Laser eye surgery is one of the best options for people who have vision errors, but do not want to wear glasses or lenses. It can offer great vision clarity and many receivers have gained 20/20 vision after getting it. Everything will be fine within very short time via simple procedure.
Of course, laser eye surgery can be fallen into several types, according to receiver's needs and the technology employed in the surgery. For example, Photorefrative Keratectomy (PRK) and Laser Assisted Sub-Epithelial Kertaomileusis( LASEK), are two typical laser eye surgeries. The two share something in common, but there is still some difference.
Some numbing drops will be used in the two procedures. While operating, patients can know what happen to their eyes. And patients should have a good rest after the surgery if they want to make sure that their eyes can heal quickly with greater safety.
One of the greatest differences between the two procedures is the way to treat cornea. In the PRK, some of the cornea surface will be scraped, so as to allow the laser remove some extra tissues in the cornea. In LASEK, a flap will be made on the surface of the cornea. In each of the two surgeries, how much to be removed is determined by patient's personal situation. After the surgery, the cornea will be left to grow gradually.
And now laser surgery can be used to rectify many vision problems, from the simplest to the most serious. Of course, these surgeries are relatively expensive and can not be afforded by all people. If people want to get it, some preparations are needed. For example, a qualified surgeon is needed.
Or in other cases, these surgeries can be used to treat blindness and many other horrible problems. Anyway, laser eye surgery is one of the most effective and simplest ways to rectify vision errors of many kinds permanently.
