- PRK costs $900–$1,300 for both eyes in Colombia vs $4,000–$6,000 in the United States
- Long-term visual results are identical to LASIK — the only difference is recovery time
- Ideal for patients with thin corneas, active lifestyles, or military/first responder careers
- Recovery takes 1–2 weeks (vs 24–48 hours for LASIK) — plan accordingly for your trip
- Modern TransPRK (single-pass, no-touch) has significantly improved the recovery experience
Why PRK Still Matters in 2026
PRK (Photorefractive Keratectomy) doesn't get the same marketing attention as LASIK or SMILE, but it remains an essential vision correction procedure — and for certain patients, it's the best option available.
PRK was the original laser vision correction procedure, predating LASIK by several years. Instead of creating a corneal flap (like LASIK) or extracting a lenticule (like SMILE), PRK removes the thin surface layer of the cornea (the epithelium) and then reshapes the underlying tissue with the same excimer laser used in LASIK. The epithelium regenerates naturally over 3–5 days.
The critical advantage: because PRK doesn't create a flap, it preserves more corneal tissue and biomechanical strength. This makes it the procedure of choice for patients who don't qualify for LASIK due to thin corneas, and for anyone who needs maximum corneal integrity.

|---|---|---|
| PRK surgery (both eyes) | $4,000–$6,000 | $900–$1,300 |
| Wavefront-guided PRK | $5,000–$7,000 | $1,200–$1,600 |
| Pre-op exam & diagnostics | $200–$500 (often separate) | Included |
| Post-op medications | $100–$300 | Included |
| Follow-up visits | $150–$300/visit | Included |
| Bandage contact lenses | $50–$100 | Included |
| Estimated total with travel | $4,000–$6,000 | $1,800–$2,800 |
Who Should Choose PRK Over LASIK?
PRK is often positioned as a “second choice” to LASIK, but there are patients for whom it's the first choice:
Thin corneas (under 500 microns): LASIK requires sufficient corneal thickness to safely create a flap and still leave enough residual tissue (250+ microns). If your corneas are too thin for LASIK, PRK can often still be performed safely because no tissue is used for a flap.
Contact sport athletes: Boxers, MMA fighters, basketball players, and anyone who might take a hit to the face. While LASIK flap dislocation after healing is rare, PRK eliminates the risk entirely because there's no flap to displace.
Military and first responders: The US military has historically preferred PRK for active-duty service members. No flap means no vulnerability in combat or high-impact situations. Many military branches specifically approve PRK for pilots and special operations.
Patients with corneal irregularities: Certain corneal surface conditions (epithelial basement membrane dystrophy, for example) are better treated with PRK's surface approach than LASIK's flap.
Patients who want maximum corneal strength: If long-term corneal biomechanical integrity is a priority — whether for peace of mind or because your corneas are on the thinner side of normal — PRK preserves more structural strength than LASIK.
PRK Recovery: What to Expect
PRK's longer recovery is its main trade-off compared to LASIK. Here's what a realistic timeline looks like:
Day 0 (surgery day): The procedure takes about 10–15 minutes per eye. A bandage contact lens is placed on each eye. You'll have blurry vision and mild stinging as the numbing drops wear off. Prescription pain drops and oral pain medication manage discomfort.
Days 1–3: This is the most uncomfortable period. The epithelium is regenerating, and your eyes may be light-sensitive, watery, and uncomfortable (though not typically painful with modern medications). Vision is blurry. Stay indoors, rest your eyes, and use your drops on schedule.
Days 4–5: The bandage contact lens is typically removed once the epithelium has healed. Vision begins to clear noticeably, though it will still be slightly hazy.
Week 1–2: Vision continues improving. Most patients can drive and work with a computer, though eyes may tire more easily. Steroid drops continue (taper over weeks to months).
Weeks 3–4: Most patients have functional vision for daily activities. Fine tuning continues.
Months 1–3: Vision stabilizes to its final outcome. The final result is identical to what LASIK would have achieved — the same excimer laser does the same reshaping. Only the healing path differs.
Because PRK recovery takes longer than LASIK, plan for a 10–14 day stay in Colombia rather than the 7–10 days typical for LASIK. The extra days are for the epithelium to heal enough for comfortable travel. Even at 14 days, your total trip cost in Colombia will be less than the US procedure alone.
Modern PRK: TransPRK and Surface Ablation Advances
If your mental image of PRK involves a surgeon scraping cells off your cornea, update that picture. Modern PRK techniques have significantly improved the procedure:
TransPRK (no-touch PRK) uses the excimer laser to remove the epithelium and reshape the cornea in a single, continuous pass. There's no manual scraping — the laser does everything. This is faster, more precise, and results in less discomfort and faster healing than traditional PRK.
Mitomycin C (MMC) application is now standard in PRK to prevent corneal haze, which was historically a concern, especially for higher prescriptions. A brief application during surgery dramatically reduces haze risk to near-zero for most patients.
Cooling and cross-linking adjuncts are being used at some advanced clinics to further optimize healing. These incremental advances make PRK in 2026 a meaningfully better experience than PRK even five years ago.
PRK vs LASIK: Long-Term Results
Here's the most important thing to know: long-term visual outcomes of PRK and LASIK are statistically identical. Multiple studies with 5, 10, and 15-year follow-up data show equivalent visual acuity, stability, and patient satisfaction. The difference is entirely in the recovery experience.
One area where PRK may have a slight long-term edge: corneal ectasia (progressive corneal weakening) is even rarer after PRK than after LASIK, because PRK preserves more corneal biomechanical strength. For patients with borderline corneal thickness or other risk factors, this provides an additional safety margin.
