Abstract
A laser eye surgery system comprises subsystems which communicate with one another through low voltage differential signaling (LVDS). The laser eye surgery system may comprise a first subsystem interface, including an LVDS driver or transmitter coupled to and in communication with an LVDS receiver of a first subsystem of the laser eye surgery system. The first laser eye surgery subsystem itself may comprise an LVDS transmitter coupled to and in communication with an LVDS receiver to return data to the first subsystem. Further laser eye surgery subsystems may also include the same arrangement of drivers and receivers with respective subsystem interfaces. LVDS lowers power consumption and the risk of error in communication between laser eye surgery systems, leading to safer and more reliable surgical procedures performed.
