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

There are two types of phakic intraocular lens: anterior chamber and posterior chamber.

Anterior Chamber

Anterior chamber phakic intraocular lenses are placed in the anterior chamber of the eye, in front of the iris.

Posterior Chamber

Posterior chamber phakic intraocular lenses are placed behind the iris and in front of the natural lens.

Indications

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

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.
