What is ICL Surgery?

ICL stands for Implantable Collamer Lens. It is a form of refractive vision correction which leaves the cornea completely intact and corrects any refractive error by means of an artificial lens which sits behind the iris and in front of the natural lens of the eye.

How does ICL surgery work?

During ICL surgery, a small wound about 3mm is created with a sharp blade. Through this wound, the ICL is inserted into the eye and the legs of the lens is then tucked behind the iris. This lens is customised to each individual, correcting any myopia (short-sightedness) and astigmatism.

What are the benefits of ICL surgery?

Benefits of ICL surgery include:

  • Freedom from glasses and contact lenses
  • No risk of flap related complications e.g. Flap dislocation, flap striae, epithelial ingrowth
  • Tissue saving as the cornea is completely left intact
  • May be more suitable in patients with thin corneas
  • May be more suitable in patients with high myopia
  • May have less dry eyes compared with other means of laser vision correction
  • ICL surgery is reversible
