Abstract Details


To assess whether pseudoexfoliation alone or in correlation with other risk factors is associated with intraoperative cataract complications


2nd Ophthalmology Department, Aristotle University of Thessaloniki, Thessaloniki, Greece


In a retrospective cohort study, medical records of 1502 patients undergone phacoemulsification surgery were reviewed and exclusion criteria were applied. In the time of interest (01/01/2014-31/12/2015), patients were assessed preoperatively and all qualitative and quantitative characteristics of the eligible patients were gathered and processed according to our stratification system.


In overall 1792 eyes, pseudoexfoliation was present in 12.7% (227 eyes). In a multivariable regression analysis pseudoexfoliation had an Odds Ratio of 0.48 (p=0,022), appearing as a protective factor. Correlations between dense cataracts, poor pupillary dilation, zonular weakness, age, gender and open-angle glaucoma were made and the level of statistical significance was set at 0,05.


The geographic distribution of PEX is favoring surgeons to familiarize and master the techniques needed to prevent complications in the existence of such factor. A modification to the stratification system used should include the reduction of the risk assessment at least for the regions of wide distribution of the factor.
