Abstract: Clinic application study of robotic surgery is increasing in recent years. Robot assisted cataract surgery has the advantages of reducing the physiological tremor of the operator, improving the stability and accuracy of the operation, shortening the learning curve and so on. The surgical robot mainly assists in three key steps of cataract phacoemulsification, including continuous circular capsulorhexis, phacoemulsification and posterior capsule polishing. At present, a variety of robot assisted cataract systems play  roles in these key steps, such as Da Vinci surgical robot system, master-slave intraocular intervention surgical robot system, femtosecond laser assisted cataract surgery system, and optical coherence tomography mediated surgical robot system.
