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. Phakic intraocular lenses, or Phakic lenses, are lenses made of plastic or silicone that are implanted into the eye permanently to reduce a person’s need for glasses or contact lenses. They are implanted in front of the natural lens. Phakic intraocular lenses are indicated for patients with high refractive errors when the usual laser options for surgical correction (LASIK and PRK) are contraindicated. Phakic intraocular lenses are contraindicated in patients who do not have a stable refraction for at least 6 months or are younger than 18 years of age.
For most people, breaking, losing, or misplacing their glasses is an annoying inconvenience. Not wearing glasses or contacts meant not seeing at all. Phakic intraocular lenses are surgically implanted in the eye in front of the natural lens bending light rays onto the retina to form a clear image.
PIOLs have the advantage of treating a much larger range of myopic and hyperopic refractive errors than can be safely and effectively treated with corneal refractive surgery. The PIOL is removable; therefore, the refractive effect is theoretically reversible. When compared with clear lens extraction or refractive lens exchange the PIOL has the advantage of preserving natural accommodation.
