![]() In the majority of treatments the buckle is left in place permanently, although in some instances the buckles can be removed after the retina heals. Scleral buckles are done using local or general anesthesia and are often done as outpatient procedures. The usage of scleral buckle is a source of debate only for complex retinal detachment surgery amongst surgeons, and research has been conducted to compare safety and effectiveness outcomes of scleral buckling, pars plana vitrectomy with scleral buckle versus pars plana victrectomy without scleral buckle. The laser or cryotherapy forms a permanent adhesion around the retinal break and prevents further accumulation of fluid and re-detachment. Retinal detachment surgery usually also involves the use of cryotherapy or laser photocoagulation. The physics or physiology of this process are not fully understood. This alteration in the relationships of the tissues seems to allow the fluid which has formed under the retina to be pumped out, and the retina to re-attach. ![]() This moves the wall of the eye closer to the detached retina. The scleral buckle is secured around the eyeball under the conjunctiva. Buckles are often placed under a band to create a dimple on the eye wall. A solid silicone grooved tyre element is also used. An encircling band is a thin silicone band sewn around the circumference of the sclera of the eye. A silicone sponge (with air filled cells) is a cylindrical element that comes in various sizes. Scleral buckles come in many shapes and sizes. Retinal detachments are usually caused by retinal tears, and a scleral buckle can be used to close the retinal break, both for acute and chronic retinal detachments. A scleral buckle is one of several ophthalmologic procedures that can be used to repair a retinal detachment.
