Controlling a laser surgical device with a sensation generator
Last updated:
Abstract:
In certain embodiments, a system for controlling a laser device comprises a laser device, a distance meter, a haptic sensation generator, and a computer. The laser device generates a laser beam with a focal point. The distance meter measures a distance between the focal point and a target of an eye of a patient. The haptic sensation generator generates an acoustic field that projects a sensory pattern onto a user. The computer: receives the distance from the distance meter; determines the pattern corresponding to the distance according to a function in which the distance is a variable; and instructs the haptic sensation generator to generate the acoustic field that projects the determined pattern.
