About Phakic Intraocular Lenses
Phakic intraocular lenses, or phakic lenses, are lenses made of
plastic or silicone that are implanted into the eye permanently to
reduce a person’s need for glasses or contact lenses. Phakic
refers to the fact that the lens is implanted into the eye without
removing the eye’s natural lens. This is in contrast to
intraocular lenses that are implanted into eyes after the eye’s
cloudy natural lens (cataract) has been removed during cataract
surgery.
Ideally, phakic lenses cause light entering the eye to be focused
on the retina providing clear distance vision without the aid of
glasses or contact lenses.
During phakic lens implantation surgery, a small incision is made
in the front of the eye. The phakic lens is inserted through the
incision and placed just in front of or just behind the iris.
Phakic lenses are used to correct refractive errors, errors in the
eye’s focusing power. Currently all phakic lenses approved by the
FDA are for the correction of nearsightedness (myopia).
