PRK or LASIK? Find out What’s Better for you between the Two

What is the difference between PRK and LASIK? Which procedure has a higher success ratio and lesser complications? What is best for me? These are some of the most common questions asked by patients contemplating a refractive vision correction. Given the excellent outcomes and faster recovery of these painless vision correction procedures, both PRK and LASIK have become very popular among people wanting to get rid of vision problems like astigmatism, nearsightedness and farsightedness. An informed decision is the key to a successful surgical outcome so let’s compare the two procedures and help you weigh your options and make a wise decision.

Differences between LASIK and PRK

  • Both PRK and LASIK are minimally invasive eye surgeries typically recommended to patients suffering from visual impairments.
  • Both the surgeries are treated as out-patient procedures not exceeding 15-20 minutes.
  • The only major difference between each surgery is the way in which the cornea is reshaped.
  • PRK surgery does not involve the creation of a flap so the underlying layers of the cornea are preserved while in LASIK the patient’s epithelial cells remain intact.

Pros and Cons of LASIK vs. PRK

  • Since PRK does not involve the creation of a flap, it has zero possibilities of flap complications during or after the surgery
  • Corneas that are too thin for a LASIK surgery can be reshaped with a PRK procedure
  • Patients experience more discomfort following a PRK procedure as compared to a LASIK surgery
  • The risk of eye infection is higher after PRK surgery when compared with LASIK
  • A person undergoing PRK surgery has a much thicker stromal bed residual after the excimer laser correction.

Which is better?

With the advances in laser technology, LASIK is the favored surgical treatment especially for patients with a thick cornea. The post-operative discomfort is much lesser, recovery is much faster, and patients can go home with much less discomfort. While LASIK does offer the advantage of excellent vision, the very next day after the surgery, the incidence of dry eyes and the risk of flap complications are both high with a LASIK procedure.

So what is the best for you? If you have suffered from dry eyes, have a history of abnormal topography or have a thin cornea, you would benefit with a PRK procedure. Both the procedures are safe, effective and have a high ratio of success so choosing between the two is a decision best made by consulting an experienced eye surgeon who specializes in laser-assisted eye procedures.
