PURPOSE To determine the feasibility of using posterior chamber phakic intraocular lenses (PIOLs) to treat high myopia, comparing two different models, Staar and Adatomed. METHODS Twenty-four eyes from 12 patients were studied prospectively. A phakic Staar IOL was implanted in one eye of each patient, and the other eye received a phakic Adatomed IOL. Patients with uveitis or ocular trauma pri...

The development of retinal detachment is reported in three eyes, of two patients, following implantation of an anterior chamber intraocular lens (AC-IOL) in phakic eyes for the correction of ultra-high myopia. The presence ofan AC-IOL may hamper the identification of retinal breaks and removal of the intraocular lens may prove necessary to improve visualisation. Shallowing of the anterior chamb...

The primary goal of refractive surgery is the smallest residual refractive error and preserved contrast sensitivity with the same visual capacity under bright and dim illumination. Corneal refractive surgery cannot correct very high ametopias; from -10 to -14 D is the limit of myopia correction in the cornea and from +4 to +6 D, the limit of hyperopia correction. Intraocular refractive surgery ...

OBJECTIVE To analyze the surface quality of new generation phakic intraocular lenses (IOLs). DESIGN Experimental materials study. MATERIALS Three different new generation phakic IOLs: angle-fixated anterior chamber lens Chiron Vision NuVita MA20 (polymethylmethacrylate [PMMAD, iris-fixated anterior chamber lens Ophtec Artisan Iris-Claw (PMMA), posterior chamber lens Staar ICM (polymer from ...

PURPOSE To evaluate the functional and the anatomical outcomes after implantation of phakic posterior chamber intraocular lenses (IOLs) in highly myopic eyes. SETTING Service d'Ophtalmologie, Hôpital Purpan, Toulouse, France. METHODS Fifty-eight eyes of 46 patients that had implantation of phakic posterior chamber lenses for high myopia were evaluated. Predictability, efficiency, safety, an...

Posterior Chamber Phakic Toric Implantable Collamer Lenses have become increasingly used to correct refractive error associated with astigmatism. These devices are claimed to provide high efficacy in terms of refractive correction. This book chapter is an updated review on the safety and effectiveness and potential complications of the toric implantable collamer lens (Toric ICL) published in pe...
