The present disclosure provides a vitreous visualization system including a general light source, a general conduit that transmits light from the general light source through a conduit portion of a general illumination optical fiber, and a combined vitreous visualization and general illumination tool that receives light from the general conduit. The combined vitreous visualization tool includes a vitreous visualization light source, a controller for the vitreous visualization light source, a vitreous visualization optical fiber, a tool portion of the general illumination optical fiber, and a probe tip through which at least parts of both the vitreous visualization optical fiber and the tool portion of the general illumination optical fiber pass.

Systems and methods using a vitreous visualization tool

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.
