Liquid loss detection during laser eye surgery

A laser eye surgery system that has a patient interface between the eye and the laser system relying on suction to hold the interface to the eye, the patient interface using liquid used as a transmission medium for the laser. During a laser procedure sensors monitor the level of liquid within the patient interface and send a signal to control electronics if the level drops below a threshold value. The sensor may be mounted on the inside of the patient interface, within a fluid chamber. Alternatively, a gas flow meter may be added to a suction circuit for the patient interface that detects abnormal suction levels indicating low fluid level.

Adjusting laser pulses to compensate for interfering objects
12029684 · 2024-07-09 · ·

In certain embodiments, an ophthalmic surgical system for performing a surgical procedure on an eye comprises a laser device, a camera, and a computer. The laser device comprises a laser source and a scanner. The laser source generates a laser beam comprising pulses, and the scanner directs the pulses towards tissue of the eye according to a laser focal spot pattern. The camera captures surgical images of the eye. The computer instructs the laser device to direct the pulses towards the eye according to the laser focal spot pattern, accesses and monitor the surgical images of the eye, identifies an interfering object from the surgical images of the eye, and modifies the control of the pulses to compensate for the interfering object.
