Continuous aspiration serves to prevent the accumulation of fluids in the internal canthal area during the course of intraocular surgery. The prevention of this fluid accumulation is necessary in order to prevent the flow of irrigating fluids directed onto the eye from accumulating in the internal canthal area to such an extent that fluid bathing the skin can possibly re-enter an opened eye. This is always a possible avenue for infection because of the likely presence of contaminating skin bacteria. Excessive fluid accumulation also serves to obscure visualization of fine tissue details in some instances. In the course of surgery, transient copious irrigation is desirable insomuch as it permits point cauterization of incisional bleeders which are more readily visualized in the presence of an irrigating stream. The Scheie cautery has proved most effective for point cauterization in the presence of liquids because it is possible to regulate the current and
