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 short sightedness and long sightedness; a form of refractive surgery. If the natural lens is left in the eye, the IOL is known as phakic, otherwise it is a pseudophakic lens (or ...
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. Neither have FDA approval yet.
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 ...
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
When the posterior capsule is damaged, the IOL may be inserted into the ciliary sulcus, [18] or a glued intraocular lens technique may be applied. [19] It is economical to use a rigid IOL if the incision size is already over 6 mm wide, but foldable IOLs can also be used if cost is not a limiting factor or incision size is <5 mm. [ 4 ]
The AMO portfolio already included the Amadeus II microkeratome, the Verisyse phakic IOL, and the ReZoom, Array and Tecnis IOLs. In Jan. 16, 2007 AMO announced the acquisition of privately held WaveFront Sciences Inc., a provider of wavefront diagnostic systems for refractive surgery and medical research, for $20 million in cash.
