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). When the entire cornea is replaced it is known as penetrating keratoplasty and when only part of the cornea is replaced it is known as lamellar keratoplasty. Keratoplasty simply ...
Descemet membrane endothelial keratoplasty (DMEK) is a method of corneal transplantation that involves the removal of a thin sheet of tissue from the posterior (innermost) side of a person's cornea to replace it with the two posterior (innermost) layers of corneal tissue from a donor's eyeball.
In the case of the KeraKlear, the intralamellar pocket is created with a femtosecond laser or a corneal pocket making microkeratome. The posterior cornea is left intact. Typically, there is a follow-up session few days after surgery, when patients' complaints are addressed and modifications are made, if needed.

A corneal button is a replacement cornea to be transplanted in the place of a damaged, diseased or opacified cornea, normally approximately 8.5–9.0mm in diameter. [1] It is used in a corneal transplantation procedure (also corneal grafting) whereby the whole, or part, of a cornea is replaced. [2]
Tissue transplantation is a surgical procedure involving the removal of tissue from a donor site or the creation of new tissue, followed by tissue transfer to the recipient site. [ 1 ] [ 2 ] The aim of tissue transplantation is to repair or replace tissues that are missing, damaged, or diseased, thereby improving patients' survival ...

Contact lenses cause corneal neovascularization because they restrict oxygen diffusion to the corneal epithelium. In the short term, the cornea responds to oxygen deprivation by increasing blood flow to the corneal limbus, the narrow circular border between the cornea and sclera. Over time, this chronic limbal hyperemia can progress to corneal ...
