LASIK vs PRK: Understanding Your Laser Vision Correction Options

Laser vision correction is one of the most effective ways to reduce dependence on glasses or contact lenses. At Clearsight, we offer advanced treatment options tailored to each patient’s eyes, including LASIK and TransPRK. 

Understanding the differences between these procedures is essential in choosing the right approach for your vision. 

What Is LASIK? 

LASIK (Laser In Situ Keratomileusis) is the most well-known form of laser eye surgery and is widely recognised for its fast recovery and excellent visual outcomes. 

This procedure uses two highly advanced lasers in a precise, computer-guided process. 

How LASIK Works 

  • A femtosecond laser (IntraLase) creates a thin, customised flap in the cornea  
  • The flap is gently lifted  
  • An excimer laser reshapes the underlying corneal tissue to correct vision  
  • The flap is repositioned, where it naturally adheres without stitches  

This process allows for highly accurate correction of myopia (short-sightedness), hyperopia (long-sightedness), and astigmatism. 

Key Benefits of LASIK 

  • Rapid visual recovery (often within 24 hours)  
  • Minimal discomfort  
  • High precision using 3D corneal mapping technology  
  • Proven long-term results 
What Is TransPRK? 

TransPRK (Transepithelial Photorefractive Keratectomy) is a flap-free laser vision correction procedure and an excellent option for patients who may not be suitable for LASIK. 

Unlike LASIK, TransPRK is performed entirely by the excimer laser in a single, seamless step. 

How TransPRK Works 

  • The excimer laser gently removes the outer layer of the cornea (epithelium)  
  • The same laser reshapes the cornea to correct your prescription  
  • No surgical instruments touch the eye during the procedure  

At Clearsight, we use SmartSurfACE technology, which incorporates advanced 3D modelling to optimise laser precision and create a smoother corneal surface—supporting improved healing. 

After the procedure, a bandage contact lens is placed on the eye to aid comfort and healing, typically removed after five days. 

LASIK vs PRK: What’s the Difference? 

While both procedures achieve the same goal—clear, unaided vision—they differ in technique and recovery.

Which Procedure Is Right for You? 

The choice between LASIK and TransPRK depends on several factors, including: 

  • Corneal thickness and shape  
  • Lifestyle and activity level  
  • Prescription strength  
  • Eye health, including dry eye or other conditions  

A comprehensive assessment is essential to determine the safest and most effective option for your individual needs. 

Why Personalised Assessment Matters 

Laser vision correction is not a one-size-fits-all procedure. At George St Eye Centre, we use advanced diagnostic technology to assess your eyes in detail and recommend the most appropriate treatment. 

Our goal is to achieve the best possible visual outcome while maintaining long-term eye health. 

Final Thoughts 

Both LASIK and TransPRK are safe, effective, and highly advanced procedures that can significantly improve your quality of life. 

The key to success lies in selecting the right procedure for your eyes. With expert guidance and personalised care, laser vision correction can deliver clear, reliable vision with long-lasting results.
