Cataract Surgery Dataset for Eye Positioning and Alignment

Computer-assisted intraoperative intraocular lens (IOL) positioning and alignment is a valuable study. It is important to precisely position and align the axis of IOL during surgery to achieve optimal post-operative astigmatism correction. The cataract surgery dataset is proposed in the research paper “Computer-aided Intraoperative Toric Intraocular Lens Positioning and Alignment During Cataract Surgery”. Videos of 20 cataract patients under routine cataract surgery were collected from a tertiary eye hospital (Shanxi Eye hospital, Taiyuan, Shanxi, China) with a resolution of 1920 × 1080 pixels and a frame rate of 25 FPS. The videos of these patients were divided into three groups, 10 as the training set (Video 11-20), 3 as the evaluation set (Video 8-10) and 7 as the test set (Video 1-7). We used manual and PCS algorithm, the limbus detection algorithm proposed in the paper, to label the limbus of surgery images in the training set. The limbus and blood vessel bifurcation points near the limbus in the evaluation set and test set were manually labeled. This cataract surgery dataset can be used to develop and evaluate algorithms for eyeball rotation and positioning during cataract surgery.
