Key Takeaways
- Both LASIK and PRK reshape the cornea to correct vision, but use different methods.
- LASIK often has a faster recovery, while PRK recovery can take 1 to several weeks.
- PRK may suit people with thin corneas or active lifestyles with higher eye injury risk.
- LASIK carries a higher dry eye risk while PRK avoids flap-related complications.
- An eye exam with an Orillia optometrist can help determine which option fits your eyes.
If you need glasses or contact lenses to see, you’ve probably considered laser vision correction before. Being less reliant on your glasses sounds appealing, and when you start researching, 2 names keep coming up: LASIK and PRK. Our team offers laser eye surgery consultations to help you decide which may be a good option for you.
Both LASIK and PRK reshape the cornea to correct vision, but they do so differently, have different recovery timelines, and suit different eyes. Knowing those differences can help you ask the right questions during your consultation at Orillia Optometry.
How LASIK and PRK Work
Your cornea is the clear dome at the front of your eye. Both LASIK and PRK use a laser to gently reshape that surface so light lands where it should.
The key difference is how the eye surgeon accesses the cornea. LASIK involves creating a thin flap in the outer layer, reshaping the tissue underneath, and folding the flap back into place.
PRK skips the flap entirely. Instead, the outer layer of the cornea is removed before the laser reshapes the surface. That outer layer grows back naturally over the following days.
What Each Procedure Involves
The LASIK Process
Numbing drops go in first, so you shouldn’t feel pain or discomfort during the procedure. The eye surgeon will then create a thin flap in your cornea, fold it back, and reshape the tissue underneath with a laser. The flap is then placed back into position, where it bonds without stitches.
The whole procedure typically takes about 30 minutes, though everyone is different.
The PRK Process
PRK also starts with numbing drops. The difference is that the outer corneal layer, called the epithelium, is removed before the laser does its work. Once the cornea is reshaped, a bandage contact lens is placed over the eye to protect it while the surface heals.
Both eyes typically take around 15 minutes total. The procedure itself is short. It’s the recovery that takes more time.
Recovery Time and What to Expect
LASIK Recovery
LASIK recovery often happens quicker. Some people notice clearer vision within hours, and many can return to their normal routine the next day. You might experience mild discomfort or light sensitivity for a day or 2, but this tends to settle quickly.
PRK Recovery
PRK takes longer to heal because the outer corneal layer needs time to grow back. Full recovery can range from 1 to several weeks, and during that time, you may notice blurriness, soreness, or sensitivity to light. These are normal parts of the healing process, but always listen to your eye care team about what to watch for.
The bandage contact lens often comes out after a few days, usually at a follow-up appointment. As the surface of your eye begins to heal, you may notice that your vision gets clearer.
Who Is a Good Candidate for Each?
When to Consider LASIK
LASIK may be a good fit for those with average to thicker corneas, since creating the flap requires enough tissue depth. If a faster return to normal activities is a priority for you, the quicker recovery timeline of LASIK is worth considering.
When to Consider PRK
PRK is often a better fit when LASIK isn’t possible or advisable. Your eye care team may recommend PRK in situations like these:
- Your corneas are thin or have an irregular shape
- You play contact sports or work in a setting where an eye hit is possible
- You already have symptoms of dry eye
Because PRK doesn’t create a flap, there’s nothing that can shift or get dislodged if your eye takes a knock. For those with very active lifestyles, that’s worth considering.
The Tradeoffs of Each Procedure
Neither option is without considerations. PRK comes with a longer recovery, more temporary discomfort, and a stretch of light sensitivity that can feel frustrating to some people. LASIK carries a higher chance of dry eye symptoms after surgery, and there’s a small possibility of flap-related complications, though these are uncommon.
These risks are low, but your eye care team will go over them with you so you’re fully informed before you commit to an option. A thorough eye exam gives a clearer picture of which procedure may fit your eyes and your life.
