In this eye surgery, a silicone band is sewn around the circumference of the sclera (the white part of the eye), right beneath the conjunctiva. This will bring the retina in close proximity with the wall of the eye, essentially reattaching the retina and closing the retinal tear, thus repairing the retinal detachment.
The surgery usually involves cryotherapy or laser. This is to form a permanent adhesion (“spot welding”) around the retinal tear to prevent re-detachment.
The scleral buckle is usually left in place permanently, although it can be removed if needed once the retina heals.
