A cassettefor use with an ophthalmic surgical pumpfor collecting aspirant fluid and tissue from a patient's eye includes a rigid walled containerhaving an interior volume. At least one tapered alignment slotis formed in a side wall of the containerand extends from a back walltowards a front wall. An irrigation and aspiration manifold baseis removeably attached to the container. An aspiration pathis formed within the containerfor receiving the aspiration fluid and the tissue from the eye and directing the flow of fluid towards a front half of the containerbefore the fluid and tissue collects within a majority of the interior volumeof the container. A fluid level indicatoris formed on a wallof the container, such that an associated photo-detectorof the pumpmay determine a level of fluid in the container
