Implanting phakic IOLs (PIOLs) in phakic eyes is regarded as an established option in refractive surgery for many years when treating high myopia, hyperopia or ametropia. Even for eyes which show a combination of refractive errors (including astigmatism) this can be an appropriate option. The surgery itself requires certain anatomical and refractive requirements, since, as with any intraocular procedure, there are different possibilities of complication depending on the chosen IOL.

Refractive surgery includes all procedures which are primarily targeted at changing the refractive power of the eye. Currently laser-assisted in situ keratomileusis (LASIK) is indicated to correct myopia of up to - 8 D, hyperopia up to + 3 D and astigmatism up to 5 D. Photorefractive keratectomy (PRK) and laser epithelial keratomileusis (LASEK) are primarily recommended for myopia up to - 6 D and for greater refractive errors, phakic intraocular lenses (IOL) are the first choice (myopia greater than - 6 D and hyperopia greater than + 3 D).

In 1986, the concept of the claw lens was applied to correct myopia in phakic patients. Since then, progress has made iris-fixated phakic intraocular lenses (IOL) relatively safe, predictable, and effective for the correction of myopia, hyperopia, and astigmatism. All these models have undergone a series of design improvements to prevent complications. Read More

Perfect tolerance is expected when one implants a phakic intraocular lens (pIOL) in the anterior segment. Not only should the material be compatible, but the pIOL must respect the anatomy of the anterior chamber. Based on 3 years of experience using an anterior segment optical coherence tomographer (Visante OCT, Carl Zeiss Meditec), I have defined numerous safety criteria for pIOLs. Read More
