A scleral buckle is one of several ophthalmologic procedures that can be used to repair a retinal detachment. 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. [citation needed] Scleral buckles come in many shapes and sizes.
Retinal detachment is a condition where the retina pulls away from the tissue underneath it. [ 1 ] [ 2 ] [ 3 ] It may start in a small area, but without quick treatment, it can spread across the entire retina, leading to serious vision loss and possibly blindness . [ 4 ]

[22] A scleral buckle is used in the repair of a retinal detachment to indent or "buckle" the sclera inward, usually by sewing a piece of preserved sclera or silicone rubber to its surface. [23]
Lattice degeneration is associated with retinal detachment, but the chance of developing retinal detachment if lattice degeneration exists is very low.. Lattice degeneration occurs in approximately 6–8% of the general population and in approximately 30% of phakic retinal detachments. [1]

The first hyaluronan biomedical product, Healon, was developed in the 1970s and 1980s by Pharmacia, [56] and approved for use in eye surgery (i.e., corneal transplantation, cataract surgery, glaucoma surgery, and surgery to repair retinal detachment). Other biomedical companies also produce brands of hyaluronan for ophthalmic surgery. [57]
