce a prismatic effect of 15° or 25°. A cannula attached to the lens provides corneal irrigation. Although this lens was originally designed for vitrectomy use, it is also useful for diagnostic biomicroscopy of the vitreous and fundus in the office.
