ophthalmology
PRK is a refractive laser eye surgery in which the corneal epithelium is removed and an excimer laser reshapes the underlying corneal stroma to correct myopia, hyperopia, or astigmatism. PRK predates LASIK and remains the preferred surface-ablation technique for patients with thin corneas, occupational requirements that contraindicate a corneal flap (military, contact sports), or borderline topography that makes a flap risky. Recovery is slower and more uncomfortable than LASIK because the epithelium has to heal over the treated cornea — typically 3-5 days with a bandage contact lens — but biomechanical integrity of the cornea is preserved.
Photorefractive keratectomy (PRK) is a laser eye procedure that permanently changes the shape of the anterior central cornea in order to reduce a person's dependence on glasses or contact lenses. It is a surface-ablation technique: rather than cutting a corneal flap, the surgeon first removes the cornea's outer layer — the epithelium — before an excimer laser ablates (vaporises) a small amount of tissue from the underlying corneal stroma. The epithelium is a soft, rapidly regrowing layer in contact with the tear film, and it can completely replace itself from limbal stem cells within a few days without loss of clarity; the deeper corneal layers, once reshaped, remain that way permanently with only limited remodelling. During treatment a computer tracks the patient's eye position many times per second — from roughly 60 to several thousand times, depending on the laser — and redirects laser pulses for precise placement, automatically centring on the visual axis and pausing if the eye moves out of range. Several variants exist, including alcohol-assisted PRK, transepithelial PRK (TransPRK) and advanced surface ablation (ASA) LASEK, which uses an Amoils brush and gas cooling to reduce discomfort. Because the epithelium is removed and discarded so that the cells can regenerate after surgery, PRK typically involves a slower and more uncomfortable early recovery than flap-based LASIK, but it preserves more of the cornea's underlying structure.
PRK is typically priced 10-20% below LASIK at the same clinic due to lower equipment cost (no femtosecond flap creation). Quoted prices usually cover pre-operative topography and pachymetry, the procedure, the bandage contact lens, and short-term follow-up. Mitomycin C application may be a small additional charge in some markets. Enhancement procedures (typically allowed within 12-24 months) may be free or discounted depending on the clinic's policy.

Average recovery for PRK (Photorefractive Keratectomy) is 7 days. Individual recovery varies — always follow your surgeon’s specific guidance.
Immediate
First 24–48 hours post-procedure. Monitoring, anaesthesia recovery, initial pain management. Most clinics expect you to remain on-site or nearby.
Early recovery
Wound care, swelling or bruising peaks, restricted activity. Typical window for follow-up visits and drain removal if applicable. Travel is usually not advised.
Intermediate recovery
Gradual return to non-strenuous daily activity. Many international patients fly home during this window. Surgeon may require medical clearance for long-haul travel.
Full recovery
Return to full activity, exercise, and work. Final results may still be settling. Final follow-up with local doctor recommended.
Day 0: procedure completed under topical anaesthesia; bandage contact lens placed; sunglasses required outdoors. Vision is blurred and patients should not drive home.
Days 1-4: peak discomfort, especially day 2-3. Foreign-body sensation, photophobia, and tearing are common. Prescribed analgesia and lubricating drops are essential. Vision improves slowly and is typically usable but blurred during this period.
Day 4-7: epithelium regenerates; the bandage contact lens is removed at the day-4 or day-5 follow-up. Vision begins improving more rapidly thereafter.
Weeks 2-4: vision continues to refine. Some patients experience halos and starbursts at night, which usually settle.
Month 1-3: final refractive stabilisation. Most patients achieve 20/20 or 20/25 visual acuity by month 3. Mild dry eye is common during this period and is managed with lubricating drops.
Month 3-12: continued slow refinement. Enhancement (a second laser procedure for residual refractive error) is generally available between months 3 and 12 if needed.
PRK is a less common medical-tourism procedure than LASIK because of the slower visual recovery and the requirement to wear a bandage contact lens for 3-5 days. International patients should plan for 5-7 days in country to cover the procedure and the day-5 bandage-lens-removal review. Flying after PRK is generally permitted once the epithelium has healed and the bandage lens has been removed; some surgeons restrict swimming and dusty environments for several weeks.
A notable advantage for medical tourists is that PRK does not produce a permanent corneal flap, meaning there is no lifelong risk of flap dislocation from impact. Patients in contact sports or with occupations involving high G-forces or potential eye trauma should specifically discuss PRK with their surgeon.

There is typically meaningful discomfort during days 1-3 — described as a foreign-body sensation, similar to having sand in the eye. Prescribed analgesia and frequent lubricating drops help substantially. By day 4-5 most patients are comfortable. The procedure itself is painless under topical anaesthesia.
PRK produces equivalent final visual outcomes to LASIK in most studies (Cochrane Database, 2017) but takes longer to achieve them. The main advantage of PRK is biomechanical: no corneal flap is created, so there is no risk of flap dislocation later in life. The main disadvantages are slower recovery and more discomfort in the first few days. Modern femtosecond LASIK has narrowed the safety gap considerably.
Sometimes. Patients with thin corneas, borderline topography, large pupils, occupational requirements that exclude flaps, or high-impact-sport involvement may be PRK candidates when LASIK is contraindicated. A corneal topography and pachymetry assessment will identify whether your corneas can safely accommodate the procedure.
Most surgeons advise no driving for 5-7 days post-PRK until vision has substantially recovered and any double vision or significant blur has resolved. Some patients can drive earlier; the test is whether you can read a number plate from 20 metres with the operated eye.
PRK is not reversible in the sense of restoring the cornea to its original shape, but the lack of a permanent flap means the cornea retains better biomechanical integrity than after LASIK. If a refractive surprise occurs, an enhancement procedure can address it.
PRK is typically priced 10-20% below LASIK at the same clinic because the equipment cost is lower (no femtosecond flap creation). Total cost per eye varies by country and clinic.
Yes — PRK is FDA-approved for the correction of myopia, hyperopia, and astigmatism. The excimer laser ablation pattern can be calculated to address all three refractive errors in the same procedure, provided pre-operative pachymetry confirms adequate corneal thickness for the planned correction.
Final refraction typically stabilises at 1-3 months post-op. A small proportion of patients experience long-term regression toward myopia, particularly in higher corrections. Enhancement procedures are available between 3-12 months post-op if a refractive surprise persists.
