The implantable collamer (ICL) is an optical element similar to a contact lens and it is permanently implanted behind the iris. It does not require any maintenance or exchange. It is a suitable solution for younger patients with high prescriptions, both plus and minus ones.
The surgery takes about 10 minutes. The implantation is a two-step process.
In the first step, the patient comes to Prague for a preoperative examination. As the lens is tailor-made for each patient, a deposit for the lens needs to be paid before the order takes place. This first visit only takes one day, the patient can fly back home immediately after the examination. Six weeks later, the lens is ready to be implanted. If only 1 eye is to be treated, the patient stays in Prague 2 days, in the case of both eyes the patient stays 4 days.
ICL phakic lens is a great alternative beyond the scope of a laser eye surgery. Because the Visian ICL is placed behind the iris, it is undetectable to the naked eye. ICL phakic lens can correct higher refractive errors. Another advantage is the possibility to change the lens in case the disorder progresses.
The ICL Lenses Characteristics
ICL is produced by STAAR, a Swiss company, and has been approved for use by the European Union and the US FDA. It is also referred to as VisianICL in some countries. Visian ICL is positioned behind the iris and in front of your natural lens. The Visian ICL (Implantable Collamer® Lens) is one of the latest technological advancements in vision correction technology. The Visian ICL is made from Collamer, a 100% biocompatible material created and used exclusively by STAAR Surgical.
This technology is able to treat a large range of refractive error varying by region; it is FDA approved to correct myopia in adults ranging from -3.0D to -15.0D with less than or equal to 2.5D of astigmatism at the spectacle plane and can reduce myopia in adults ranging from greater than -15.0D to -20.0D with less than or equal to 2.5D of astigmatism at the spectacle plane. As for hyperopia, up to + 20D can be treated.
