What does LASIK mean?

LASIK is the acronym for laser in situ keratomileusis. The name refers to the use of a laser to reshape the cornea without invading the adjacent cell layers. In situ is Latin for "in the natural or normal place". Medically, in situ means "confined to the site of origin without invasion of neighbouring tissues". Kerato is the Greek word for "cornea" and mileusis means "to shape".
