摘要

This article describes a study based on the use of an instrumented form of applanation and indentation tonometry through eyelid.The methods and devices which are available for the measurement of intraocular pressure(IOP)have their own limitations.These cause discomfort to the patients during IOP measurement.Also these methods,used to measure IOP over cornea,need anesthesia.In the present work,an attempt is made to develop a device for the measurement of IOP through eyelid which eliminates the need of anesthesia and enhance the patient’s comfort and convenience of the clinician.To represent the results of proposed technique,the human eye modeled with cornea,sclera and also with the eyelid,is used.Furthermore,simulation results of stress values for the range of IOP i.e.5-40 mm of Hg are presented and discussed comparatively with eyelid and without eyelid i.e.directly‘on cornea’methods.
