AIM: To assess the incidence of vitreous loss and associated risk factors in residents performing manual small-incision cataract surgery(MSICS). METHODS: The present retrospective record review study was performed on 490 patients who underwent MSICS performed between November 2018 and December 2019 by 7 third-year postgraduate residents. The study group comprised of patients having intraoperative vitreous prolapse. All the surgeries were performed under supervision of a trained assistant. RESULTS: The mean age of the participants at the time of surgery was 68.42±2.05 y. Of the 490 patients, 250 patients were male, and 240 patients were female(P=0.23). A total of 215(43.9%) eyes had mature white cataract, 185(37.8%) eyes had brown cataract, and 90(18.3%) eyes had immature senile cataract. The incidence of intraoperative vitreous loss among residents was 2%(10/490). Vitreous loss occurred during hydrodissection [1/10(10%)], nucleus delivery [3/10(30%)], irrigation and aspiration [5/10(50%)], and intraocular lens insertion [1/10(10%)]. Multivariate stepwise Logistic regression analysis confirmed immature senile cataract [odds ratio(OR)=3.99;P=0.02], irrigation and aspiration of cortical material(OR=3.07;P=0.03), and anterior capsular extension(OR=3.22, P=0.03) as independent risk factors for vitreous loss. CONCLUSION: Immature senile cataract, irrigation and aspiration of cortical material, and anterior capsular extension are independent risk factors for vitreous loss. Our findings may serve as a guide for future trainers or residents learning MSICS.
