  • Publication number: 20220331508
    Abstract: A surgical cassette for an ophthalmic surgical system includes an irrigation system and an aspiration system. The irrigation system is in fluid communication with a handpiece and carries fluid toward a surgical site. The aspiration system is in fluid communication with the handpiece and carries fluid away from the surgical site. The aspiration system includes an aspiration pump and tubing of an aspiration conduit. The aspiration pump generates a normal vacuum pressure within the aspiration conduit to carry fluid away from the surgical site during normal operation. The tubing has a larger cross-sectional area in response to normal vacuum pressure. The tubing collapses from the larger cross-sectional area to a smaller cross-sectional area in response to an occlusion; maintains the smaller cross-sectional area during a post-occlusion break surge to mitigate the post-occlusion break surge; and returns to the larger cross-sectional area after the post-occlusion break surge.
