Phakic intraocular lens

(重定向自PIOL)
Photo of an eye after PIOL-implantation, 24 hours after surgery. The lens is visible in front of the iris, the pupil is still small due to presurgery eyedrops.

Phakic intraocular lens (PIOL) is a special kind of intraocular lens that is implanted surgically into the eye to correct myopia (nearsightedness). They are called "phakic" because the eye's natural lens is left untouched. This is in contrast to intraocular lenses that are implanted into eyes after the eye's natural lens has been removed during cataract surgery.
