If you have been told you cannot have LASIK, you might think you cannot have laser eye surgery at all. Fortunately, PRK (Photorefractive Keratectomy) is available for many people who are not good LASIK candidates. This procedure has a longer recovery time than other types of laser vision correction but has its own benefits.
PRK, a form of laser eye surgery, uses a laser to change the shape of your corneas. The corneas are clear structures at the front of the eye that bend light. PRK changes the angle of light to improve your vision. The actual laser reshaping works the same way in PRK and LASIK, but the way of creating access to the middle layers of the cornea is different.
During PRK, your eye surgeon will numb your eyes. They will then remove the outer layer of the cornea (the epithelium). This painless step allows your eye surgeon to use a laser to remove microscopic layers of the cornea until the necessary degree of correction has been achieved. Your eye is then covered with a contact bandage that protects your eye until your surgeon removes it at a follow-up visit.
While PRK might not be the ideal procedure for everyone, it is an excellent option for the right person. Only an eye exam and consultation can determine whether your eye surgeon recommends PRK. Benefits of this procedure include:
The biggest benefit of PRK is that it does not create a flap in the corneal epithelium like LASIK does. Instead, the entire epithelium will regrow intact. While a LASIK flap can become disrupted, the epithelium that regrows after PRK is as strong as the original.
PRK offers the most significant benefits for people who are not good candidates for LASIK. It provides the same dramatic vision improvements that LASIK can achieve but with a longer recovery time.
People considering PRK should have healthy eyes with no signs of cataracts. Good candidates may be farsighted, nearsighted, or have astigmatism. Unlike LASIK, PRK is more forgiving in eyes with thin or abnormally shaped corneas. It is also suitable for those who play contact sports. Candidates should be eighteen years old or older and have a stable prescription.
You can expect some blurriness, irritation, and sensitivity for a few days after your procedure. Most people can see significantly more clearly after three to five days. You will have several follow-up exams so your eye surgeon can make sure your corneas are healing normally. Most people achieve optimal results within about a month. Once healed, your corneal surface is stable and cannot be disrupted.
