Learning curve assessment by the wet lab
iridodialysis
IRIDODIALYSIS
Twenty residents and 2 anterior segment attendings were recruited from the People’s Hospital of Guangxi Zhuang Autonomous Region Department of Ophthalmology. We studied the learning curve of the STF and DDT knotting modalities for resident microsurgical education through a wet lab. Residents were randomized into 2 groups, STF and DTT. The residents participated in a lecture that reviewed the proper suturing technique and explained the pupil suturing task, which consisted of passing 1 cardinal suture of the pupil border in porcine eyes with iridodialysis using 10–0 polypropylene sutures. The residents were provided 1–3 practice courses, which were performed at their discretion, before the suturing task. Each suture pass was objectively scored by 2 anterior segment attendings using the criteria shown in Table Suture test score deduction criteria
