Photorefractive Keratectomy (PRK) and Laser-Assisted in situ Keratomileusis (LASIK) are both vision correction procedures that can yield positive results for those persons needing to correct vision problems such as, near and far-sightedness (myopia and hyperopia respectively), and astigmatism.
There are similarities and differences with both options, and each have their pros and cons. Deciding on which option is best, is largely dependent on the patient being treated.
Similarities:
PRK is the predecessor to the more recent LASIK. It (PRK) is the first kind of laser eye surgery used to correct vision problems. Both these procedures work by reshaping the eye’s cornea through sculpting the stromal layer. This correction, in turn, allows the light that enters the cornea to be properly focused on the retina; thereby making one’s vision clearer. Both procedures are also very short in duration, taking only a few minutes per eye.
Differences:
The main difference between LASIK and PRK is how they access and treat the cornea. In PRK, the outer layer of the cornea is removed entirely. For LASIK a thin layer is created on the cornea. LASIK offers a faster recovery time than PRK.
Weighing the Pros and Cons
As stated earlier, each procedure has its advantages and disadvantages. Most of these lie in the post-op recovery period. LASIK generally offers a faster recovery time when compared with the recovery time of PRK. As a result, it takes longer to obtain improved vision post operation, if one opts for PRK. LASIK also offers the reduced risk of developing complications- such as haziness, infections, and inflammation subsequent to the operation. PRK is more suitable for patients with a thin cornea, and there is virtually no risk of having any corneal flap complications. The potential side effects of light sensitivity and night blindness are possibilities in both. That is why having a cornea specialist like Dr. Goosey is so important.
