PRK is one of the most common laser eye surgery options next to LASIK, and the two procedures share many similarities. The right laser eye surgery for you depends on your unique needs, and for some people that means that PRK is ultimately the best fit. If you are unable to have LASIK surgery, you may be a candidate for PRK laser eye surgery. Ahead, we’ll discuss what goes into your PRK eye surgery candidacy, along with the factors that will help your laser eye surgery specialist determine which procedure is right for you.
PRK Eye Surgery Candidacy: What You Need to Know
Corneal Considerations
Corneal thickness is paramount in PRK suitability. If you have thinner corneas, and were told LASIK was not an option, PRK might be a viable alternative. Since PRK does not require the creation of a corneal flap, it preserves more corneal tissue, making it suitable for those with thinner corneal measurements. However, precise measurements are critical. We assess corneal thickness and identify any irregularities, such as keratoconus, which would disqualify a patient. Previous corneal surgeries or significant scarring can also affect corneal integrity, making detailed evaluations indispensable.
Age and Vision Stability
Candidates for PRK should be at least 18 years old, as ocular development stabilizes by this age. Additionally, a stable vision prescription for at least one year is recommended to ensure the longevity of the surgical results. While there’s no strict upper age limit for PRK, general health and healing capabilities are crucial factors.
Ocular Health
Prospective PRK patients must have healthy eyes, free from conditions such as:
- Keratoconus: A progressive thinning of the cornea.
- Glaucoma: Increased intraocular pressure causing optic nerve damage.
- Cataracts: Clouding of the eye’s natural lens.
- Severe Dry Eye Syndrome: Insufficient tear production leading to eye discomfort.
The presence of these conditions can complicate the healing process and affect surgical outcomes.
Lifestyle Factors
Lifestyle and occupational demands play a significant role in determining PRK suitability. We assess your daily activities and visual requirements to ensure that PRK aligns with your lifestyle. PRK is often recommended for individuals engaged in activities with a high risk of eye injury, such as contact sports or military service. The absence of a corneal flap eliminates the risk of flap-related complications in scenarios where eye trauma is possible.
Comprehensive Evaluation
At TLC Laser Eye Centers, we perform detailed assessments by a qualified doctor to determine suitability for PRK. This evaluation typically includes:
- Corneal Topography: Mapping the surface curvature of the cornea.
- Pachymetry: Measuring corneal thickness.
- Refraction Assessment: Determining the precise prescription.
These tests help in formulating a personalized surgical plan tailored to the individual’s ocular characteristics.

Post-Operative Care, Recovery, and Results
PRK typically has a longer recovery time than LASIK, as the epithelium (thin, outermost layer of the eye) takes about 5-7 days to regenerate fully. A protective contact lens is placed over the eye to aid in healing during this time. Patients may experience temporary discomfort, light sensitivity, and blurred vision during the healing process. However, the final visual outcomes of PRK and LASIK are similar, with most patients achieving 20/20 vision or better after recovery.
Post-operative care is critical for achieving optimal visual outcomes after PRK. We provide detailed instructions on medication use, eye protection, and follow-up appointments. You’ll be advised to use lubricating eye drops to minimize discomfort and promote healing. We monitor corneal healing and visual acuity during follow-up visits and address any potential complications promptly.
PRK remains a highly effective vision correction option, particularly for those who are not ideal candidates for LASIK. Its long-standing success in improving vision makes it a reliable choice for many seeking freedom from glasses or contact lenses. Take the next step toward clearer vision with TLC Laser Eye Centers!
