Manual small incision cataract surgery (MSICS) is an evolution of extracapsular cataract extraction (ECCE); the lens is removed from the eye through a self-sealing scleral tunnel wound. A well-constructed scleral tunnel is held closed by internal pressure, is watertight, and does not require suturing.
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. [ 6 ]
[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.

A temporary ocular conformer is inserted at the completion of the pro- cedure and is worn until the patient receives a prosthesis 4 to 8 weeks after surgery. An elective secondary procedure is required to place the coupling peg or post in those patients who desire improved prosthetic motility.
Eye surgery, also known as ophthalmic surgery or ocular surgery, is surgery performed on the eye or its adnexa. [1] Eye surgery is part of ophthalmology and is performed by an ophthalmologist or eye surgeon. The eye is a fragile organ, and requires due care before, during, and after a surgical procedure to minimize or prevent further damage.
Two partial thickness scleral flaps measuring 2.5 to 2.5 mm are made 180 degrees diagonally apart. Infusion is placed by anterior chamber maintainer and sclerotomies are made below the flaps with 20 gauge needle. The IOL is injected below the remaining lens particles and the remaining lens is positioned on the artificial lens or IOL (Fig 2).
After being used regularly for centuries, couching has been mostly abandoned in favour of more effective techniques, due to its generally poor outcomes, and is currently only routinely practised in remote areas of developing countries. [11] [12] Cataract surgery was first mentioned in the Babylonian code of Hammurabi 1750 BCE. [13]
