A scleral lens is a prototypical lens dating back to the early 1880s. Originally these lenses were designed by using a substance to take a mold of the eye. Lenses would then be shaped to conform to the mould, initially using blown glass and then ground glass in the 1920s and polymethyl methacrylate in the 1940s. [ 7 ]
Posterior capsular rupture, a tear in the posterior capsule of the natural lens, is the most-common complication during cataract surgery. [8] Posterior capsule rupture can cause lens fragments to be retained, corneal oedema, and cystoid macular oedema ; it is also associated with increased risk of endophthalmitis and retinal detachment.
Scleral lens, with visible outer edge resting on the sclera of a patient with severe dry eye syndrome. A scleral lens is a large, firm, transparent, oxygen-permeable contact lens that rests on the sclera and creates a tear-filled vault over the cornea. The cause of this unique positioning is usually relevant to a specific patient whose cornea ...
Eye surgery, also known as ophthalmic surgery or ocular surgery, is surgery performed on the eye or its adnexa.

The scleral edge of the trepanation opening is heat-cauterized. [8] Additional deep scleral dissection can also be performed in the scleral bed with trabeculectomy, first introduced by T. Dada et al.; [9] deep scleral excision is performed in non-penetrating filtering surgeries but not traditionally in trabeculectomy. The space created from the ...

Scleral reinforcement surgery is not presently popular in the United States, and there has been a scarcity of published clinical studies. Donor sclera material is also difficult to acquire and store, and artificial materials are still being tested. This procedure is much more popular in other countries, such as the former Soviet Union and Japan ...
[4] [5] This technique was further modified by making scleral flaps and creating scleral pockets for tucking the haptics. The flaps are then reattached to the bed with the help of glue. On 14 December 2007, the first glued intraocular lens (IOL) surgery was performed, at Dr. Agarwal's Eye Hospital in Chennai, India.
