A phakic intraocular lens (PIOL) is an intraocular lens that is implanted surgically into the eye to correct refractive errors without removing the natural lens (also known as "phakos", hence the term). Intraocular lenses that are implanted into eyes after the eye's natural lens has been removed during cataract surgery are known as pseudophakic.
A phakic IOL. An intraocular lens (IOL) is a lens implanted in the eye usually as part of a treatment for cataracts or for correcting other vision problems such as near-sightedness (myopia) and far-sightedness (hyperopia); a form of refractive surgery.
These lenses are called angle-supported because the footplates of the lens rest in the irido-corneal angle. Current [ when? ] models of angle-supported phakic IOLs include: Acrysof AC, Phakic 6, Kelman-Duet, I-Care, ZSAL-4, Vivarte and NuVita.
Phakic intraocular lens implantation inside the eye can also be used to change refractive errors. The newest type of intervention is a type of PIOL called the implantable collamer lens which uses a biocompatible flexible lens which can be inserted in the eye via a 3 mm incision. The ICL is used to correct myopia ranging from −0.5 to −18 ...
Additionally, many of these people have reached the age where presbyopia occurs. Some also develop cataracts. Their vision can still be restored with Epi-LASIK, photorefractive keratectomy, LASIK or phakic lens extraction, or cataract surgery. The corneal curvature has to remeasured and modified by history, central keratometry, or contact lens ...

Iris-fixated intraocular lens is an intraocular lens that is implanted surgically into the eye and attached to the iris. Originally developed for aphakia, phakic versions have also been produced to correct myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. They are suited for correction of eyes where corneal refractive ...
Phakic IOL: Phakic intraocular lens are lenses that implanted inside eye without removing the normal crystalline lens. Phakic IOLs can be used to correct hypermetropia up to +20 diopters. [22] Non laser procedures
