Implantable Collamer Lens (ICL) surgery is a vision correction procedure that improves eyesight by inserting a specially prescribed collamer lens inside the eye. It corrects refractive errors without shaving or removing corneal tissue, and the lens is placed behind the iris while preserving the eye’s structure.

EVO ICL is used to correct near-sightedness (myopia) and astigmatism by placing a prescribed lens inside the eye behind the iris, without cutting or removing corneal tissue.

ICL corrects vision by inserting a lens inside the eye, rather than reshaping the cornea with a laser. It’s described as having fast recovery, reduced glare and dry eye, reduced myopia progression, and the possibility to return to the original condition; however, if the lens size is not right, re-surgery may be necessary.

Yes. Because ICL does not change the shape of the cornea, the implanted lens can be removed or changed in the future if needed.

The procedure is performed in three steps: (1) mydriatic eye drops are administered to dilate the pupil, (2) a small incision of about 3mm is made in the cornea and the lens is inserted, and (3) the lens is precisely positioned and secured between the iris and the natural lens. Lens implantation is completed in under 2 minutes.

The incision is a minimum of 3mm, and the overall treatment duration takes 3–5 hours. The recovery period is just 1 day, with caution advised for one week.

ICL surgery is recommended for people who need revision surgery due to myopia regression after LASIK/LASEK, those with very severe myopia or astigmatism, those with thin corneas, severe dry eye, a wound or disease on the cornea, or low endothelial cells.

Yes, ICL can treat astigmatism, but alignment is critical. If the astigmatic axis is inserted with even slight misalignment, vision may not be accurately corrected and this can cause dizziness and residual astigmatism. Astigmatism correction is supported by navigation-based technology that tracks the eye in real time and provides guidelines to minimize errors, including use of the IOLMaster 700 laser ophthalmometer with the Forum Network, a high-performance surgical microscope, and the LUMERA 700 image transmission device.

There are two main types: posterior chamber lenses and anterior chamber lenses. Posterior chamber lens implantation is the standard method for most patients, placing the lens behind the iris and in front of the natural (crystalline) lens. In cases where posterior implantation is not possible due to the eye’s natural shape or complications (including illness, physical trauma, or prior surgeries), anterior chamber implantation is an alternative, with the lens inserted directly into the cornea.

EVO+ ICL is a posterior lens made of patented collamer material with a 360μm hole at the center to help prevent blockages and facilitate flow within the eye. TORIC EVO+ ICL provides UV protection, reduced glare due to a wide optical area, and a low risk of dry eye, and it can correct myopia from -0.50 to -18D and astigmatism from -1D to -6D with a single surgery.

Choosing the correct lens size and prescription is important for both comfort and safety. If the lens size is too large, it may shift forward, narrow the gap to the endothelium, increase friction with the iris, block the aqueous humor drainage duct, and raise intraocular pressure—this can cause pain and may require measures to lower intraocular pressure. If the lens size is too small, it may rub against the eye’s lens and increase the risk of cataracts. If the prescription is not correct, double vision and dizziness may occur.

A standard approach requires at least 4 visits over approximately one week (exam and lens ordering, primary monocular surgery, secondary monocular surgery, and post-operative follow-up). Our streamlined approach allows same-day bilateral surgery after examination and treatment, with a post-operative follow-up, for a minimum of 2 visits over 2 days.
