Phacoemulsification: Phacoemulsification refers to modern cataract surgery in which the eye’s internal lens is emulsified with an ultrasonic handpiece and aspirated from the eye. Aspirated fluids are replaced with irrigation of balanced salt solution, thus maintaining the anterior chamber, as well as cooling the handpiece.

Endothelium- The endothelium is the thin layer of cells that lines the interior surface of blood vessels,[1] forming an interface between circulating blood in the lumen and the rest of the vessel wall. These cells are called endothelial cells. Endothelial cells line the entire circulatory system, from the heart to the smallest capillary. These cells reduce turbulence of the flow of blood, allowing the fluid to be pumped farther.

Keratoplsty Corneal transplantation, also known as corneal grafting, is a surgical procedure where a damaged or diseased cornea is replaced by donated corneal tissue (the graft) in its entirety (penetrating keratoplasty) or in part (lamellar keratoplasty). The graft has been removed from a recently deceased individual with no known diseases or other factors that may affect the viability of the donated tissue or the health of the recipient. The cornea is the transparent front part of the eye that covers the iris, pupil and anterior chamber. The surgical procedure is performed by ophthalmologists, medical doctors who specialize in eyes, and is often done on an outpatient basis. Donors can be of any age as was Janis Babson, who donated her eyes at age 10.

Descemet’s membrane is the basement membrane that lies between the corneal proper substance, also called stroma, and the endothelial layer of the cornea. It is composed of a different kind of collagen (Type VIII)[1] than the stroma. The endothelial layer is located at the posterior of the cornea. Descemet’s membrane, as the basement membrane for the endothelial layer, is secreted by the single layer of squamous epithelial cells that compose the endothelial layer of the cornea.

Its thickness ranges from 3 μm at birth to 8-10 μm in adults.[2]

It is also known as the Posterior limiting laminaposterior elastic laminalamina elastica posterior, and membrane of Demours. It was named after French physician Jean Descemet (1732–1810).
