More anterior capsular tears were seen after femtosecond laser-assisted cataract surgery than after phacoemulsification, according to a study.

Capsular tear occurred in 15 of 804 (1.87%) eyes that underwent femtosecond laser-assisted cataract surgery, whereas only one eye in 822 (0.12%) in the phacoemulsification group experienced such a tear, a statistically significant difference (P = .0002)between groups compared in the cohort case series.

No risk factors for capsular complications were identified in any patient who suffered a tear after surgery. In seven patients, IOL implantation in the sulcus was necessary after the tear widened to the posterior capsule.

Eye movement may compromise the integrity of the anterior capsulotomy in the laser-assisted cases, according to the study.

“Capsule specimens consistently showed ultrastructural features that may suggest a mechanical basis for weakness in capsular integrity induced by [femtosecond laser-assisted surgery], independent of the laser platform used,” the authors said.
