Supporting surgical vision correction is not as easy as ophthalmologists tell us. In the first place, we believe our eyes as extremely sensitive. And this is the truth. There are so many accidents that can cause, that everybody ought to carefully consider what hospital they choose to correct their sight faults.
PRK is nothing more than photo-refractive keratectomy. The surgery is basically the ablation of a small fraction from the ocular cornea, resulting in reshaping it. In this way sight faults are corrected, making it possible to give up the prescription glasses for so many people.
Lasik does pretty much the same as PRK does, but the layer removed from the cornea is not superficial, but a deeper portion. Then the upper portion of cornea is put back in place, enabling the eye to cure itself.
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.
Sight faults can be corrected through either Lasik or PRK surgery. The surgeon will consult each patient individually, then indicating one operation or another. Chances are, they just indicate that the subject should not be performed neither operation onto.
Human errors in laser eye surgery can be very costly, as they may impair the person who suffered the surgery irreversibly. Deciding for the eye surgeon only after informing yourself very well will reduce the peril of a wrongly applied procedure.
There are doctors who tell that patients heal quicker after Lasik than after PRK. These surgeons may be right, nonetheless there's hardly any medical proof to backup this fact. Each of us is unique, thus healing is a personal process. It could be rather fast, but there are times when it goes slowly. This will become evidence as time passes. - 20765
