Chung AT, et al. – Analysts ascertain the impact of fine motor activity and nondominant–hand training on cataract surgical simulator (Eyesi) performance. Regular video game play enhanced baseline microsurgical performance measured on the surgical simulator. Simulation performance improved significantly in the intervention group and control group after 1 session on the simulator. Although not statistically important, training the nondominant hand with daily activities demonstrated a trend toward improved navigation and bimanual performance.
