If you are considering undergoing eye surgery, you have most likely spent the majority of your time researching Lasik. This is because Lasik is the only refractive vision correction surgery in town, right? Wrong! In fact, there are numerous cases where another eye surgery (such as Photorefractive Keratectomy or PRK) would be more ideal. This article, is going to compare PRK and lasik.
Of course, you may be wondering why Lasik would not be ideal for everyone. The main reason has to do with the prospective patient’s corneas. If their corneas are too thin or have been damaged before, it is impossible for an eye surgeon to create the corneal flap that Lasik requires.
Now that you know the circumstances in which PRK would be more preferable than Lasik, let’s lookinto a little more detail about the PRK surgery.
During PRK surgery, the eye surgeon uses a laser to get the eye to reshape itself. This reshaping is what causes the patient’s vision to improve. This is because the result of the reshaping is the refocusing of light on the patient’s retina.
Now that we have defined the theory behind PRK, let’s see how it is applied. During the actual surgery, the surgeon uses the laser to vaporize a portion of the cornea’s epithelial cells. Once these have been removed, the surgeon then uses the laser to vaporize a portion of the black part of the eye (which is referred to as a stoma). After he or she does this, the surgery is over.
After the surgery, the eye will then begin healing itself by creating a new layer of epithelial cells to repair the area where PRK was performed. Usually, it will take around a week for these new cells to be created.
