Implantable contact lenses (IOLs), or phakic intraocular lenses, are contact lenses that can be implanted into the eye. The lenses were developed for patients with high levels of nearsightedness and minimal amounts of astigmatism. Phakic IOLs are implanted either in front of or behind the iris (the colored part of the eye.)

Surgeons at the Moran Eye Center were part of the original clinical trials for this procedure and have been working with the lenses since 1997.

Approved Correction Levels

This procedure was originally approved for very high corrections up to -20.00 diopters. These lenses are now approved for use in patients with correction -3.00 diopters to -20.00 diopters of correction, with limited amounts of astigmatism.

How Implantable Contact Lenses Work

Types of Implantable Contact Lenses

There are two available lens options. Your surgeon will determine if you are a candidate and discuss the best option for your eyes during your refractive screening session.

Visian ICL (Implantable Collamer Lens) - This lens is placed through a small incision in the eyes directly behind the iris and in front of the lens. The Visian ICL is made from soft plastic and collagen-based material that is well tolerated in the eye. It has been used safely and effectively to correct myopia between -3 diopters to -15 diopters.


Verisyse Lens - This lens is placed in front of your natural lens and is clipped to the colored part of the eye (iris). The Verisyse lens is made from PMMA material that is well tolerated in the eye. It is about one-fourth size of your fingernail, making it almost undetectable to the naked eye. It has been used safely and effectively to correct myopia between -5 diopters to -20 diopters.
