To assess the clinical features and outcomes of patients referred for management of dropped lens fragments during cataract surgery. METHODS: The medical records of 22 eyes from 22 patients who were referred to our hospital to undergo pars plana vitrectomy (PPV) for management of dropped lens fragments after phacoemulsification surgery at private clinics were reviewed. Data including patient demographics, preoperative and postoperative visual acuity, factors associated with dropped lens fragment, and postoperative complications were recorded. The factors were compared between 2 patient groups: postoperative Snellen acuity of 0.5 or better and acuity less than 0.5. The statistical significances of differences in factors between the 2 groups were calculated. RESULTS: The mean interval between cataract surgery and PPV was 2.6 +/- 3.7 days. At the final examination, the mean postoperative acuity was 0.57 +/- 0.20, and 16 eyes (72.7%) had a visual outcome of 0.5 or better. After excluding 7 eyes with other pre-existing ocular co-morbidities, 14 eyes (93.0%) achieved a final visual acuity of 0.5 or better. Multivariate analysis showed that the predictor for visual outcomes of 0.5 or better was absence of preoperative eye disease (p = 0.007). Complications after PPV included 2 (9.0%) cases of cystoid macular edema and 1 (4.5%) case of retinal detachment. CONCLUSIONS: Prompt referral and surgical management within 1 week for dropped lens fragments during cataract surgery may achieve a better visual outcome in cases with no pre-existing eye disease.
