Abstract
This invention is a system, an apparatus and a method for measuring biomechanical properties of cornea and the intraocular pressure in vivo. More than one dimensional topographic information of the cornea is recorded and analyzed before and during the fluid discharge and converted to the stress-strain relationship and other cornea parameters, for example the cornea thickness and radius of curvature, etc. The deformation of cornea is initiated by a non-contact fluid discharge whose profile is predetermined and monitored in real time. Utilizing this non-contact topographer, the true intraocular pressure can be derived from the response of the cornea due to the impact of fluid discharge and the corneal topographic parameters. One embodiment of this invention includes the use of a multiple color strobe light/multiple detector system to record the corneal topographic deformation due to the impact of fluid discharge.
