Abstract Details


To assess visual acuity outcomes and related factors after phacoemusification cataract surgery in eyes with good visual acuity preoperatively


Moorfields Eye Hospital, London, UK


This is a retrospective case series of patients undergoing phacoemulsification between the years 2008-2012 in Moorfields Eye Hospital NHSFT. Inclusion criteria were age≥40 years and pinhole visual acuity ≥6/9 preoperatively. Exclusion criteria were no postoperative visual acuity data.


2720 eyes were included in the analysis. The unaided logmar visual acuity improved from 0.54 to 0.18 (p<0.001), the logmar visual acuity with glasses improved from 0.34 to 0.06(p<0.001) and the logmar pinhole visual acuity improved from 0.15 to 0.13(p<0.001). 8.1% of patients had visual acuity ≤6/12 postoperatively. Mean follow up period was 23,6 days (sd=±9.9). In multivariate logistic regression, factors associated with visual acuity ≤6/12 postoperatively were: age (p<0.001), vitreous loss (p=0.002) and iris trauma (p=0.02).


Visual acuity improved significantly overall in this study group of patients, although 8.1% of them did not reach their pinhole preoperative visual acuity. Factors independently associated with worse visual acuity outcomes were increasing age, vitreous loss and iris trauma.
