As we continue to navigate the scale and impact of COVID-19, the health and wellbeing of our staff and patients is always our greatest priority. We have therefore made the difficult decision to stop seeing non-urgent patients but will continue to offer support through video consultations.
Visian ICL (Implantable Collamer Lens) is a type of lens that is surgically implanted into the eye to correct refractive errors. An alternative to laser eye surgery for very short-sighted patients, the Visian ICL works like a contact lens – but because it is surgically implanted, it cannot be felt inside the eye, and because it’s a permanent vision correction solution, it eliminates the need for patients to remove or replace lenses every day.
The procedure to insert an intraocular lens (IOL) such as the Visian ICL is known as Phakic IOL. It’s a safe and quick operation done under local anaesthetic, using keyhole surgery to make a tiny incision and implant the lens.
The Visian ICL is a soft lens made from collamer, a material that can be folded easily in order to implant it safely into the eye. During surgery, it is inserted behind the iris. The natural lens remains in place, with the Visian ICL positioned in front of it.
Visian ICL has several benefits and, for some patients, may be a better choice than LASIK or other forms of laser eye surgery:
Some of the language around implantable lenses can be a little technical. Use this quick guide to help you cut through the jargon.
The procedure to insert the Visian ICL is painless and typically takes just 10-15 minutes. The resulting improvement in vision can be dramatic. Once inserted, the lens cannot be felt inside the eye.
