LASIK vs Surface Ablation (PRK): Which Is Right for Your Eyes?

Medically reviewed by Dr. Fouad El Sayyad, Consultant Ophthalmologist — Cornea, Cataract & Refractive Surgery · Last reviewed: October 2026

Quick answer: LASIK and surface ablation (PRK) both reshape the cornea with an excimer laser to correct nearsightedness, farsightedness and astigmatism. LASIK works under a thin corneal flap, so vision recovers within one to two days with little discomfort. PRK treats the surface with no flap, so recovery is longer, but it is often safer for thinner corneas and contact sports. Long-term results are similar.

Key Takeaways

• LASIK and PRK give similar vision one year after surgery; the main differences are recovery speed and comfort.
• LASIK recovers faster and hurts less; PRK takes longer to recover and is uncomfortable for the first few days.
• PRK leaves more of the cornea untouched, which makes it the safer choice for thinner corneas, contact sports and some corneal surface conditions.
• The refractive screening at your clinic visit decides which procedure, if any, is safe for your eyes.
• Approximate prices for both eyes: PRK EGP 19,000–25,000; Femto-LASIK EGP 35,000–45,000.

What Is the Difference Between LASIK and Surface Ablation (PRK)?

Both procedures use the same type of laser (the excimer laser) to reshape the cornea. The difference is how the surgeon reaches the tissue that is treated. In LASIK, a thin flap is created and lifted, the laser treats the cornea underneath, and the flap is laid back in place. In PRK, the thin surface layer of the cornea (the epithelium) is removed, the laser treats the surface directly, and the surface layer grows back over a few days.

How Does LASIK Work?

I perform LASIK as Femto-LASIK. A femtosecond laser creates a thin, precise flap in the cornea, the flap is lifted, and the ZEISS MEL 90 excimer laser reshapes the cornea underneath according to your prescription. The flap is then returned to its place, where it seals without stitches. Both eyes are usually treated in one session of about 15–20 minutes.

How Does Surface Ablation (PRK) Work?

In PRK, the surface layer of the cornea is gently removed, and the excimer laser reshapes the cornea directly, with no flap or incision. A bandage contact lens is placed on the eye for about four to five days while the surface layer heals. Because no flap is created, PRK keeps more of the cornea’s strength, which is why it is often chosen for thinner corneas.

Which Recovers Faster, LASIK or PRK?

LASIK recovers faster. A Cochrane review comparing the two procedures found that LASIK gives faster visual recovery and is less painful than PRK, while vision one year after surgery is broadly similar.

• After Femto-LASIK: most people see clearly within one to two days and return to desk work within one to three days.
• After PRK: the first two to three days are uncomfortable, with watering and light sensitivity. Vision clears gradually over several weeks and keeps sharpening for up to 3–6 months.

For a day-by-day guide, see recovery time after LASIK.

When Is PRK the Better Choice?

• Your cornea is too thin to leave enough untreated tissue under a LASIK flap. How much tissue must stay untouched is judged for each eye from its thickness, shape and prescription.
• You play contact sports or work in a job with a risk of eye injury, such as the military or police.
• You have a corneal surface condition, such as recurrent erosion or surface irregularity, that PRK can treat at the same time.
• You have had previous eye surgery that makes a flap less advisable.
• A longer recovery is not a problem for your work or studies.

When Is LASIK the Better Choice?

• Your cornea is healthy and thick enough for a flap.
• You need to return to work or study quickly.
• You would prefer less discomfort in the first days after surgery.

If neither laser procedure is safe for your eyes, an implantable contact lens (ICL) or lens exchange may be considered instead. See LASIK requirements.

Are LASIK and PRK Equally Accurate?

Yes. Both procedures use the same excimer laser to reshape the cornea, and studies show similar visual results one year after surgery. LASIK is not more accurate than PRK; it is faster to recover from. The choice depends on your cornea, your lifestyle and how quickly you need to return to normal activities.

What Are the Risks of LASIK and PRK?

Serious complications are rare with both procedures when patients are carefully selected. Risks shared by both include:

• Dry eye: common in the first months and usually improves with lubricating drops.
• Night glare and halos: usually settle over three to six months.
• Under- or over-correction: in my practice, a second treatment (enhancement) is needed in fewer than 3% of patients with low myopia, up to about 10% with high myopia and 10–20% with hyperopia. Enhancement within the first year is free of charge.
• Corneal ectasia: rare progressive thinning of the cornea, prevented mainly by careful screening.
• Infection: very rare.

