Implantable Collamer Lens (ICL) surgery is a vision-correction procedure in which a thin, biocompatible lens is placed inside the eye, behind the iris and in front of the natural lens.
An implantable contact lens is an option for selected patients who require refractive correction and may not be suitable for corneal laser procedures. An implantable contact lens is placed inside the eye to provide refractive correction. It differs from an external contact lens and from corneal laser procedures.
Unlike LASIK, ICL does not remove corneal tissue and the natural lens remains intact.
ICL can be an excellent option for patients with:
A comprehensive eye examination, including corneal imaging and anterior-segment measurements, is essential to determine suitability.
Yes. ICL is considered a safe and well-established vision-correction procedure when performed in appropriately selected patients by an experienced surgeon.
Modern ICLs are designed to be biocompatible and can provide excellent visual outcomes.
As with any eye surgery, there are potential risks, including increased eye pressure, inflammation, infection, cataract formation, or the need for lens repositioning/replacement.
Careful patient selection and regular follow-up help minimize these risks.
In short: ICL offers high-quality vision correction without removing corneal tissue, making it an attractive option for many patients who are not ideal candidates for LASIK.

Micro-thin implant as an alternative or for those not suitable for laser vision correction:
ICL surgery is suitable for those who have –
“Additive” surgery – so can be reversed
Positioned behind the iris and in front of the natural lens
20+ year track record
Over 800,000 implanted worldwide
Useful in Keratoconus and dry eye where laser eye surgery is contraindicated
Suitability for ICL surgery is best determined at consultation where a thorough eye examination
backed up with specific tests and measurements of eye dimensions. Generally the procedure is
suitable for those with a stable prescription who are shortsighted from -0.50 to -20, farsightedness
from +0.50 to +10.00, with astigmatism from 0.50 to 6.00D in those aged between 21 and 60 years
old.
No. ICL is an implantable lens placed inside the eye, unlike an external contact lens.
