Laser Eye SurgeryTypes of Laser Eye Surgery Laser procedures employ a special laser that corrects vision issues by reshaping the cornea, permitting you to regain correct targeting capabilities. As a consequence of laser eye surgery, most patients notice a remarkable improvement in their vision - actually, the bulk of them absolutely eliminate their dependency on corrective lenses. We'll provide you with info on laser eye surgery and laser treatment for eyes. Below is simply an helicopter view of the different areas concerned in this process. LASIK eye surgery is the most recent, most talked about form of laser surgery. It uses an excimer laser that performs the particular operation of reshaping the cornea to revive correct vision. This kind of laser has the facility to vaporise selected portions of the cornea without generating heat. The surgeon makes a tiny incision on the outer layer of the cornea to supply a flap. This flap is folded back out of the way whilst the laser makes the obligatory corrections to the underlying portion of the cornea. On completion of the laser processing, the corneal flap is repositioned, restoring correct vision just about instantly. The complete process takes just a few mins, it's almost painless, and it works wonders.Read plenty of informative articles on LASIK EYE SURGERY here. PRK eye surgery is different from LASIK in that it does all of its corrections to the outside layer of the cornea, thus it doesn't need the cutting of the cornea to produce the corneal flap. After removing a bit of the outer layer of the cornea, the laser turns its attention to the underlying area, reshaping it to fix vision defects. PRK laser eye surgery needs a longer healing time than LASIK, since a portion of the outer layer of the cornea has essentially been removed and must regrow. As a patient, you can potentially be needed to wear an eye bandage for 2 or 3 days for protection. In addition, PRK patients will most likely experience more discomfort in the healing process than LASIK patients. Why would any one need PRK rather than LASIK? PRK is really the best choice for certain patients. As an example, you may not be a good applicant for LASIK if your cornea is remarkably thin or if you have abnormally giant pupils. Your doctor will make the determination about which process is best for you on exam. LASEK is an altered version of the PRK process. LASEK uses a 20% alcohol solution to sofeten the outer layer of the cornea for easy removal. The major advantages of LASEK is a shorter healing time than PRK and no cutting is done as with LASIK procedures. Fundamentally the same as LASIK, except the laser is computer led, instead of being manipulated without delay by the surgeon. In an examination, your eye contour is mapped by a complex PC controlled system. The info gathered is then used to program the laser used in the precise LASIK process. Reports indicate the this technique is 25% more effective than prior LASIK systems. |
