First note use the word-component "kerato-"
as this refers to the cornea
(see also other 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 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
caled a lathe, then finally replaced 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, after full recovery from the procedure.