Specific to LASIK: flap problems such as folds or displacement after a direct blow to the eye. Specific to PRK: more pain in the first days and, rarely, a faint corneal haze that usually fades. See LASIK complications for details.

Who Should Not Have LASIK or PRK?

• People with keratoconus or a suspicious corneal scan.
• People whose prescription is still changing.
• Women who are pregnant or breastfeeding; wait at least one to three months after breastfeeding ends.
• People with an active eye infection, uncontrolled eye disease or certain autoimmune conditions.
• People taking isotretinoin for acne until it has been stopped for long enough.
• People with nearsightedness above about −10 diopters, for whom ICL is usually preferred.

How Much Do LASIK and PRK Cost in Cairo?

Approximate 2026 prices in my practice for both eyes are PRK EGP 19,000–25,000 and Femto-LASIK EGP 35,000–45,000.

PRK costs less mainly because it does not use a femtosecond laser to create a flap. Other factors that affect the price include the depth of the assessment before surgery, the laser technology used, the surgeon’s training and experience, the surgical facility, the follow-up visits, and imported supplies priced mainly in euros and US dollars. Your exact price is confirmed after a full eye examination. See LASIK price in Egypt.

What Patients Say About PRK (Google Reviews)

I had an absolutely fantastic experience at Al Sayyad Clinic. I underwent a PRK procedure with Dr. Fouad Al Sayyad, and everything went perfectly. The staff was professional, the environment was welcoming, and Dr. Al Sayyad’s expertise made the entire process smooth and comfortable. I highly recommend the clinic for anyone considering eye procedures.

Google review · Sayyad Eye Center, Mohandeseen

I had a PRK procedure at Sayyad Eye Center with Dr. Fouad El Sayyad. It was difficult for me to take the step of having vision surgery, but thank God, the center was more than excellent and the doctor was very excellent. Tonight it has been one month, and my vision is back to 6/6.

How Do I Choose Between LASIK and PRK?

The decision is made during the refractive screening at your clinic visit, which includes corneal tomography to map corneal shape and thickness, measurement of your prescription, eye pressure, a tear-film assessment and a retinal examination.

“I tell every patient that the most important part of the process happens during the refractive screening at your clinic visit. If your eyes are not safe for corneal refractive surgery, the right answer is to find another alternative, such as an ICL or lens exchange. And sometimes, not having surgery is the best option.”

Frequently Asked Questions

Which is better, LASIK or PRK?

Neither is better for everyone. LASIK recovers faster and is more comfortable in the first days. PRK takes longer to recover from but keeps more of the cornea’s strength, so it is often safer for thinner corneas and contact sports. Vision one year after surgery is similar with both. Your refractive screening decides which is right for you.

Is PRK more painful than LASIK?

Yes, in the first few days. After PRK, most patients have discomfort, watering and light sensitivity for two to three days while the surface layer heals, which is managed with drops, pain relief and a bandage contact lens. After LASIK, mild burning or watering usually lasts only a few hours.

Can vision reach 6/6 after PRK?

Yes, many patients reach 6/6 (20/20) vision after PRK, but the result depends on your prescription, your cornea and how your eyes heal. Vision clears gradually over several weeks and continues to sharpen for up to 3–6 months.

Which is better for a thin cornea?

PRK is usually the safer laser option for a thinner cornea because no flap is created. Enough untreated tissue must remain, and how much is judged for each eye from its thickness, shape and prescription. If even PRK would not allow a safe margin, an implantable contact lens (ICL) may be recommended instead.

Which is better for athletes or military and police applicants?

PRK is usually preferred for contact sports and jobs with a risk of eye injury, because there is no flap that could be displaced by a direct blow. If you are applying to a military or police college, check the current vision rules with the college itself before deciding on surgery.

Why is PRK cheaper than LASIK?

PRK does not use a femtosecond laser to create a corneal flap, so it involves fewer steps and less technology. Approximate prices in my practice for both eyes are PRK EGP 19,000–25,000 and Femto-LASIK EGP 35,000–45,000. The final price is confirmed after examination.

Can I have LASIK or PRK while pregnant or breastfeeding?

No. Hormonal changes during pregnancy and breastfeeding can change your prescription and affect healing. I recommend waiting at least one to three months after breastfeeding ends before measurements and surgery.

Can PRK be done after LASIK, or as a second treatment?

Yes. If a small prescription remains or returns, a second treatment (enhancement) can be done, sometimes as PRK on the surface of the cornea. In my practice, an enhancement within the first year is free of charge.
