Cryotherapy is used to treat retinal tears, early retinal detachments, tumors, vascular lesions, and different retinopathies. This procedure is very similar to a laser treatment and consists of transmitting freezing temperatures to the retina by use of a small probe on the exterior surface of the eye. The intense cold can seal retinal tears and leaking retinal blood vessels.
Vision may be blurred and some discomfort is expected after this procedure. The eye will be patched for a number of hours. Healing time typically takes about 2 weeks.
