The Clinical Results of Iris-Fixed Phakic IOL

Purpose: To prospectively evaluate the clinical results of iris-fixed phakic intraocular lens (IOL) implantation (Artisan? implantation) in patients with high myopia. Methods: Eighteen eyes of 10 patients underwent Artisan? implantation between December 2001 and February 2003 and were followed up for more than 6 months. The study prospectively analyzed the efficacy, safety and predictability of Artisan? implantation based on visual acuity and refractive errors. Results: The preoperative mean uncorrected visual acuity (UCVA) was 0.02, and mean spherical equivalent refraction was -9.98D. Postoperative uncorrected vision was more than 0.5 in 83.3% of the eyes at 1 month and in 100% after 3 months. Also it was more than 0.9 in 22.2% of the eyes at 1 month, in 50.0% at 3 months and in 88.9% at 6 months. The spherical equivalent refraction after surgery was within 0.5D of emmetropia in 77.8% of eyes at 1 month, in 94.4% at 3 months and in 100% at 6 months. Also it was within 1.0D of emmetropia in 94.4% at 1 month and in 100% after 3 months. Complications included temporary glare or halo in 3 eyes, transient elevation of intraocular pressure in 1 eye, and decentration of IOL due to incomplete iris-fixation in 1 eye. Conclusions: Because of its good visual results and rare complications, the Artisan? implantation may be an effective surgical procedure for patients who cannot undergo laser in situ keratomileusis (LASIK).
