Abstract Body: 

Purpose: Risk communication is an integral aspect of shared decision‐making and evidence‐based patient choice. There is currently no standardized or recommended way of communicating the risks and benefits of cataract surgery to patients, as it is usually up to each ophthalmologist’s discretion. This study aims to investigate whether the way this information is presented influences patients’ perception of how risky surgery will be. 

Study Design: Two‐arm parallel randomized experimental design. 

Methods: Patients referred for cataract surgery who have not yet made their decision to undergo surgery were considered for this study. Patients were randomly assigned to one of two study groups (positive or negative framing). Then, a brief questionnaire including sociodemographic variables (age, sex, education), prior cataract surgery knowledge, and visual satisfaction was administered. According to their assigned study group, the risks of cataract surgery were then communicated to patients using either positive framing (99% chance of no side effects) or negative framing (1% chance of side effects). Patients then rated their perceived risk of experiencing surgical complications on a scale ranging from 1 (not at all likely) to 6 (very likely). The responses were analyzed to identify significant differences in patient scores among 
study groups as well as other potential drivers of change in scores. 

Results: This study included a total of 60 patients, 30 in each study group, majority of patients were female (70% in the positive framing group and 57% in the negative framing group), and the mean age was 70±10 years and 72±9 years, respectively. Median (IQR) risk perception was 2 (1‐2) in the positive framing group and 3 (2‐ 3) in the negative framing group. Statistically significant difference was found between the groups (p=.0007). There was no significant difference in risk perception by sex per study group (p=.24 and p=.17), education (p=.71 and p=.26), visual satisfaction (p=.8 and p=.45), and prior knowledge (p=.39 and p=.2). Age did not significantly predict risk perception (r 2= .0004 and p=.88). No correlation was observed between risk perception and waiting time between referral and cataract consultation (r 2=.008 and p=.5) 

Conclusions: Patients who received positive framing reported lower risk scores for cataract surgery than patients who received negative framing. Sociodemographic factors were not identified as significant drivers of change in patients’ perceived risk. A larger sample size is needed to further investigate.
