Three-year follow-up of the artisan phakic intraocular lens for hypermetropia☆
Received 9 October 2001; accepted 13 December 2002.
Abstract
Purpose
We report the postoperative results of the Artisan Hyperopia phakic intraocular lens (IOL; model 203W; Ophtec, Groningen, The Netherlands).
Design
Prospective, nonrandomized trial.
Participants
Twenty-six eyes of 13 self-selected patients with refractive error ranging from +3.00 to +11.00 diopters (D).
Intervention
Patients with hypermetropia were implanted with the Artisan Hyperopia phakic IOL. Mean follow-up was 22.4 months (range, 3–36 months).
Main outcome measures
Predictability, stability, efficacy, loss of best spectacle-corrected visual acuity, and complications.
Results
At six months, 90.9% (20 of 22 eyes) were ±1.00 D of intended correction and 81.8% (18 eyes) were ±1.00 D of emmetropia. The mean spherical equivalent was stable within 0.25 D during the entire 3-year follow-up period. Twenty-four eyes (92.3%) had a postoperative best spectacle-corrected visual acuity of 0.50 or better at all of their individual follow-up examinations. No patient lost 2 or more lines after the procedure. There was a significant negative correlation between anterior chamber depth and endothelial cell loss. Two patients experienced posterior synechiae with pigment deposits in both eyes. One of these patients had convex irides and underwent implant removal within 2 years with a consequent clear lens extraction and posterior chamber lens implantation.
Conclusions
Implantation of the Artisan Hyperopic lens leads to accurate and stable refractive results with no significant loss of vision. More attention should be paid to convex irides and shallow anterior chambers during the preoperative screening to avoid unnecessary complications.
