ABSTRACT

Objective: to evaluate the frequency, the prognostic factors and the impact of the intraoperative floppy iris syndrome in cataract surgery.
Method: a prospective and longitudinal cohort study of 139 cataract surgeries performed by the same surgeon, of which 49 eyes (35,3 %) presented with intraoperative floppy iris syndrome. An univariate/multivariate analysis was made taking on account demographic, personal history of pathologies, use of medications, anatomical characteristics of the iris, biometric parameters and complications during and after the surgery.
Results: in the univariate analysis, the significant prognostic variables for the intraoperative floppy iris syndrome were consumption of antipsychotics (p= 0,001), narrow anterior chamber (p= 0,001) and regular or bad dilated pupil (p= 0,001) before surgery. In the multivariate analysis, the narrow anterior chamber was, among all the independent variables, the most influential for the onset of the intraoperative floppy iris syndrome, with a highly significant association (p= 0,001). The intraoperative floppy iris syndrome increased the intra and postoperative risk for complications.
Conclusions: correct interrogation and an eye exam can predict the occurrence of intraoperative floppy iris syndrome during the cataract surgery. The use of antipsychotics, the narrow anterior chamber and regular or bad pupil dilation before the surgery can be considered as prognostic factors for the intraoperative floppy iris syndrome.
