1. What is laser eye surgery?

Laser eye surgery is a simple procedure that takes anything from a matter of seconds to just a few minutes.

A cool beam advanced laser makes subtle adjustments to the shape of the surface of your eye (the cornea), correcting its tiny imperfections and making your vision clearer and sharper.

2. Am I suitable?

In Ireland, you are eligible to attend a laser eye surgery consultation from the age of 18. A Specialist Refractive Optometrist will determine your suitability for surgery at your consultation, depending on the health of your eyes, your prescription and some other factors.


3. Are there different types of laser eye surgery?

The two best-known and most popular types of laser eye surgery are LASIK and LASEK (also referred to as PRK). Both types can be enhanced by iDesign, a highly advanced innovation which takes over 1,200 measurements from your eye to create a personalised ‘map'. This allows your treatment to be tailored specifically to you to achieve the best results.
