Control system for ophthalmic surgical instruments
First Claim
1. A microsurgical control system for controlling at least one ophthalmic microsurgical instrument for performing ophthalmic surgical procedures, the system comprising:
- a console;
connecting means for connecting at least one ophthalmic microsurgical instrument to said console;
control means coupled to said connecting means for providing a plurality of surgical procedure control signals to said instrument;
a first controller for displaying human readable characters at least a first portion of which are displayed at a first set of predetermined areas of said console and a second portion of which are displayed at a second predetermined area on said console;
a second controller adjacent one of said first and second predetermined areas of said console;
a third controller adjacent the other of said first and second predetermined areas of said console;
wherein at least one of said second and third controllers includes means for changing the human readable characters at a selected predetermined area; and
means for selecting the predetermined area at which the human readable character display and the corresponding control signals is to be changed.

Abstract
The control system is programmable by the user by inserting a preprogrammed key into the system console. The key changes the default values normally used by the control system to those values selected by a particular surgeon. The control console thus emulates the performance characteristics of a wide variety of different types of microsurgical control systems, leaving the surgeon free to perform the operation without having to adjust to a new or unfamiliar system. The display screen is self-illuminating and provides a plurality of control menus generated by data stored in computer memory circuits. By bank switching the memory circuits, the display can be caused to appear in a wide variety of different languages.
