Purpose-To determine whether a visual aid improves the understanding and retention of information presented during informed consent for rural, indigent patients presenting for cataract surgery.Materials and Methods-This was a randomized, unmasked, interventional study. We recruited patients who presented to the Hande Surgical Hospital in Chennai, India, for cataract surgery. Patients were randomized into two groups: verbal consent alone (group A) and verbal consent plus a poster (group B). Both groups completed an 11-question true/false quiz immediately before and after informed consent and one day after surgery.Results-A total of 60 patients were recruited for the study, with 30 randomly assigned to each group; 23 patients from group A and 17 from group B completed the study. Informed consent improved patient scores in both groups; however, group B had significantly higher mean scores on postoperative day 1 (7.4 vs 8.7, P = 0.005) and significantly greater improvement in mean scores from pre-informed consent to postoperative day 1 (1.3 vs 3.6, P = 0.002).Conclusions-Informed consent improves patient understanding of cataract surgery. Using a visual aid during informed consent for cataract surgery improves understanding and retention of information more than verbal consent alone in a rural South Indian population.Multiple barriers to high-quality care exist for millions of indigent patients with pressing medical conditions. [1][2][3][4] Ineffective communication between health care providers and patients is a major factor in reduced care. [5][6][7] Roadblocks to effective communication can include limited formal education, illiteracy, and misinformation or misunderstanding among the population being served regarding medical interventions. 5,7 Informed consent is a critical component of invasive medical procedures, helping to establish a healthy doctor-patient relationship by educating patients about the methods, risks, and benefits of procedures. 8 Moseley et al 9 examined the use of a poster and video presentation combined with a verbal informed consent in a highly educated population and demonstrated a significant increase in patient understanding of cataract surgery. In another study, the use of written pamphlets in addition to verbal discussion prior to cataract surgery showed an increase in information retention among patients. 10 Methods used to communicate with patients in developed countries such as graphic tools and electronic multimedia-based programs may not be applicable to indigent populations in the developing world. 11,12 In addition, written pamphlets and electronic programs can be prohibitively expensive in financially limited clinics. We aimed to determine whether a poster presentation combined with a verbal informed
