How is Cryopexy performed?
Cryopexy to correct a disorder of the retina is performed using local anesthesia. The treatment is performed on-site at our retina center. During the treatment, a metal probe is placed against the eye. The tip of the probe becomes very cold as the practitioner places pressure on the foot pedal control.
