When your eyesight stabalizes you should get Photorefractive Keratectomy (PRK). PRK is a non-reversible surgical procedure in which the surgeon uses a laser to remove micro-thin layers of tissue from the cornea. The tissue is removed in a controlled pattern programmed into the computer by the surgeon.
When treating myopia, or nearsightedness, the surgeon uses the laser to flatten the corneal surface in a circular pattern. In comparison, when
treating astigmatism, the laser is programmed to remove tissue in an elliptical pattern, selectively reshaping some portions of the cornea to form a
smooth symmetrical surface. This procedure requires precise evaluation of the astigmatism so that the correct amounts of the laser energy are
delivered to the appropriate areas of the cornea. |
