what is phakic intraocular lens (piol) technology?

At Clarity Laser Vision, we believe that intraocular surgery can provide an excellent surgical outcome for certain situations. For patients, younger than 40 and are not good candidates for LASIK or PRK, they may benefit from having Phakic Intraocular Lens (PIOL) where an artificial intraocular lens is placed inside the eye over the natural lens. Although there are slightly higher risks with performing intraocular surgery, in the hands of an experienced surgeon the risks are quite low.

what type of piol lenses are there?

There are currently two approved Phakic IOL technologies approved: The Visian ICL ™ and ARTISAN® Phakic IOL. The Visian ICLTM (Implantable Collamer Lens) is a lens that is permanently implanted in the eye behind the iris and in front of the natural lens. It is called a phakic intraocular lens (IOL) because the eye still has its natural lens. The Visian ICLTM has been approved by the Food and Drug Administration (FDA) for the treatment of patients with moderate to severe near-sightedness (myopia). The Visian ICLTM is approved for treatment of myopia between the ranges of -3 diopters to -20 diopters, with up to 2.5 diopters of astigmatism.

The ARTISAN® Phakic IOL is an intraocular lens that is inserted in front of your natural lens, between the cornea and the iris, during a surgical procedure. This type of lens is called a phakic IOL, because the eye still has it natural lens in place. The IOL is made of the same type of plastic that has been used to make intraocular lenses for cataract surgery. The plastic has a long history of use in these types of products. The goal of placing the ARTISAN® Phakic IOL into your eye is to correct your nearsightedness.

Dr. Al-Ghoul will select the appropriate lens power (diopter) to correct your nearsightedness. Once the ARTISAN® Phakic IOL has been implanted in your eye and your eye has healed, the light coming into your eye can correctly focus on the retina, resulting in improved vision. The ARTISAN® Phakic IOLis approved by the Food and Drug Administration for treatment of myopia between the ranges of -5 diopters to -20 diopters, with up to 2.5 diopters of astigmatism.

Choosing between the two technologies is a decision only your surgeon can make based on your unique eye measurements.
