What does LASIK mean?
LASIK is the acronym for laser in situ keratomileusis, sometimes referred to as laser assisted 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 Greek 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”.
LASIK is an acronym for laser assisted in-situ keratomileusis. It’s a surgical procedure in which an excimer laser beam works within your eye’s corneal tissue under a protective flap to “reshape” the cornea, thereby changing where images focus on the retina. Many common vision problems, such as farsightedness and nearsightedness, occur because of the length of the eye or the shape of the cornea, which prevent the images from focusing on the retina in the correct place.
