A radial keratotomy is a surgical procedure
on the cornea
of the eye.
This is implied by the term "radial keratotomy" because the part "kerato-" refers to the cornea, as is also true of other terms in this section (listed on the left), and the part "-otomy" usually indicates "cutting", "dividing", or "separating" the specified body-part, component, or type of tissue.
A radial keratotomy, is a surgical operation to treat short-sightedness (myopia). During this procedure, deep cuts called "incisions" are made into the tissue of the cornea of the eye. These cuts are made radially around the outer two-thirds of the cornea of the eye in order to flatten the curvature of the central part of the cornea. This procedure has been used for milder, rather than more severe cases of myopia. In many cases it is now being replaced by excimer laser treatment.
Patients can generally obtain information about this, and other procedures, from their ophthalmologist (ophthalmic surgeon).
