For people with moderate to high myopia or thin corneas which cannot be treated with LASIK or PRK, the phakic intraocular lens is an alternative.
It has been largely supplanted by newer, more accurate operations, such as photorefractive keratectomy, LASIK, Epi-LASIK and the phakic intraocular lens.
In 1986, Fyodorov designed the first posterior chamber phakic IOL in the "collar-button" or "mushroom" configuration and manufactured the pIOL from silicone.
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).
However, phakic patients undergoing trabectome showed a greater reduction in intraocular pressure, compared to patients undergoing phacoemulsification combined with trabectome.
Originally developed for aphakia, phakic versions have also been produced to correct myopia (nearsightedness), hyperopia (farsightedness), and astigmatism.
