Abstract

Abstract A system for controlling a plurality of ophthalmic microsurgical instruments connected thereto. The microsurgical instruments are for use by a user such as a surgeon in performing ophthalmic surgical procedures. The system includes a data communications bus and a user interface connected to the data communications bus. The user interface provides information to the user and receives information from the user which is representative of operating parameters of the microsurgical instruments. The system also includes surgical modules connected to and controlling the microsurgical instruments as a function of at least one of the operating parameters. The surgical modules are also connected to the data communications bus. The data communications bus provides communication of data representative of the operating parameters between the user interface and the surgical modules. Other features are also disclosed including a main control, an endo-illuminator system, a phacoemulsification handpiece, surgical scissors, a vitrectomy cutter, a surgical foot control, a remote control, a cart.
