Implantable Lenses (ICL)

Implantable Contact Lens (ICL) surgery is a corrective soft lens that is placed within the eye to correct myopia. The lens is implanted in front of the natural lens of the eye, via a small cornea incision, and bends light rays into the retina to form a clear image.

This procedure, although similar to LASIK by correcting refractive errors, does not require the need to remove corneal tissue. It also has the potential to provide very high-quality vision after surgery.

Who should consider ICL Surgery?

In general, implants can treat much higher degrees of myopia of up to -19D (1,900 degrees) per eye, while Lasik is usually limited to a maximum of -12D to -14D (1,200 to 1,400 degrees). Hence, implants are especially suitable for those with high myopia but also be used to correct lower degrees if the patient is suitable. ICL surgery is a very good alternative for patients who are not good candidates for LASIK or PRK due to thin or abnormal corneas or who have a pre-existing dry eye.


One benefit of implants is that it is reversible, and can be removed or replaced when the refractive error changes.

Another positive to the procedure is that it is quick. An average surgery takes 10 to 20 minutes, and recovery generally happens overnight

ICL are unnoticeable to both the patient and observers.


While safe, the procedure carries with it small risks. The level of risk is similar to LASIK but the type of risk is different. For example, there is a risk of infection, just like LASIK. But unlike the latter, the infection may occur on the inside of the eye as opposed to the outside in LASIK.
