laser eye surgeryy?

I’m considering getting laser eye surgery and was looking for some advice.

Anyone who is likely to suffer ocular trauma, such as a boxer, should seriously consider the surface ablation techniques PRK, LASEK, or Epi-Llasikover Lasik or All-Laser Lasik. The reason is the Lasik flap.

The first step of Lasik is to create a thin flap of corneal tissue 100-180 microns thick. The flap is moved aside, the laser energy is applied to the cornea, and the flap is repositioned over the treatment area. By applying the laser energy deeper in the cornea under the Lasik flap, the eye is “fooled” into not realizing it has had surgery. This mutes the wound response to provide faster vision recovery and virtually no pain.

Although the Lasik flap does heal, it does not heal like a scratch on your arm. The cornea is always different at the location of the incision. The flap is secure, but trauma or a scraping motion across the cornea can dislodge the flap.

PRK, LASEK, and Eplasekik do not create the Lasik flap. The “flap” with LASEK and Epi-Lasik is actually only corneal epithelial cells. These cells are mortally wounded during surgery and are quickly replaced with new cells.
