Understanding the Different Types of Laser Eye Surgery

Explore the various types of laser eye surgery, including LASIK, LASEK, SmartSight, and Presbymax. Learn about their differences, benefits, and suitability for correcting vision problems.

Laser eye surgery is a popular vision correction method that can treat various refractive errors. This comprehensive guide explores the main types of laser eye surgery, their differences, and what to expect from each procedure.

 

LASIK (Laser-Assisted In-situ Keratomileusis)

LASIK is the most common type of laser eye surgery, known for its quick recovery and minimal discomfort. Key features:

  • Creates a thin flap in the cornea
  • Reshapes the underlying corneal tissue
  • Treats myopia, hyperopia, and astigmatism
  • Rapid visual recovery (often within 24 hours)
  • Suitable for about 90% of patients

Procedure steps:

  1. Numbing eye drops applied
  2. A thin corneal flap is created using a femtosecond laser
  3. Excimer laser reshapes the cornea
  4. Flap repositioned

LASEK (Laser-Assisted Subepithelial Keratectomy)

LASEK /TransPRK is an alternative to LASIK, often recommended for patients with thinner corneas. Key features:

  • No corneal flap created
  • The surface layer of the cornea (epithelium) is removed
  • Slower recovery compared to LASIK
  • Suitable for patients with thin corneas

Procedure steps:

  1. Epithelium removed manually or with the laser
  2. Excimer laser reshapes the cornea
  3. Bandage contact lens applied to aid healing

PresbyMAX

PresbyMAX is a specialised procedure for treating presbyopia (age-related reading vision problems). Key features:

  • Extends depth of focus in the non-dominant eye
  • Can correct myopia, hyperopia, and astigmatism simultaneously
  • Available only on specific laser platforms

Laser Blended Vision

This procedure addresses presbyopia by creating a "blended" vision between both eyes. Key features:

  • Dominant eye corrected for distance vision
  • Non-dominant eye corrected for near vision
  • Reversible procedure
  • Can be performed using LASIK or LASEK techniques

SmartSight™

SmartSight™ is the latest innovation in laser eye surgery, combining the benefits of SMILE with advanced safety features. Key features:

  • Uses lenticule extraction like SMILE
  • No corneal flap created
  • Smaller incision compared to LASIK
  • Includes advanced pupil tracking and astigmatism software
  • Currently available only at select clinics

Choosing the Right Procedure

The most suitable laser eye surgery procedure depends on various factors, including:

  • Your specific refractive error
  • Corneal thickness
  • Age
  • Lifestyle requirements

A comprehensive eye examination and consultation with our experienced consultants are essential to determine the best option for your individual needs.

Conclusion

Laser eye surgery offers various options to correct vision problems, each with its advantages. Understanding these different types can help you make an informed decision about your vision correction journey. Always consult with a qualified eye surgeon to determine the most appropriate procedure for your unique situation.
