A I-tonometer idla ngokuqulunqwa kwi-corneal shape change generator, inkqubo yokulinganisa i-corneal deformation okanye i-contact corneal device kunye ne-sensor yokutshintsha uxinzelelo.Isetyenziselwa ukulinganisa uxinzelelo lwe-intraocular.Iimveliso eziqhelekileyo zi i-tonometer, i-non-contact tonometer, i-tonometer ephathwa ngesandla, i-applanation tonometer ephathwa ngesandla, i-applanation tonometer, i-piezoelectric tonometer yoqhagamshelwano, i-rebound tonometer, i-Indentation tonometer, njl.. Inokunceda ekuxilongweni kwe-cataract, i-glaucoma kunye nezinye izifo zamehlo.I-tonometer engabonakaliyo isetyenziswa ngokuqhelekileyo ngoku, enenzuzo yokusebenza okulula kunye nokulinganisa ngokukhawuleza.
