Volume changes in indentation tonometry.

Why Indentation Cannot Be Considered Exactly Equivalent to Non-contact Tonometry.

Why Indentation Cannot Be Considered Exactly Equivalent to Non-contact Tonometry We read the article by Ortillés et al. in the March 2017 issue that compared the indentation method with uniaxial extensiometry results in rabbit eyes with great interest.1 Unfortunately, we observed that the analyses of the results did not match the conclusions. Further, the experimental methods were incomplete an...

Tonometry in corneal edema after cataract surgery: dynamic contour tonometry versus Goldmann applanation tonometry

INTRODUCTION Intraocular pressure (IOP) determination using dynamic contour tonometry (DCT) has been considered to be independent of central corneal thickness (CCT), while Goldmann applanation tonometry (GAT) is known to be influenced by various corneal properties. In this study, IOP was measured before and 1 day after cataract surgery using GAT and DCT to investigate the possible effects of co...

Evaluation of Goldmann applanation tonometry, rebound tonometry and dynamic contour tonometry in keratoconus

PURPOSE To compare the intraocular pressure (IOP) measurements obtained with the rebound tonometry (RT), dynamic contour tonometry (DCT) and Goldmann applanation tonometry (GAT) in keratoconic corneas and to investigate the effects of central corneal thickness (CCT) and corneal radius of curvature (CR) on IOP measurements. METHODS Sixty-three eyes of 63 keratoconus patients were enrolled in t...

[Rebound tonometry in a clinical setting. Comparison with applanation tonometry].

PURPOSE Rebound tonometry has recently been modified for its use in humans. The purpose of our study was to determine the precision of the ICare(R) rebound tonometer (RBT) as compared with the Goldmann applanation tonometer (GAT). METHODS Patients were recruited from our Hospital's Glaucoma Unit. In each patient, intraocular pressure (IOP) was measured without anaesthesia using the RBT and te...
