Similarities and differences of PRK and LASIK laser eye surgery
With the highly-developed technologies of vision treatments, people nowadays are opting to take laser eye surgery to treat their eye problems as laser surgery can take certain eye problems away completely. However, for most people, they just know two of the most common laser surgeries — PRK and LASIK, but they are confused what these eye surgeries actually are and which one is better. The following will give a brief introduction of PRK and LASIK on their similarities and differences in the hope of giving people some help on understanding of laser eye surgery.
PRK is short for Photorefractive Keratectomy. LASIK stands for the laser-assisted in situ keratomileusis. The similarities of them are they are both refractive eye surgeries. Compared with other surgeries, they are less risky. And for certain eye problems, they can move the problems away thoroughly.
The differences of both laser eye surgeries are as following: First, they use different ways to treat eye problems. PRK involves sculpting to change the surface of the eye. While LASIK uses the laser to treat myopia, hyperopia and astigmatism, a flap is cut on the eye to allow the laser to get behind to perform the remodeling instead of sculpting. Second, compared with LASIK, PRK is more risky. PRK makes use of PK procedure and radial keratotomy. It is realized by surgeons using scalpel to reshape the cornea. So we can see the surgeons’ experience also plays a role in it. Considering the pain and recovery time, LASIK is more excellent. LASIK is painless, while PRK is a little painful. And people with PRK laser eye surgery usually need more time to recover.
Therefore, when people consult in surgeons which laser eye surgery is better, surgeons generally recommend LASIK as it indeed has some outstanding advantages over PRK. But this does not mean all eye problems should be treated with LASIK eye surgery. That is because for some eye problems, PRK is the only option you can choose, which means LASIK can not work well with certain eye problems.
Above all, both PRK and LASIK have their own advantages and disadvantages. We can not say which one is definitely better. So before taking the laser eye surgery, it is advised to talk with your eye doctor. Then eye doctor will recommend the suitable surgery to you according to your eye problem, which will be good for treating your eye problem appropriately and effectively.
