An ICL (Implantable Collamer Lens) is a so-called phakic lens, meaning that it is placed inside the eye in addition to the own lens. It is inserted into the posterior chamber, between the iris and the lens (in the ciliary sulcus). There is another version of a phakic lens which is placed into the anterior chamber and fixed to the iris.
The Visian ICL is made of a very flexible material biocompatible with the eye tissue. Implantation inside the eye is therefore easily done since it readily folds to be inserted via micro incisions of the cornea It is placed in the posterior chamber of the eye, right behind the iris, but without touching it. People looking at you will not perceive the lens. To them it will seem as if you had no additional lens inside your eyes. An ICL can correct myopia, hyperopia and astigmatism.
The candidate for an ICL should be between 21 and 45 years old and should have myopia, hyperopia and / or astigmatism. Ideally no prior ocular surgery has been performed. The patient should not suffer from any other eye diseases like glaucoma, diabetic retinopathy, uveitis etc.
In order to determine whether you are an appropriate candidate for this procedure we will perform specific examinations. Using latest technology, we will measure the depth of the chamber and check the overall health condition of the structures of the eyes. Discover the requirements for being a candidate.
ICL surgery is an out-patient procedure of short duration. Topical (local) anesthesia is used for this procedure, so you will be awake throughout the intervention. The pupil has to be well dilated for which eye-drops will be administered before the operation. Don’t worry, you will not feel any pain, but for your peace of mind please know that an anesthesiologist is present at all times taking care of your well-being.
Before the operation special laser called YAG laser is used to put a small hole into the iris (iridotomy). This is necessary to allow the aqueous humor (a liquid inside the eye) to continue to flow freely between the anterior and the posterior chamber after surgery, since the additional lens might impair this circulation. It is a measure of precaution to prevent a rise of the intraocular pressure inducing secondary glaucoma.
Step 1: performing microincisions in the cornea allowing the introduction of the instrument necessary to insert the lens. Application of a gel-like substance to protect the structures of the eye during the insertion of the lens (this gel is removed at the end of the procedure).
Step 2: Folding of the ICL and insertion from a cartridge through the microincisions.
Step 3: The lens unfolds by itself inside the eye and is placed directly behind the iris.
Step 4: At the end of the procedure no sutures are needed for the corneal incisions. They will heal quickly with the cornea recovering its natural shape.
To increase your comfort and for additional protection, the surgeon might place a patch over your eye for the first day after the intervention. It will be removed the next day at the first postoperative examination. It is very important to keep this appointment, because the intraocular pressure has to be controlled and the eye’s general condition checked.
You absolutely must strictly follow the guidelines indicated by your surgeon, especially those related to the antibiotic and anti-inflammatory eyedrops that have be administered during the days after surgery.
