Abstract: Objective To explore the scoring performance of expert and novice ophthalmologists in the cataract surgery module using the EyeSi surgical simulator. Methods A total of 10 senior attending or higher-level ophthalmologists(expert group)and 15 residents or junior attending ophthalmologists(novice group)from the Affiliated Eye Hospital of Nanchang University were recruited. Each participant performed three operations on the five items of the EyeSi cataract surgery module CAT-B(including capsulorhexis, hydrodissection, nucleus splitting and phacoemulsification, IA cortical aspiration, and intraocular lens implantation), with the highest score recorded for each item. Results In the 5 test items of the CAT-B module(capsulorhexis, hydrodissection, nucleus cracking and phacoemulsification, IA cortical aspiration, and intraocular lens implantation), the expert group scored higher than the novice group, with statistically significant differences(P<0.05 for all). The expert group achieved higher scores in key indicators such as capsulorhexis centrality, continuity, adequate fluid wave formation, ultrasound energy efficiency, thorough cortical removal, and accurate intraocular lens implantation. Meanwhile, they had fewer deductions in negative aspects like corneal endothelial damage, zonular damage, capsular rupture, and prolonged operation time. Conclusion The expert group outperformed the novice group in terms of accuracy, operational efficiency, and tissue protection. The EyeSi surgical simulator is capable of objectively evaluating the cataract surgery skills of ophthalmologists and can serve as an effective tool for standardized ophthalmic clinical training and assessment of cataract surgery teaching effectiveness.
