ICL Informational Videos

Implantable collamer lenses (ICLs), also known as phakic IOLs, correct vision in much the same way that external contact lenses do, except ICLs are surgically placed inside the eye, where they permanently improve vision. Phakic, from the Greek word “phakos,” for lens, refers to artificial lenses that operate in conjunction with the patient’s natural lenses.

While ICLs function in almost exactly the same way as contact lenses that sit atop the eye, they are also similar to intraocular lenses (IOLs), which are used during cataract surgery to replace the eye’s natural lens after it has been fragmented and removed. However, during ICL surgery, the natural lens is kept in the eye and works with the implanted lens to correct vision.

ICLs are inserted through tiny incisions in the cornea and placed behind or in front of the iris (The colored part of the eye) and in front of the natural lens. These thin, pliable lenses can serve as an alternative to laser eye surgery procedures such as LASIK and are often used to correct conditions that laser procedures may be unable to correct, such as extreme myopia. The ICL procedure produces little to no discomfort for the patient and has a 95 percent average success rate.
