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 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 also driven by excimer laser action like PRK, but the fraction removed from the cornea is not superficial, but a deeper portion. Then the superficial layer is set in its original position, permitting the eye to start the healing process.
Lasik and PRK are performed with excimer lasers. All lasers for eye surgery or for any variant of medical intervention have to be FDA approved. This is how patients safety is secured. This is a measure the state indicate they are preoccupied to have a healthy population.
Myopia and hyperopia can be corrected through either Lasik or PRK surgery. The doctors will examine each person individually, then indicating one operation or another. Every now and then, they could indicate that the patient should not be performed neither operation onto.
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.
