    Abstract: The present disclosure provides a system and method for monitoring phototoxicity caused by vitreous visualization device ("VVD") illumination during ophthalmic surgery. The systems and methods determine the cumulative amount of optical energy incident on the retina, which corresponds to phototoxicity, the distance between a cutter of the VVD and the retina, and areas where the vitreous has been removed, or any combination thereof. The disclosure further provides a method for monitoring and preventing phototoxicity caused by VVD illumination during ophthalmic surgery. The method may further include determining the distance between a cutter of the VVD and the retina, and determining areas where the vitreous has been removed based on focus areas of the retina that the plurality of light spots has contacted.

    Abstract: In certain embodiments, a system for sensing occlusions in an optical system includes a first laser source configured to generate optical signals and a set of optical elements arranged to receive the optical signals from the first laser source and to direct the optical signals along a beam path. The system also includes a detector arranged to receive reflections of the optical signals travelling along at least a portion of the beam path and a control system communicably coupled to the detector. The control system is configured to detect, based on signals generated by the detector, reflection signals associated with the reflections of the optical signals, and disable a second laser source based on detection of the reflection signals.
