Double-Suture Scleral-Fixated Intraocular Lens With 2 Polypropylene Sutures.

PURPOSE: We present a modified technique in performing scleral fixation of a posterior chamber intraocular lens (IOL) using 2 pairs of double-armed 9-O polypropylene sutures and an ab-externo technique, in 2 patients with surgical aphakia after complicated cataract surgery.

METHODS

Two eyes of 2 patients underwent this modified technique by an experienced cataract surgeon (A.L.Y.) in 2022. We evaluated pre- and postoperative best-corrected visual acuity, perioperative complications, corneal endothelial cell density by specular microscopy, and IOL position by anterior segment optical coherence tomography and ultrasound biomicroscopy.

RESULTS

Both patients achieved an improvement in best-corrected visual acuity from 20/50 to 20/30 and 20/80 to 20/50, respectively. There was a loss in endothelial cell count in both cases (8% and 23%, respectively). No complications were noted in both cases, and postoperative anterior segment optical coherence tomography and ultrasound biomicroscopy showed a stable scleral fixation of IOL at more than 20 months postoperatively.

CONCLUSIONS

The utilization of 2 pairs of double-armed 9-O Prolene suture may provide a stronger alternative than conventional scleral fixation of IOL with single suture.
