Intrastromal keratomileusis is an ophthalmic surgical operation used to treat some severe cases of short-sightedness (myopia).
The word-component "kerato-" refers to the cornea (see also other similar terms in this section - listed on the left). The cornea of the eye consists of both its stroma (which is its connective tissue basis, i.e. the transparent fibrous tissue that forms the main body of the cornea) and its functional tissue (which is called the parenchyma).
The intrastromal keratomileusis procedure involves removal from the eye of a disc of tissue from the stroma of the cornea, which is then frozen, remodelled (i.e. shaped) using a piece of mechanical equipment called a lathe, then finally replaced back into the cornea. The purpose of these steps is to re-shape the cornea to reduce the extent of short-sightedness experienced by the patient.
There is now a laser treatment alternative to this surgical procedure.
