Single-Haptic Dislocation of Retropupillary Iris-Claw Intraocular Lens: Outcomes of Reenclavation

Abstract

Background and objective: To report the clinical feature of dislocated retropupillary iris-claw aphakic intraocular lens (IOL) and outcomes of reenclavation.

Patients and methods: In this multicenter, retrospective case series, 225 eyes of 225 patients underwent retropupillary fixation of iris-claw aphakic IOL and the cases with haptic dislocation were reviewed.

Results: Single haptic dislocation was observed in 22 of 225 eyes (9.8%) after 89 ± 77 days (range: 5 days to 277 days) postoperatively, and resolution was achieved through reenclavation without any intraoperative complications in all patients. Iris atrophy in 13 eyes (59%) and history of face washing at the time of dislocation in five patients (23%) were noted. Reenclavation did not cause statistically significant change in best-corrected visual acuity (P = .315), spherical equivalent (P = .660), or endothelial cell count (P = .182) compared to those after the primary surgery.

Conclusion: Single-haptic dislocation of retropupillary iris-claw aphakic IOL is not a rare complication and can be safely and effectively corrected by reenclavation.
