摘要

Purpose: To describe the demographic data, evaluate the longterm refractive and anatomical outcomes, and report the incidence of complications of anterior iris (prepupillary) and posterior iris (retropupillary) fixation of the Artisan aphakia iris-claw intraocular lens (IOL).
Setting: Complejo Hospitalario Universitario de Santiago de Compostela, Spain.
Design: Retrospective case series.
Methods: Patients who had iris-claw IOL implantation were divided into 2 groups: Group 1 (prepupillary) and Group 2 (retropupillary). The corrected distance visual acuity (CDVA), anatomical changes, endothelial cell count (ECC), presence of cystoid macular edema (CME), and operative and postoperative complications were determined.
Results: The study comprised 95 eyes of 95 patients. Fiftyseven patients had prepupillary implantation and 38 patients had retropupillary implantation. Indications for surgery were IOL luxation or subluxation (n = 24), lens luxation or subluxation (n = 17), trauma (n = 15), aphakia (n = 30), and other (n = 9). The CDVA improved significantly in both groups and there were no differences between them. A significant ECC reduction was observed in both groups, with no differences between them. The incidence of CME was 16.1% (21.8% in the prepupillary group and 7.9% in the retropupillary group at 3 months and 8 months, respectively), although the difference was not statistically significant. Other postoperative complications were rare and no differences were found between groups.
Conclusions: Irrespective of location, the iris-claw IOL provided good visual outcomes with few complications. However, prepupillary IOL implantation seemed to contribute to greater endothelial cell loss and earlier onset of CME.
