Unlike corrective laser eye surgery, the ICL procedure is not limited to candidates who are low myopes or hyperopes. With ICL, the extent of refractive error is not a barrier as the ICL can be customised to suit each individual.
Those between the ages of 21-45 years old, with near-sighted or far-sighted vision and / or astigmatism are suitable candidates. It is preferable that candidates have no pre-existing eye conditions such as glaucoma, diabetes and inflammatory eye conditions such as uveitis. Women who are pregnant or nursing should wait to have the ICL implanted. Lastly, those narrow anterior chamber depths or poor endothelial cell density may not be a good ICL candidates.
