Iris-fixated IOL improves vision in aphakic eyes with insufficient capsule support
Secondary implantation of an iris-fixated IOL can be performed in aphakic eyes that lack adequate capsule support, according to a study.
The study authors noted that good long-term outcomes were achieved in Asian patients and that implantation of this lens may make it unnecessary to perform peripheral iridectomy in aphakic eyes.
The prospective cohort study included 72 eyes of 72 patients who underwent implantation of the Artisan IOL (Ophtec) at two centers in China. Mean patient age was 57.5 years.
Subjective refraction, uncorrected and corrected distance visual acuity, keratometry, IOP, endothelial cell density and fundus images were evaluated preoperatively and at 1 week, 1 and 6 months, and 1, 2 and 3 years after surgery. Surgically induced astigmatism was also evaluated.
Mean preoperative uncorrected distance visual acuity was 1.18, mean preoperative corrected distance visual acuity was 0.29, and mean preoperative spherical equivalent was 11.65 D. Mean preoperative endothelial cell density was 2,753.88 cells/mm2.
Study results showed that at 3 years, uncorrected distance visual acuity improved significantly in all eyes (P < .05). Fifty-three eyes (73.6%) achieved 20/40 or better.
Mean spherical equivalent was –0.58 D; the improvement was statistically significant (P < .05). Spherical equivalent at final follow-up was within 1 D of targeted refraction in 63 eyes (87.5%).
Mean endothelial cell loss was 9.78% at 3 years, the authors said.
