At Blue Fin Vision® Eye Clinic on Harley Street, London, we understand that choosing the right laser eye surgery procedure can be a daunting task. Two of the most popular options are PRK (Photorefractive Keratectomy) and LASIK (Laser-Assisted In Situ Keratomileusis). In this guide, we’ll explore the key differences between these two laser eye surgery techniques to help you make an informed decision.
Understanding Laser Eye Surgery
Before delving into the specifics of PRK and LASIK, it’s essential to understand that both are forms of laser eye surgery designed to correct refractive errors such as myopia (short-sightedness), hyperopia (long-sightedness), and astigmatism. The goal of these procedures is to reshape the cornea, allowing light to focus properly on the retina and improve vision.
PRK: The Pioneer of Laser Eye Surgery
PRK was the first type of laser eye surgery developed and has been in use since the 1980s. Here’s what you need to know about PRK:
The PRK Procedure
- Surface Preparation: The outer layer of the cornea (epithelium) is removed.
- Laser Application: An excimer laser is used to reshape the underlying corneal tissue.
- Healing: The epithelium regrows naturally over the treated area.
Advantages of PRK
- Suitable for Thin Corneas: PRK can be a better option for patients with thinner corneas.
- No Flap Complications: Since no flap is created, there’s no risk of flap-related issues.
- Potentially Safer for Active Lifestyles: Ideal for those involved in contact sports or high-impact activities.
Recovery and Results
- Longer Initial Recovery: It may take a few days to a week for vision to stabilise.
- Gradual Improvement: Full visual acuity is typically achieved within 1-3 months.
- Effective Outcomes: PRK has shown excellent long-term results for vision correction.
LASIK: The Popular Choice
LASIK has become the most widely performed laser eye surgery since its introduction in the 1990s. Here’s what sets LASIK apart:
The LASIK Procedure
- Flap Creation: A thin flap is created in the cornea using a femtosecond laser.
- Corneal Reshaping: The flap is lifted, and an excimer laser reshapes the underlying corneal tissue.
- Flap Replacement: The flap is repositioned, acting as a natural bandage.
Advantages of LASIK
- Rapid Visual Recovery: Most patients experience improved vision within 24 hours.
- Minimal Discomfort: Generally, less post-operative discomfort compared to PRK.
- Quick Procedure: The entire process typically takes about 15 minutes per eye.
Recovery and Results
- Fast Initial Recovery: Many patients return to work within a day or two.
- Immediate Vision Improvement: Significant vision enhancement is often noticed immediately after surgery.
- Stable Results: Vision typically stabilises within a few weeks.
Comparing PRK and LASIK
While both PRK and LASIK are effective in correcting vision, there are some key differences to consider:
- Corneal Tissue Preservation
- PRK: Removes less corneal tissue, making it suitable for patients with thinner corneas.
- LASIK: Requires more corneal tissue due to flap creation, but still highly effective for suitable candidates.
- Recovery Time
- PRK: Longer initial recovery period, with vision stabilising over several weeks.
- LASIK: Faster initial recovery, with many patients experiencing improved vision within 24 hours.
- Post-Operative Discomfort
- PRK: May involve more discomfort in the first few days after surgery.
- LASIK: Generally, less post-operative discomfort and faster return to normal activities.
- Risk Profile
- PRK: No risk of flap complications, potentially safer for certain lifestyles.
- LASIK: Slight risk of flap-related issues, but overall very safe with modern techniques.
- Long-Term Outcomes
Both PRK and LASIK have shown excellent long-term results for vision correction, with high patient satisfaction rates.
