Goldmann Tonometer Prism with an Optimized Error Correcting Applanation Surface
PURPOSE We evaluate solutions for an applanating surface modification to the Goldmann tonometer prism, which substantially negates the errors due to patient variability in biomechanics. METHODS A modified Goldmann or correcting applanation tonometry surface (CATS) prism is presented which was optimized to minimize the intraocular pressure (IOP) error due to corneal thickness, stiffness, curva...
متن کاملGoldmann tonometer error correcting prism: clinical evaluation
PURPOSE Clinically evaluate a modified applanating surface Goldmann tonometer prism designed to substantially negate errors due to patient variability in biomechanics. METHODS A modified Goldmann prism with a correcting applanation tonometry surface (CATS) was mathematically optimized to minimize the intraocular pressure (IOP) measurement error due to patient variability in corneal thickness,...
متن کاملComparative evaluation of intraocular pressure with an air-puff tonometer versus a Goldmann applanation tonometer
PURPOSE Tonometry, or measurement of intraocular pressure (IOP), is one of the most important examination procedures in ophthalmic clinics, and IOP is an important parameter in the diagnosis of glaucoma. Because there are numerous types of tonometer available, it is important to evaluate the differences in readings between different tonometers. Goldmann applanation tonometers (GATs) and noncont...
متن کاملComparison of IOPen rebound tonometer with Goldmann applanation tonometer at different IOP levels.
AIM To compare the accuracy of IOPen rebound tonometer with Goldmann applanation tonometer (GAT) in individuals with low, normal and high intraocular pressure (IOP) and to evaluate the effect of central corneal thickness (CCT) on IOP measurements. METHODS This cross-sectional study consisted of 159 participants. IOP of one eye of each subject was measured consecutively with IOPen and GAT. The...
متن کاملComparison 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,...
