ABSTRACT:
The invention provides a hypoallergenic disposable cover for the probe tip of a contact tonometer comprising a thin film having an ultimate elongation in the range of 500 to 1000%, a tensile strength in the range of 1000 to 5500 psi and a modulus of elasticity at 100% strain in the range of 50 to 2000 psi, whereby when installed onto the probe tip, the cover creates a barrier against microorganisms from the eye of a patient to said probe tip during a tonometric examination while allowing measurement of intraocular pressure through the disposable tip cover.
