Implanting a foldable acrylic IOL using peripheral iris fixation can correct aphakia in eyes that do not have adequate capsule support, according to a study published in the July issue of Ophthalmology. The technique also appears to be associated with few severe adverse events, the study authors noted.

Garry P. Condon, MD, and colleagues reviewed outcomes for 46 patients implanted with a three-piece foldable acrylic IOL using modified McCannel iris suture fixation. Capsule support was absent in all eyes, according to the study.

The researchers found that best corrected visual acuity significantly improved from 20/100 preoperatively to 20/50, and 97% of eyes maintained or improved BCVA at 24.1 months mean follow-up. Three cases (6.5%) experienced low-grade uveitis, three (6.5%) experienced transient pigment dispersion, two (4.3%) experienced IOL dislocation, one (2.2%) had an elevation in IOP and one (2.2%) developed a retinal detachment, the authors reported.

"No new cases of cystoid macular edema or worsening of glaucoma occurred," they noted.
