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 plano but inclined to produce a prismatic effect of 15 degrees or 25 degrees. 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.
