Analysis of the quality and reliability of trifocal intraocular lens videos on YouTube

Abstract

This study analyzed the quality and reliability of videos on YouTube as educational resources on trifocal intraocular lenses (IOL). This study is a retrospective, cross-sectional and record-based study. An online YouTube search was performed using the terms "trifocal lens implants" and "trifocal IOL," and a total of 229 videos were recorded. Eighty-six videos that met the study criteria were included. All videos were evaluated with DISCERN, Journal of the American Medical Association (JAMA), and Global Quality Score (GQS) scores. The mean DISCERN, JAMA, and GQS scores were 37.79±11.92, 2.01±0.87, and 2.17±1.01, respectively. Of all the videos, 39 (45%) were uploaded by physicians, and 47 (55%) were uploaded by non-physicians. While the length of the videos (length) was significantly greater in the physician group (P=0.02), the age of the videos (age) was significantly higher in the non-physician group (P=0.02). However, the differences between the two groups in terms of other general characteristics, DISCERN, JAMA and GQS scores were not significant. Our finding suggests that trifocal IOL-related YouTube™ videos are of low quality and reliability, thus inadequate for patient information.
