Abstract
A sterile disposable frustoconically-shaped plastic cover or cap adapted to fit over and be releasably and frictionally secured to the corresponding surfaces of a tonometer tip, having a planar lens portion at its smaller circumference adapted to lie against both the lens of the tonometer tip and against the cornea of the eye of a patient being examined with the tonometer, the lens portion of the cover being of optical clarity so as not to interfere with readings obtained with the tonometer, is disclosed. The cap includes peripheral slits for frictional and releasable securement of the cover about the surfaces of various-sized tonometer tips and external flanges for gripping the cover without contact with its lens portion, and is preferably constructed as a unitary device from a single plastic of optical clarity and packaged in the well of special packaging in which it is sterlized.
