Hi..... In Scleral buckling the surgeon treats the retinal tear with cryotherapy. Then the surgeon drains the fluid under the retina and sutures a specially shaped piece of silicone rubber to the outer wall of the eye...The silicone creates an indent, which closes the tear and holds it in place while the cryotherapy seal has time to form. The scleral buckle is permanent....
