Abstract:
A trans-scleral method of measuring intraocular pressure comprising the steps ofproviding a tonometer having a distal tip, said distal tip includes a transducer, contacting the distal tip of the tonometer to the surface of the sclera of the eye being measured, aligning the tonometer along an axis such that the transducer can be tangent to the scleral surface of the eye being measured, creating an electrical waveform produced by contacting the transducer in the distal tip of the tonometer to the surface of the sclera of the eye being measured, converting the electrical waveform to a digital signal, processing the digital signal to calculate intraocular pressure, compensating for normal sclera tissue-specific properties, and calculating the intraocular pressure of the eye being measured.
