Just when you thought you knew all your laser eye surgery options, there’s another one to consider—PhotoRefractive Keratectomy (PRK). This form of laser surgery offers a similar result to its cousin, LASIK, albeit through a different approach. While LASIK may offer a quicker recovery initially, PRK might provide more long-term safety benefits for those who undergo it. This post will examine what PRK vs LASIK, what the former entails, and whether it’s a suitable option for you.

PRK Procedure

The PRK procedure begins with anesthetic drops to numb the eye. The surgeon then removes the outer layer of the cornea, known as the epithelium. Following this, an excimer laser is used to reshape the cornea, correcting vision issues such as nearsightedness, farsightedness, and astigmatism. A bandage contact lens is placed over the eye to protect it during healing. The entire procedure typically takes about 15 minutes per eye, and unlike LASIK, no corneal flap is created during PRK.

Advantages of PRK Mechanism of Action for the Patient

PRK offers several significant advantages that make it an appealing choice for many patients: 

  • Since PRK does not involve creating a flap in the cornea, patients are not at risk for flap-related complications that can occur with LASIK. This makes PRK a safer option for individuals concerned about such risks.
  • Suitable for patients with thin corneas: Many individuals are disqualified from LASIK due to insufficient corneal thickness. PRK is an excellent alternative for these patients as it can effectively correct vision without compromising corneal integrity.
  • Less corneal tissue removal: During PRK, less corneal tissue is removed compared to LASIK. This preservation of corneal tissue can be particularly beneficial for long-term eye health and stability.
  • Reduced risk of dry eye syndrome: Patients who undergo PRK may experience less dry eye post-surgery compared to those who have LASIK. This is particularly important for individuals who already suffer from dry eye conditions.
  • Safer for active lifestyles: For athletes or individuals engaged in high-impact activities, PRK may be a better choice since no flap could be dislodged due to trauma or injury.
  • Ability to treat higher degrees of myopia: PRK can correct more severe vision impairments than LASIK, making it suitable for patients with higher degrees of myopia who may not qualify for LASIK.

PRK Statistics and Success Rate

The effectiveness of PRK is impressive and backed by numerous studies: 

  • About 95% of patients achieve 20/40 vision or better without corrective lenses after one year. This level of vision is typically sufficient for most daily activities, including driving.
  • Approximately 70% of patients attain 20/20 vision following the procedure, representing optimal visual acuity without glasses or contacts.
  • Overall, 92% of patients see improvements to 20/40 vision or better after undergoing PRK.
  • Patient satisfaction rates are remarkably high at around 95%, indicating that most individuals are pleased with their results and quality of life improvements post-surgery.
  • Importantly, results from PRK become comparable to those from LASIK after about six months, showcasing its effectiveness over time.

PRK vs LASIK

When comparing PRK vs LASIK, several key differences emerge that can influence your decision:

While both procedures are effective and share similar long-term outcomes and success rates, they differ significantly in recovery time and initial discomfort levels. Patients opting for PRK should be prepared for a more extended healing period but may benefit from its unique advantages based on their circumstances. 

When PRK is a Better Option than LASIK

  • PRK may be more suitable in various scenarios, such as patients with thin corneas who cannot safely undergo LASIK.
  • For individuals with irregular corneal surfaces, which might complicate flap creation.
  • Patients who already suffer from dry eye syndrome and are wanting to minimize further risk.
  • This is for athletes or individuals involved in high-impact activities where eye trauma is a concern.
  • This is for patients with higher degrees of myopia who require more extensive correction.
  • For those at increased risk of eye trauma (e.g., military personnel or first responders).
  • When there’s a need to preserve more corneal tissue due to existing eye conditions or future considerations.
