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 assess the feasibility of using phakic intraocular lenses (PIOL) to treat high myopia, and evaluate the incidence of cataract, comparing three different lens types. METHODS From 1989 to 2002, we implanted three different phakic intraocular lenses (PIOL) in 343 eyes of 232 patients; 231 eyes recieved an Ophtec (Worst-Fechner model, iris-claw), 89 an Adatomed (silicone posterior cham...

This 30-year-old patient had a high myopia and with-the-rule astigmatism. Her best-corrected-visual-acuity was 20/20 with -6.75 -2.50 x 10. cornea an asymmetric bowtie, we were concerned laser vision correction. We then decided to implant toric phakic intraocular lens (Visian ICL® toric) and, 1 week after surgery, she J1 uncorrected. Note the central anterior vaulting of away from crystalline l...

PURPOSE To evaluate a digital high-speed camera combined with digital morphometry software for dynamic measurements of phakic intraocular lens movements to observe kinetic influences, particularly in fast direction changes and at lateral end points. MATERIALS AND METHODS A high-speed camera taking 300 frames per second observed movements of eight iris-claw intraocular lenses and two angle-sup...

purpose: to evaluate the efficacy and safety of the artisan phakic intraocular lens (piol) for the correction of high myopia. methods: in this prospective study of 22 eyes of 14 patients with high myopia, artisan piols (ophtec bv) were implanted. uncorrected visual acuity (ucva), best corrected visual acuity (bcva), refraction, astigmatism, safety, and predictability were analyzed. results: the...

PURPOSE To study in situ the intraocular position of the Artisan iris-claw intraocular lens (IOL) (model 203) (Ophtec) in phakic hyperopic eyes using ultrasound biomicroscopy (UBM). METHODS Echograms of the anterior chamber were taken preoperatively and 24 to 317 days postoperatively in 4 eyes implanted with the Artisan IOL (power +4.0 to +6.0 diopters). The preoperative anterior chamber dept...

Both choroidal neovascularization during pregnancy, and choroidal neovascularization following implantation of phakic intraocular lenses have been reported in the literature. To our knowledge, this is the first case reported of a gravid woman developing choroidal neovascularization in an eye with a phakic intraocular lens. A 31-year-old woman became aware of her pregnancy three weeks after plac...

OBJECTIVE To investigate iris perfusion in patients with and without pupil ovalization after phakic intraocular lens implantation. METHODS Comparative retrospective randomized case series of 6 participants, each with a regular pupil, and 6 participants with pupil ovalization after phakic intraocular lens implantation for high myopia were included in the study. Indocyanine green angiography wa...

PURPOSE To evaluate efficacy, predictability, and safety of Artisan toric phakic intraocular lens (Ophtec, Groningen, The Netherlands) implantation for the correction of astigmatism higher than 2 diopters. DESIGN Interventional case series. METHODS This prospective study included 27 eyes of 16 patients with a mean preoperative spherical equivalent of -11.78 +/- 6.24 diopters and a mean preo...
