Most patients who wish to see without glasses or contact lenses can be treated with laser eye surgery. However, there is a subset of patients who are not suitable for this procedure, and require an alternative treatment. This may be because of a high refractive error (typically -8.00D and worse for myopia and +4.00D and worse for hyperopia), thin corneas or corneas at risk of ectasia (corneal warpage). These patients may benefit from ICL surgery.
ICL (Implantable Collamer Lens) surgery is the placement of a thin, biocompatible gel material into the eye. It is carefully positioned in front of the human lens. It is like placing a contact lens in the eye to permanently improve vision. Since it is in the eye, it does not require cleaning or maintenance. This procedure has revolutionised the treatment of high refractive errors, as the ICL is specially made to measure for your eye. ICLs do not cause discomfort and are not visible in the eye. Because ICL surgery does not alter the structure of the eye, results have been shown to be predictable and stable.
