Participants and data collection
iERM, visual impairment
EYE, LENS
This study retrospectively collected OCT images from iERM patients in Tianjin Medical University Eye Hospital (Tianjin, China) from July 2016 to December 2021. The patients’ gender, age, preoperative BCVA, duration of symptoms (e.g., progressive visual impairment and metamorphopsia), lens status, and 6-month postoperative BCVA were retrieved from the electronic medical records. The surgical process of VMP is shown in the online Supplementary Method Finally, 5,304 qualified OCT images were collected from 442 eyes (12 images from each eye). Specifically, 12 B-scans of each eye were seen as a whole, which was paired with patient data (BCVA). Subsequently, the images were randomized into a training dataset (265 eyes, 60.0% of all the eyes) for model development, a validation dataset (89 eyes, 20.1% of all the eyes) for parameter adjustment, and a testing dataset (88 eyes, 19.9% of all the eyes) for internal test and model evaluation.
