There are basically two different techniques which are used by eye surgeons performing laser vision correction, LASIK (short for “laser assisted in situ keratomileusis”) and PRK (short for “photorefractive keratectomy”). For both these procedures, the laser is utilized in exactly the same way. The differences in the two procedures have to do with the way the cells of the surface of the cornea are managed by the surgeon, the rapidity of visual improvement, and the level of post operative comfort. With PRK the surface of the cells of the cornea are removed mechanically, and the corneal tissue just beneath the surface cells is treated with the same excimer laser. Although the PRK procedure itself does not hurt, patients can experience some postoperative discomfort and visual recovery is less rapid than with LASIK. PRK is an effective procedure, but it is generally utilized by Dr. Kandavel to treat patients who are not candidates for LASIK, such as individuals with thinner corneas. With LASIK the surgeon can use an ultra fast laser (Intralase laser) or a microkeratome to create a thin layer of the top portion of the cornea. The second laser treatment is performed beneath this thin corneal layer. The cornea layer is then gently repositioned over the surface of the cornea. The extraordinary natural bonding qualities of the cornea allow the effective healing to occur without using stitches. Dr. Kandavel only performs “all laser LASIK” there are no microkeratome blades involved whatsoever. Please see the “all laser LASIK” link for more information. While the LASIK procedure is more complex than PRK, and requires a higher level of skill by the surgeon, it is generally associated with very little, if any, postoperative discomfort and visual recovery begins almost immediately. Because of the increased level of comfort and the almost spontaneous visual improvement experienced by most patients, “all laser LASIK” is Dr. Kandavel’s preferred technique for patients who are appropriate candidates for the procedure.
