Photorefractive Keratectomy

PRK, or photorefractive keratectomy, is one of the first eye developed repair procedures. During this procedure the top layer of cells covering the cornea, epithelial layer, carefully removed. After the surgeon removed the cell layers using the Excimer laser to shape the cornea. How much corneal tissue is removed for re-formation process depends on how bad the man's eyes. PRK differs from LASIK procedure in the corneal flap is not created, so the lack of change in the cornea during PRK surgery. This surgery is often used in people who can not get LASIK because they have very thin corneas.

Custom Wavefront LASIK uses some of the latest technology to improve procedures for corrective eye surgery. Types of procedures using Wavefront technology to adjust the correction procedure LASIK someone. The advantage of this technology is that patients can have their corneas mapped down to the smallest detail. The surgeon then can achieve a better level of correction when the cornea is reshaped. Wavefront LASIK results reported improved quality of vision, decreased night vision difficulties, and reduction in halos and glare. The procedure used to correct corneal LASIK surgery as the original.

Epi-LASIK is the advanced LASIK procedure was developed to overcome some problems that arise from the LASIK procedure. Original LASIK corrects the cornea by cutting the corneal flap in itself, this procedure can sometimes cause visual disturbances such as halos, and people with thin corneas who can not undergo regular LASIK procedure. Epi-LASIK is a procedure that corrects vision by lifting the top layer of corneal epithelial tissue, the cornea is sculpted. No flap in the cornea is produced, and the epithelial layer grows back within 3-5 days. Epi-LASIK procedure can be performed in patients with thin corneas and patients with high myopia.

Lasek, or Laser-Assisted Sub-epithelial keratectomy, is the eye correction procedure performed since 1996. This procedure was developed from PRK and LASIK procedures, and was created in order to overcome the complications and problems arising from PRK and LASIK procedures. Lasek Procedure using trephine blade solutions smooth 20% alcohol and gently lift the top layer of surface epithelial layer and fold back the eye. cornea is then reshaped with the Excimer laser, and the epithelial layer is put back and left to heal. PRK procedure does not protect epithelial layer, and the LASIK procedure uses a thicker blade to cut deeper into the cornea.

IntraLase "Bladeless" eye surgery is a corrective eye surgery that uses a laser instead of a knife, to create a flap in the cornea. Corrective eye surgery 'Bladeless' is a technique available at this time. IntraLase laser works by creating a small layer of bubbles just below the surface of the cornea, this layer of bubbles allow the surgeon to gently lift the lid back without using a knife, and then the cornea is reshaped. flap was folded back after surgery and left to heal. Bladeless IntraLase procedure reduces the likelihood of complications that can occur from cutting into the cornea.

Presby LASIK, also known as Multifocal LASIK, eye correction is a procedure used to treat the eye condition called presbyopia. Presbyopia is a condition that usually occurs in people between 40 to 50 years. This condition is characterized by the inability to focus at all distances; multifocal glasses used in these cases to improve vision. Presby LASIK procedure uses a laser to reshape the eye into the design that works like a multi-focus lens. 'Peak' is often left on the cornea, and then gradually flat side. The end result is the ability to focus on near and far distance at the same time. This procedure has not been approved by the FDA, the only way to receive the Presby LASIK in the United States is to join a clinical trial.
