Comparison of ICare, dynamic contour tonometer, and ocular response analyzer with Goldmann applanation tonometer in glaucoma
Purpose. To compare the intraocular pressure (IOP) readings taken by ICare, Pascal dynamic contour tonometer (DCT), and ocular response analyzer (ORA) with those taken by Goldmann applanation tonometer (GAT). We sought to evaluate the influence of central corneal thickness (CCT) on IOP measurements and to compare patients’ preferences for the four tonometers. Methods. In this prospective study,...
متن کاملintraocular pressure measurements after penetrating keratoplasty using the ocular response analyzer versus goldmann applanation tonometer
purpose: to compare intraocular pressure (iop) readings measured by the ocular response analyzer (ora) with those measured by the goldmann applanation tonometer (gat) in keratoconic eyes following penetrating keratoplasty (pkp) and to evaluate the influence of anatomical and biomechanical properties of the grafts on iop measurements. methods: this cross-sectional study was conducted on 45 kerat...
متن کاملOcular Response Analyzer
Until recently, corneal biomechanical properties could not be measured in vivo. The ocular response analyzer is a new, noninvasive device that analyses corneal biomechanical properties simply and rapidly. The ORA allows cornea compensated IOP measurements and can estimate corneal hysteresis (CH) and corneal resistance factor (CRF). It is designed to improve the accuracy of IOP measurement by us...

متن کاملComparison of the ocular response analyzer and the Goldmann applanation tonometer for measuring intraocular pressure after deep anterior lamellar keratoplasty.
PURPOSE To compare intraocular pressure (IOP) measured using the Ocular Response Analyzer (ORA; Reichert Ophthalmic Instruments, Buffalo, NY) with that measured using the Goldmann applanation tonometer (GAT) in keratoconic eyes after deep anterior lamellar keratoplasty (DALK) and evaluate the influence of central graft thickness (CGT), corneal astigmatism, corneal hysteresis (CH), and corneal r...
