Abstract:
A method of measuring intra-ocular pressure of an eye comprising the steps of:(A) directing a fluid pulse at a cornea to cause reversible deformation of said cornea from an original state of convexity through a first state of applanation to a state of concavity, and back through a second state of applanation to said state of convexity; (B) monitoring said corneal deformation as a function of time to generate a signal indicating a time of said first state of applanation and a time of said second state of applanation; (C) measuring a first plenum pressure corresponding to said time of said first state of applanation and a second plenum pressure corresponding to said time of said second state of applanation; (D) inputting said first and second plenum pressures to respective first and second regression equations to provide respective first and second intra-ocular pressure values; and (E) calculating a final intra-ocular pressure value based on said first and second intra-ocular pressure values.
