LASER EYE SURGERY This research paper investigate

The future of ophthalmology includes the increased usage of laser eye surgery for the prevention and cure of many eye conditions, as well as the replacement of conventional eye surgery for safer and more effective results. For example, by the year 2020, it is predicted that blindness will affect 90 million people, and glaucoma is one leading cause of blindness. Argon laser trabeculoplasty is reported to be safe and effective for initial therapy of primary open-angle glaucoma, resulting in reduction in intraocular pressure and improved visual fields and acuity. Laser screening for retinal disease leads to early detection and improvement in patient prognosis; this screening has allowed for the establishment of efficacy of laser photocoagulation surgery for the notable prevention of visual loss. Refractive surgery, initially done with conventional surgical techniques, now being rapidly and successfully replaced with laser technology, will be the focus of this report (ADA, 2000, p. S73; Frankel, 1995, p. 1699; Jones, 1999, p. 1303; Thylefors, 1999, p. S44).

Replacement of Conventional Eye Surgery

crokeratome cutting of a hinged corneal flap. For this procedure, a flap is cut from the cornea front and PRK is used beneath it. The flap is then replaced and it reseals without stitches. LASIK was introduced to help minimise haze resulting from PRK procedures, however complications can occur due to the flap (Armstrong, 1998, p. x; Jory, 1996, p. 904). London Place Eye Centre (LPEC) uses a no touch laser vision correction procedure. This technique allows for the removing of the epithelium of the cornia, with the laser. Other methods for removal of the epithelium for PRK include scraping it off with a scalpel, using a circular rotating brush, soaking it in alcohol, wiping and lifting it off, or using the laser to remove 90% of it and scraping the rest off. Use of the laser for removal, in the no touch procedure, is less traumatic, results in a very smooth surface, and more rapid regrowth (LPEC, 2000d, p. 1). What Type of Laser Would Work Best? London Place Eye Centre (LPEC) uses the Broad-Beam laser (VISX) with a multi-pass, multi-zone technique, and the Scanning laser (NIDEK) for their no touch laser vision correction procedure (LPEC, 2000d, p. 1). The Nidek Excimer is used for hyperopic treatment, it allows for the
