For patients who want freedom from glasses or contact lenses but are not ideal candidates for LASIK, Photorefractive Keratectomy (PRK) can be an excellent alternative. PRK corrects nearsightedness, farsightedness, and astigmatism using laser technology, much like LASIK, but with a different approach to preparing the cornea. This makes it especially suitable for individuals with thin corneas or certain corneal surface irregularities.
At Cornerstone Eye Associates, PRK is performed by Dr. Claire Y. Chu, a board-certified ophthalmologist recognized for her advanced surgical skill and dedication to patient-centered care. With over 15 years of teaching experience at UT Southwestern Medical School, publications in ophthalmic research, and recognition in D Magazine’s Best Doctors List, Dr. Chu provides patients with reliable, personalized solutions for lasting vision correction.
What Is PRK Surgery?
PRK was the first laser vision correction procedure approved in the United States and remains a safe, effective choice for many patients today. The treatment uses an excimer laser to reshape the cornea so light can focus properly on the retina. Unlike LASIK, which creates a corneal flap, PRK gently removes the outer layer of corneal cells before reshaping begins. This layer naturally regenerates during recovery.
Because PRK avoids the creation of a flap, it is often recommended for patients whose corneas are too thin for LASIK. The results are just as precise, and many people experience excellent long-term vision without glasses or contacts.
How to Prepare for Your PRK Treatment
Preparing for PRK is simple, and a few small steps can help make your experience more comfortable. Before surgery, Dr. Chu will evaluate your eyes and share specific instructions. These often include pausing contact lens use for a short period, avoiding eye makeup or lotions, and picking up any prescribed drops ahead of time.
To get ready for the day of your procedure, keep the following in mind:
- Wear comfortable clothing
- Skip all cosmetics or creams around the eyes
- Bring sunglasses for the ride home
- Arrange for someone to drive you
It also helps to set up a quiet, low‑light space at home where you can rest during the first few days of healing. Having artificial tears, a few simple meals, and non‑screen activities available can make early recovery easier. Dr. Chu and her team will review everything with you so you feel fully prepared.
How PRK Compares to LASIK
Both PRK and LASIK use advanced laser technology to reshape the cornea and correct vision, but the techniques differ slightly. LASIK involves creating a thin flap in the cornea before the laser treatment begins. In PRK, that flap is skipped—Dr. Chu gently removes the outermost layer of the cornea instead, allowing the laser to treat the surface directly.
Because PRK doesn’t require a flap, it’s often preferred for patients with thin or irregular corneas or those with lifestyles that make eye trauma a concern. While LASIK generally offers faster recovery, PRK provides equally strong long-term results. The choice between the two depends on your eye structure, visual goals, and personal preferences, which Dr. Chu will walk through with you during your consultation.
Is PRK Right for Your Lifestyle?
PRK can be an excellent option for people whose careers, hobbies, or routines involve physical activity, contact sports, or high-impact environments. Since there’s no corneal flap involved, there’s less risk of post-operative complications related to trauma, making PRK especially appealing to:
- Athletes and fitness enthusiasts
- Military personnel or first responders
- Patients in construction or other hands-on professions
- Anyone with a busy lifestyle who prefers a low-maintenance, long-term solution
If you’ve been told LASIK may not be the best fit, or you want vision correction with long-term stability, PRK could be a good fit for your goals. Dr. Chu will help you explore how PRK fits your day-to-day life and whether it’s the best match for your eyes and routine.
Who Is a Candidate for PRK?
PRK may be recommended for patients who want clearer vision but do not qualify for LASIK. Ideal candidates include:
- People with thin or irregular corneas that make flap-based surgery less safe
- Active individuals or athletes who may risk corneal injury with LASIK
- Patients with dry eyes who might not respond well to flap-based procedures
- Adults with stable prescriptions and healthy overall eye health
A thorough eye exam will help determine if PRK is the right choice. Dr. Chu may also simulate expected outcomes so patients can understand the benefits of choosing PRK over other refractive options.
