Photorefractive keratectomy (PRK) is one of the original types of laser eye surgery used to reshape the cornea and improve vision. For many patients, PRK offers an excellent alternative to LASIK—especially for those with thinner corneas or lifestyles that make flap-based procedures less ideal.
If you’re exploring vision correction in Houston, understanding how PRK works, what recovery involves, and how it compares to LASIK will help you make an informed decision.
What Is PRK Surgery?
PRK, or photorefractive keratectomy, corrects refractive errors such as nearsightedness, farsightedness, and astigmatism. During surgery, a laser gently reshapes the corneal surface so that light focuses properly on the retina.
Unlike LASIK, PRK doesn’t involve creating a corneal flap—the thin outer layer (epithelium) is removed and naturally regenerates during healing. This makes PRK ideal for patients with thinner corneas, irregular surfaces, or those in careers like military service, law enforcement, or contact sports where flap complications may occur.
At CLS Health, our board-certified ophthalmologists perform PRK using advanced laser technology to ensure safety and precision.
The PRK Procedure: Step-by-Step
- Comprehensive Eye Exam: Your ophthalmologist measures corneal thickness, pupil size, and checks for dry eye or other conditions.
- Numbing Drops: Applied to keep the eye comfortable throughout the procedure.
- Removing the Epithelium: The thin surface layer of the cornea is gently removed.
- Laser Reshaping: An excimer laser reshapes the cornea within minutes.
- Protective Bandage Lens: A soft lens is placed over the eye to protect it while the surface layer heals.
The procedure typically takes 10–15 minutes per eye, with patients returning home the same day.
PRK vs. LASIK: Which Is Better for You?
PRK and LASIK achieve the same visual outcomes—your ophthalmologist will help determine which procedure best fits your eye health and lifestyle.
Both procedures deliver excellent long-term results—your ophthalmologist will help you choose based on your eye health, corneal thickness, and lifestyle.
PRK Recovery: Timeline and Expectations
Healing takes longer than LASIK but delivers comparable results once complete.
- Days 1–3: Blurry vision and mild soreness or light sensitivity are common. Eye drops and medications help manage comfort. These early symptoms are temporary and a normal part of the healing process.
- Weeks 1–2: The surface layer heals, and the bandage contact lens is removed. Vision begins to clear.
- Months 1–3: Vision stabilizes gradually, often reaching driving-level clarity within several weeks.
- Months 3–6: Full recovery achieved, with sharper, clearer vision.
During recovery, avoid eye makeup for a week, swimming or hot tubs for two weeks, and always wear sunglasses outdoors. Your care team will schedule follow-up visits to monitor healing and adjust medications as needed.
PRK Surgery Cost
PRK surgery in Houston generally costs a few thousand dollars per eye—similar to LASIK. Exact pricing depends on your surgeon’s experience, clinic technology, and specific treatment plan.
While most insurance plans don’t cover elective vision correction, financing and payment plans are often available. In cases where PRK is medically necessary (e.g., intolerance to contacts), partial coverage may apply. Our team can help you review financing and payment options before scheduling your procedure.
How Long Does PRK Last?
PRK provides long-lasting results for most patients. Once healed, clear vision typically lasts for decades. However, age-related changes such as presbyopia (near vision loss) or cataracts can still affect vision later in life—conditions unrelated to the PRK procedure itself.

FAQs
Yes, enhancement procedures may be possible years later if vision shifts or the initial correction is incomplete.
PRK removes the surface layer rather than creating a flap, eliminating flap-related risks. Both are safe and effective when performed by experienced surgeons.
Patients with severe dry eye, uncontrolled diabetes, corneal disease, or unstable prescriptions may not qualify. Your ophthalmologist will determine suitability after a full evaluation.
