Minimal extraocular surgery is performed without drainage of sub-retinal fluid. As a result, the intraocular complications of drainage, such as hemorrhage, intraocular infection, incarceration of retina or vitreous, do not occur. In addition, the need for a subsequent intraocular injection of gas or saline to restore intraocular pressure with its complications is also eliminated.

Secondary glaucoma, cataract, or anterior ischemia did not occur, and because the procedure was extraocular, there were no iatrogenic breaks. Intraocular complications from cryopexy did not occur, because all applications were monitored by indirect ophthalmoscopy for a medium lesion (first appearance of white in the retina) [43]. There was a rare choroidal in highly myopic eyes.
