Phakic
Phakic intraocular lens (PIOL) is a type of implantable lens that, unlike in cataract surgery, is placed over an existing natural lens. They are used in refractive surgery to correct myopia, and in some cases hyperopia and astigmatism.
Types[edit | edit source]
There are two types of phakic intraocular lens: anterior chamber and posterior chamber.
Anterior Chamber[edit | edit source]
Anterior chamber phakic intraocular lenses are placed in the anterior chamber of the eye, in front of the iris.
Posterior Chamber[edit | edit source]
Posterior chamber phakic intraocular lenses are placed behind the iris and in front of the natural lens.
Indications[edit | edit source]
Phakic intraocular lenses are used to correct refractive errors in the eye. They are an alternative to other corrective surgeries such as LASIK and PRK.
Risks[edit | edit source]
As with any surgical procedure, there are risks associated with the implantation of phakic intraocular lenses. These include cataract formation, glaucoma, retinal detachment, and loss of endothelial cells.
