Frequently Asked Questions
Why would I choose PRK over LASIK?
PRK is preferred if you have thin corneas (<500 micrometers), participate in contact sports or military service, are concerned about flap complications, or have dry eye tendency. Long-term visual outcomes are equivalent to LASIK, with better corneal biomechanical stability.
How painful is PRK recovery?
Days 1-3 involve significant discomfort including foreign body sensation, light sensitivity, and tearing. About 90% of patients experience no severe pain; 10% have mild-to-moderate discomfort for 24-36 hours. Good pain management with prescription drops and oral medications makes it tolerable.
How long until I can see clearly after PRK?
Basic functional vision returns in 4-7 days (typically 20/30-20/50). Vision continues improving over 1-3 months, with final stabilization at 3-6 months. Most patients achieve driving vision within 1-4 weeks.
Can I have PRK if I'm in the military or aviation?
Yes, PRK is often specifically approved or required for military and aviation personnel because there's no flap that could dislodge under G-forces or trauma.
What is corneal haze and how is it prevented?
Haze is scarring of the cornea during healing. With modern mitomycin-C application (standard of care), significant haze is now rare (<1%). Mild temporary haze may occur and resolves with steroid drops.
Will I need reading glasses after PRK?
If you're over 40, you'll likely need reading glasses regardless due to presbyopia. PRK corrects distance vision. Monovision PRK is an option where one eye is corrected for near vision.
Can PRK be enhanced later if needed?
Yes, enhancement is possible after 3-6 months of stability if there's sufficient corneal tissue remaining. Either PRK or LASIK can be used for touch-ups.
Is PRK safer than LASIK?
PRK eliminates all flap-related risks and preserves better corneal biomechanics. Risk of ectasia is very low (0.03%). Final visual outcomes are equivalent. Some surgeons consider it safer for certain patient profiles.
What is TransPRK?
TransPRK is an all-laser version where the excimer laser removes both the epithelium and performs the correction in one step (no-touch technique). Studies show faster healing, less pain, and equivalent outcomes to standard PRK.
How does PRK compare to SMILE?
Both are flapless procedures with good corneal stability. SMILE has faster recovery (1-2 days vs 5-7 days) and less discomfort, but PRK can treat a wider range of prescriptions including hyperopia. Both preserve corneal strength better than LASIK.
Important: This information is for educational purposes only and does not constitute medical advice. PRK candidacy depends on individual eye characteristics, corneal thickness, prescription stability, and overall health. You must consult with a qualified ophthalmologist who can examine your eyes and review your complete medical history before making any decisions about vision correction surgery. Individual results vary, and not everyone is a suitable candidate for PRK. Actual costs vary by hospital, technology used, and individual treatment requirements—contact hospitals directly for current pricing.
PRK (Photorefractive Keratectomy) is the original laser vision correction procedure, FDA-approved since 1996. Unlike LASIK, which creates a corneal flap, PRK involves removing the outer layer of the cornea (epithelium) and reshaping the underlying tissue directly with an excimer laser. The epithelium then naturally regenerates over 3-5 days. This surface ablation approach eliminates flap-related complications and preserves more corneal tissue.
While PRK requires a longer recovery period than LASIK (5-14 days versus 1-3 days), it offers distinct advantages for suitable candidates: no flap means no flap complications, better corneal biomechanical stability, and lower risk of ectasia. PRK is often the preferred choice for patients with thin corneas (under 500 micrometers), those in contact sports or military professions where flap dislodgement is a concern, and anyone seeking maximum tissue preservation. Modern PRK with mitomycin-C application and advanced excimer lasers achieves visual outcomes equivalent to LASIK, with clinical studies showing 85-95% of patients achieving 20/20 vision or better for low-to-moderate myopia.
Thailand’s leading eye centers offer PRK using advanced excimer laser platforms—WaveLight EX500, VISX STAR S4, SCHWIND AMARIS, and ZEISS VISUMAX 800—with wavefront-guided and topography-guided treatment options. JCI-accredited hospitals with internationally trained surgeons provide comprehensive care packages at 55-65% lower cost than US pricing. The extended recovery period makes Thailand particularly suitable for PRK, as patients can recover comfortably with multiple follow-up appointments included before returning home.
International Patient Considerations
PRK requires a longer stay in Thailand than LASIK—plan for 10-14 days minimum:
- Pre-travel planning: Identify a local ophthalmologist in your home country who can provide post-operative care or emergency treatment if needed after you return
- Accommodation: Choose comfortable lodging near your clinic with blackout curtains—light sensitivity during days 1-3 makes a darkened room essential
- Medical records: Request complete surgical records, laser settings, and post-operative instructions to share with your home eye care provider
- Medications: Obtain sufficient supplies of steroid drops (4-6 weeks), antibiotic drops, and artificial tears for continued use at home
- Follow-up protocol: Initial healing checks occur before you leave Thailand; additional follow-ups at 1, 3, and 6 months can often be coordinated with your local ophthalmologist using your surgical records
- Flying considerations: Wait until epithelium is fully healed (5-7 days minimum) and you have surgical clearance; use lubricating drops frequently during flight due to dry cabin air
- Emergency contacts: Obtain 24/7 contact information for urgent post-operative concerns
Some complications require prompt attention and may need care from a local provider after you return home. Discuss international care coordination with your surgical team before your procedure.
