From PRK to Contoura Lasik to Touchless Streamlight TransPRK: The Evolution of LASIK Eye Surgery

lasik eye surgery

Imagine a world where the morning blur vanishes not with a rub of the eyes but with the marvel of modern medicine. Welcome to the transformative journey of Lasik eye surgery, a tale of three revolutionary generations that have redefined clarity.  

Join us as we delve deeper into the evolution of laser eye surgery, exploring how each generation has built upon the last to offer a clearer future for millions around the globe. 

Visionary Beginnings: The Evolution of LASIK Eye Surgery

Our journey begins in the late 20th century with the first generation of LASIK—PRK. This groundbreaking procedure laid the foundation for what was to come, offering new hope for those dependent on glasses and contacts. 

As we moved into the new millennium, the second generation emerged with the advent of traditional LASIK, a technique that refined the process by creating a corneal flap, allowing for faster healing and better vision correction. This method quickly became the gold standard for refractive eye surgery. We now have contoura Lasik, the Gold standard in Lasik eye surgery.

Today, we stand at the forefront of the third generation with the introduction of Streamlight TransPRK surgery. This minimally invasive, Touchless, Flapless and Bladeless procedure represents the pinnacle of precision and recovery, providing patients with a comfortable experience and outstanding outcomes. 

We’ll investigate why certain procedures may be more suitable in various scenarios and examine their comparative advantages. 

1st Generation: PRK (Photorefractive Keratectomy)

PRK is a refractive eye surgery designed to correct vision issues such as farsightedness, astigmatism, and nearsightedness. Unlike LASIK, PRK involves the removal of the cornea’s outer layer (the epithelium) before using an excimer laser to reshape the cornea’s deeper layers.  

This procedure helps to correct the curvature of the eye, improving the eye’s ability to focus light and thus enhancing vision.  


  • High success rate: PRK is known for its effectiveness and high rate of patient satisfaction. 
  • No corneal flap: Unlike LASIK, PRK doesn’t involve creating a corneal flap, which eliminates the risk of flap complications. 
  • Suitable for thin corneas: PRK can be a better option for patients with thinner corneas who may not be candidates for LASIK.


  • Longer recovery time: The healing process for PRK is typically longer than that for LASIK, with initial recovery taking from several days to a month. 
  • Post-surgery discomfort: Patients may experience more discomfort and pain during the recovery period compared to LASIK. 
  • Risk of corneal haze: There’s an increased risk of corneal haze, which can affect vision clarity after PRK. 

These points can help you understand what to expect from PRK and make an informed decision about your eye surgery options. 

2nd Generation: LASIK


  • High success rate: Most patients achieve 20/20 vision or better. 
  • Quick recovery: Many experience significant vision improvement within 24 hours. 
  • Minimal pain: The procedure is generally pain-free, with minor discomfort. 


  • Potential side effects: Dry eyes, glare, halos, and other visual disturbances may occur. 
  • Not reversible: Changes made to the cornea cannot be undone. 
  • Not suitable for everyone: Those with certain eye conditions or unstable vision may not be candidates. 


Complications related to the corneal flap are uncommon, and by choosing Suruchi Hospital Eye, which boasts experienced surgeons, your likelihood of facing such complications is significantly reduced.

3rd Generation: Streamlight TransPRK

Alcon Streamlight is a minimally invasive laser eye surgery that corrects myopia and astigmatism. It is a touchless, one-step laser treatment that reshapes the cornea and improves vision.


  • Minimally invasive: No flap is created, reducing the risk of flap-related complications. 
  •  Safest: Best for patient safety.
  • Fewer dry eye symptoms: Less disruption of corneal nerves may lead to fewer dry eye issues post-surgery. 
  • High precision: Utilizes advanced Alcon Streamlight technology for precise correction. 
  •  More treatment range


  • Recovery: The Patient feels better than PRK, but recovery is little slower than Contoura Lasik.


However, it’s important to consult with an eye care professional to determine what the right choice is for your specific needs.
