title: Video-Assisted Informed Consent for Cataract Surgery: A Randomized Controlled Trial.
abstract: Purpose. To investigate whether adding video assistance to traditional verbal informed consent advisement improved satisfaction among cataract surgery patients.Methods. This trial enrolled 80 Chinese patients with age-related cataracts scheduled to undergo unilateral phacoemulsification surgery. Patients were randomized into two groups: the video group watched video explaining cataract-related consent information and rewatched specific segments of the video at their own discretion, before receiving traditional verbal consent advisement; the control group did not watch the video. Outcomes included patient satisfaction, refusal to consent, time to complete the consent process, and comprehension measured by a ten-item questionnaire.Results. All 80 enrolled patients signed informed consent forms. Compared with the control group, members of the video group exhibited greater satisfaction (65% versus 86%,p= 0.035) and required less time to complete the consent process (12.3 ± 6.7 min versus 5.6 ± 5.4 min,p< 0.001), while also evincing levels of comprehension commensurate with those reported for patients who did not watch the video (accuracy rate, 77.5% versus 80.2%,p= 0.386).Conclusion. The video-assisted informed consent process had a positive impact on patients' cataract surgery experiences. Additional research is needed to optimize patients' comprehension of the video.
