China OLIMPICS: China Ophthalmic Learning and Improvement Initiative in Cataract Surgery Trial

"Those in the intervention group will be introduced to a variety of simulation-based surgical training techniques. Specifically, this will involve breaking down the SICS cataract surgery procedure into stages, and practicing each stage repeatedly using simulation. This sustained deliberate practice will be integrated into the six-week course, as an enhancement to the course, and not as a replacement of any part of the educational content. Within the last three weeks of the course, 'intervention' arm participants will be introduced to the artificial eyes, the Simulation-OSSCAR rubric, and be provided with ongoing feedback.~All participants in both intervention and control arms will undertake the six-week Orbis-COS training course."

Standard surgical training (without bespoke training scheme using simulation and model eye). All participants in both intervention and control arms will undertake the existing six-week Orbis-COS training course, which includes 2-4 weeks of didactic lectures, surgical observation, and wet lab training with a minimum of 50 pig eye wet lab simulations per trainee. After observed mastery of wet lab pig eyes, trainees then perform hands-on training in county level hospitals. The hands-on training pairs a surgeon from the training centre to mentor the trainee through a minimum of 30 assisted surgeries and 50 independent surgeries under supervision.
