Surgical Results of Artisan Lens Implantation in the Posterior Chamber of Eyes Lacking Capsular Support

Abstract

Abstract: : Purpose: Transscleral suturing of posterior chamber (PC) intraocular lenses (IOLs) is commonly done in aphakic eyes lacking capsular support. This technique, however, is time–consuming and has potential complications including vitreous hemorrhage and lens tilting. To avoid these problems, we have used Artisan IOLs in such eyes. Methods: Artisan IOLs (model 205, Ophtec) were implanted in 49 eyes of 49 patients (26 men, 23 women, 36–90 year–old). In each eye, a 5.5–mm corneal or corneoscleral incision and two side ports (3 and 9 o’clock) were made. When necessary, an anterior vitrectomy was performed followed by an injection of acetylcholine chloride into the anterior chamber (AC). After filling the AC and posterior chamber (PC) with hyaluronic acid, the IOL was inserted into the PC through the miotic pupil. The IOL was fixed to the iris at the 3 and 9 o’clock position in most cases. Results: The surgery was performed in all cases without any complications. The pre– and postoperative mean corneal endothelial density were 2396 ± 822 and 2322 ± 750 (mean ±S.D. /mm²), respectively. Postoperatively, the IOLs were securely positioned in the PC except for one eye. In this eye, one claw had come off the iris approximately 3 months postoperatively probably because on of the claw had been damaged during the initial procedure. No other adverse effects were observed with a mean follow–up of 10.6 months. Conclusions: Implantation of the Artisan IOL in PC is most likely safe and effective in eyes lacking capsular support, although further studies on more eyes with longer follow–up periods are necessary.
