Undergoing surgery on eyes is not as easy as doctors say. First of all, we think of our eyes as being very delicate. And that's the reality. There are so many accidents that can cause, that everybody ought to carefully consider what clinic they choose to treat their sight.
PRK basically means photo-refractive keratectomy. The procedure implies the ablation of a small fraction from the cornea, resulting in reshaping it. In this way vision defects are corrected, permitting to give up the prescription glasses for a lot of people.
Lasik and PRK are in fact similar procedures, but the fraction removed from the cornea is not superficial, but a deeper portion. Then the upper portion of cornea is set in its original position, enabling the eye to start the healing process.
Lasik and PRK are both operated with excimer lasers. All lasers for PRK or for any other medical surgery must be FDA approved. This is how patients safety is secured. This is how the government is a signal they are preoccupied to have a healthy population.
Vision defects can be fixed through any of the two types of eye surgery. The physician will observe each candidate individually, then indicating one operation or another. Every now and then, they may even settle that the subject should not be exposed to any kind of eye surgery at all.
Faults in laser eye surgery may cost a lot, as they may impair the person who suffered the surgery irreversibly. Choosing doctors only after deeper research will diminish the risk of exposing ourselves to human errors from the medical staff.
Some surgeons say that patients heal faster after Lasik than after PRK. They may know what they are talking about, but there are no studies to support this evidence. Each patient is unique, so healing is a personal process. It can go well, but it also can go wrong. Only time can tell. - 16083
