Abstract

To the Editor:  —My attention has been called to a communication in The Journal, Dec. 3, 1932, from Dr. Walter B. Lancaster commenting on an eye speculum for cataract extraction which I described and illustrated in The Journal. Oct. 8, 1932, page 1252.Dr. Lancaster says that the eye speculum is a good illustration of how far one can go afield if one starts from an erroneous premise.I started from the premise that a patient with a cataract incision and an unsupported speculum in the eye can expel vitreous by a contraction of the orbicularis muscle. If that premise is erroneous, I have indeed gone far afield.I agree fully with Dr. Lancaster when he says, "Expulsion of vitreous during cataract operations may come from either or both of two causes: pressure on the eyeball by the surgeon, or pressure on the eyeball by the patient through muscular action."
