Clinical Trial of Cryotherapy Versus Postoperative Laser Photocoagulation

he cryopexy was performed by placement of a normal spherical probe under the bucklings, around the break. The number of cryo applications was limited in number of 3. Freezing was stopped at the beginning of retinal whitening.

Laser-retinopexy was performed after proper positioning the patients; laser energy was delivered by depressing a foot pedal. Short burn duration (0.1 seconds) and low (300-miliWatts) power settings were used initially, and both the burn duration and power were gradually increased as determined by observation.
