Abstract
Purpose To determine the visual outcome, prognostic factors, and effect of timing of surgical intervention in patients with retained lens fragments after phacoemulsification.
Methods A retrospective review was carried out of the notes of 44 consecutive patients who suffered posterior dislocation of lens fragments during phacoemulsification, of whom 34 underwent vitrectomy.
Results The presence of severe uveitis at presentation was a significant predictor of a final visual acuity of less than 6/60 (p = 0.002). A raised intraocular pressure at presentation (> 29 mmHg) significantly increased the risk of chronic glaucoma (p = 0.0279), but there was no association between glaucoma and delay in vitrectomy. Patients operated on within 1 week of cataract surgery obtained a better visual outcome (64.7% of patients achieved 6/12 or better visual acuity) than those operated on later than 1 week (41% obtained 6/12), but this difference did not reach statistical significance.
Conclusions The trend towards a better visual outcome with early vitrectomy was not statistically significant. A large prospective trial is indicated to determine the optimum time for vitrectomy in these patients.
