Two Good Procedures, One Right Fit
Both use the same laser to reshape the front window of your eye (the cornea) so light focuses properly and you depend less on glasses or contacts. The real difference is how the surface of the eye is treated and how you heal afterward.
This short guide is for anyone weighing the two. My goal is simple: by the end you will understand what each one is, why PRK is a genuinely good choice for some eyes, and why the final decision always comes down to your own assessment.
What Each Procedure Actually Does
With LASIK, I create a thin hinged flap in the cornea, reshape the tissue underneath, and then lay the flap back down where it settles into place on its own.
With PRK, there is no flap at all. I gently move aside that thin outer skin, reshape the tissue directly on the surface, and let the skin grow back naturally over a few days.
A simple way to picture it: LASIK is like lifting a small trapdoor to work underneath, then closing it. PRK is like polishing the surface directly and letting a fresh, smooth layer regrow. Same laser, same goal, different path to get there.
PRK Is a Choice, Not a Consolation Prize
I want to be clear about this because it worries patients: being offered PRK does not mean something is wrong with you or that you are getting a downgrade. PRK was the first laser vision correction procedure approved, and it has been correcting eyesight reliably since the late 1980s. For the right eye, it can be the safer and smarter option, not a fallback. The reason most people end up with LASIK is the faster, more comfortable recovery, not a better final result.
Did You Know?
Many professional pilots and military special forces are required to have PRK rather than LASIK. Because PRK leaves no corneal flap, there is nothing that could be affected by sudden pressure changes, ejection forces, or impact. For these high-stakes careers, the flapless procedure is considered the more robust choice.
When to Call Us Right Away
Some soreness, watering, light sensitivity, and blurry vision are expected after surgery, especially with PRK in the first few days. But certain signs are not normal and need prompt attention. Contact us or seek urgent eye care without delay if you notice: - Sudden or worsening eye pain that your drops do not ease - A noticeable drop in vision after it had started improving - Increasing redness, swelling, or thick discharge from the eye - A sense that something hard hit or scratched your eye, or that the surface feels displaced (especially relevant after LASIK) - Flashes of light, a shower of new floaters, or a shadow or curtain across your vision When in doubt, call us rather than wait. It is always better to check early.
An Honest Word on Risks and Candidacy
Not every eye is a candidate. Your cornea may be too thin, your prescription outside the safe range, or your eyes too dry, and some health and eye conditions rule it out. That is exactly what the assessment is for. The measurements decide, not the marketing. If you are not a good candidate for either procedure, I will tell you honestly and talk you through other options.
Let's Find the Right Fit for Your Eyes
The choice between LASIK and PRK is not about which one is better in general. It is about your cornea, your lifestyle, and how much recovery time you can spare. The only way to know which suits you is a proper assessment. If you are considering laser vision correction, book a consultation with me, Dr. Tamer Salem, at Spanish Center Dubai. I will measure your eyes precisely, walk you through your options in plain language, and recommend honestly the procedure that gives you the best long-term result, even if that means waiting or choosing neither.
