Definition

Retinal cryopexy, also called retinal cryotherapy, is a procedure that uses intense cold to induce a chorioretinal scar and to destroy retinal or choroidal tissue.

Purpose

The retina is the very thin membrane in the back of the eye that acts like the "film" in a camera. It is held against the inside back portion of the eye by pressure from fluid within the eye. In the front part of the eye, the retina is firmly attached at a ring just behind the lens called the pars plana. In the back part of the eye, the retina is continuous with the optic nerve. In between the pars plana and the optic nerve the retina has no fixed attachments. The retina collects information from the images projected on it from the eye lens and sends it along the optic nerve to the brain, where the information is interpreted and experienced as sight.

Other Information

Approximately 56% of all patients achieve results of 20/20 or better and over 90% achieve 20/40 or better (which is good enough to drive without corrective lenses in most regions).1 Those with moderate to high myopia (greater than 7 diopters) have a lesser chance of achieving that result. As technique and technology improve, the results continue to improve.
