The gift of sight is something that should never be taken lightly. To be able to see the sky, watch a ball game, read a book or picture the expression of the faces of your loved ones, is something that we should never take for granted. There are people who have had this gift taken from them, usually for reasons of health and the only way that they can now access these images is through their memory.
Thankfully in the last few years, technological innovations in laser surgery have made it possible to dramatically improve a personís failing eye sight, and bring it back to a normal level, often without the need for eye glasses. This modern miracle is carried out through the wonders of laser surgery. Laser surgery is highly effective, with almost faultless rates of success and is totally non invasive. Laser eye surgery is painless and the effects of the operation are instantaneous. Modern laser surgery is carried using the same equipment, but employing one of either two techniques.
The first known as Photorefractive Keratectomy or PRK for short, involves ablation of the cornea, which is a form of laser driven light scraping of the cornea, to remove the part of the defective lining, which is affecting the eyesight. Once the defective lining has been removed, a new and healthy lining will form gradually but within a relatively short time and the patientís eye sight will return to full strength. The second, and more widely used procedure is known as ďlaser assisted in situ keratomileusisĒ or LASIK for those who canít get their tongue around the expression.
When the LASIK technique is used, the eye surgeon removes the topmost layer around the damaged cornea. Most people are unaware of the fact that the type of exceptionally delicate and accurate laser beam used in this procedure, known as the Excimer beam, actually disintegrates the faulty lining. Once this is done, the recovery procedure is down to the forces of nature, which will then allow new corneal tissue to grow in place of the damaged tissue. Corrective laser driven eye surgery is within all our grasps and this breakthrough in medical science is there to be taken advantage of.
