LASIK vs PRK vs ICL: Which Vision Correction Fits You?
Quick answer
LASIK and PRK both reshape the cornea with a laser. LASIK uses a thin flap and usually heals faster, while PRK has no flap and suits some people with thin corneas. ICL places a lens inside the eye and is often an option for higher prescriptions. An eye exam shows which one fits your eyes.
Key Takeaways
LASIK and PRK give similar results after about a year. LASIK usually means a faster, more comfortable recovery.
PRK can suit people with thin corneas or a very active lifestyle, because there's no flap.
ICL is often considered for higher nearsightedness, or when laser surgery isn't suitable.
None of the three stops the need for reading glasses that comes with age.
How LASIK, PRK and ICL Work
LASIK: A thin flap is made in the cornea, a laser reshapes the tissue underneath, and the flap is put back without stitches. LASIK is often considered for most people with nearsightedness, farsightedness or astigmatism.
PRK: The same type of laser reshapes the cornea, but there's no flap. The thin surface layer of the cornea is removed first, and it grows back over the following days.
ICL: No tissue is removed. A thin lens is placed inside your eye, in front of your natural lens, which stays in place.
LASIK or PRK?
LASIK and PRK use the same type of laser and, after about a year, give similar results. The main difference is the recovery. LASIK usually gives faster vision and is less painful in the first days. With PRK, discomfort usually peaks around the second or third day, and vision clears over days to weeks.

The recovery
PRK may be the better choice if your corneas are thin, or if you do contact sports or work where your eyes could be hit, because there's no flap that could move. Your eye surgeon recommends one based on your eyes.
When Is ICL a Better Fit?
ICL is often considered when your prescription is too high for laser surgery, or when your corneas are too thin for it. For moderate to high nearsightedness, research has found that lens implants such as ICL can give similar sharpness to laser surgery, and many patients prefer the quality of vision.
ICL is placed inside the eye, so it needs regular checkups over the years. ICL explains who it suits, the risks and the recovery.
Recovery Compared
LASIK: Burning or itching usually fades within hours, and most people take a few days off work.
PRK: Expect a few days of discomfort and about a week before you're back at work. A bandage contact lens protects your eye while the surface heals.
ICL: Your vision often improves within a day, and your eye takes several weeks to heal fully. LASIK and ICL explain recovery day by day.
What's the Same for All Three
You need a full eye exam first. It shows whether your eyes are healthy and which option suits them.
Your prescription should be stable, usually for about a year.
None of the three stops the need for reading glasses that comes with age.
You'll need checkups afterwards, so plan how you'll have them once you're home.
Questions to Ask Your Eye Doctor
- Which option do you recommend for my eyes, and why?
- Are my corneas thick enough for LASIK?
- How would my recovery differ with each option?
- Which option do you perform most often?
- What checkups will I need, and for how long?
LASIK vs PRK vs ICL: Frequently Asked Questions
Is PRK safer than LASIK?
Neither is safer for everyone. Both use the same type of laser and give similar results after about a year. PRK avoids the flap, which can matter if your corneas are thin or your eyes could be hit, while LASIK usually has a faster, more comfortable recovery. Your eye surgeon recommends one based on your eyes.
Can ICL be done if I'm not a candidate for LASIK?
Often, yes. ICL is one of the options when your prescription is too high for laser surgery, or your corneas are too thin. You still need to meet other requirements, such as a stable prescription and enough space in the front of your eye, which your surgeon measures during your exam.
