Abstract
Purpose
To evaluate the visual outcomes of patients with zonular dialysis following cataract surgery.
Patients and methods
Medical records of all patients with documented zonular dialysis, either pre- or peri-operatively, undergoing cataract surgery between 2004-2010 at Queen Alexandra Hospital, Portsmouth, were retrospectively reviewed. Baseline demographics and biometry were analysed, and ocular co-morbidities documented. Intraoperative complications and the use of a capsular tension ring (CTR) were identified. Early and late best-corrected visual acuity (BCVA) post surgery were determined using LogMar values. Univariate and multivariate linear regression analysis was performed to determine associations with BCVA post surgery, and further subgroup analysis performed in groups determined by CTR use.
Results
The records of 22 312 consecutive eyes undergoing cataract surgery were reviewed. The incidence of zonular dialysis was 0.50% (111 eyes). A CTR was inserted in 46 eyes. Using a multivariate linear regression model, better initial pre-operative BCVA (P=0.019), the use of a CTR (P=0.014), and the absence of vitreous loss during surgery (P=0.008, β 0.45) were associated with improved early postoperative BCVA (mean follow-up 6.6 weeks). Better medium-term postoperative BCVA was significantly associated with preoperative BCVA (P=0.002) and the use of a CTR during surgery (P=0.004, β −0.41).
Conclusions
The overall incidence of zonular dialysis is low. CTR use intra-operatively suggests improved early and medium-term BCVA and should be considered in all cases of zonular dialysis.
