Eye surgery is not as easy as doctors tell us. In the first place, we perceive our eyes as fragile. And this is the truth. So many people in the world are going blind, that one really has to be very careful what clinic they choose to have this surgery done.
PRK signifies photorefractive keratectomy. The procedure implies the the cutting of a small fraction from the cornea, resulting in reshaping it. In this manner myopia and hyperopia are corrected, making it possible to give up the prescription glasses for so many patients.
Lasik is working on the same principle as PRK, but the layer removed from the cornea is not superficial, but the next layer under the surface. Then the superficial layer is put back in place, permitting the eye to heal.
Both procedures are done with excimer lasers. All lasers for Lasik or for any other type of medical intervention have to be FDA approved. This is how patients safety is secured. This is how the state show they are preoccupied to have a healthy population.
Vision defects can be settled through any of the two types of eye surgery. The doctors will consult each candidate individually, then indicating one operation or another. Every now and then, they could settle that the subject should not be exposed to any kind of eye surgery at all.
Mistakes in laser eye surgery can be very costly, as they may affect the patients vision for ever. Choosing doctors only after thorough investigations will reduce the exposure to such medical risks.
Eye surgery professionals say that the eyes heal quicker after Lasik than after PRK. These doctors probably have their conclusions, but there’s hardly any medical proof to endorse this claim. Each of us is unique, therefore healing is a personal process. It can go well, but sometimes it could take very long. We’ll see as we live.
