Pascal Tonometer: Dynamic Contour Tonometry
2013The Pascal tonometer is for measuring IOP and uses a method called contour tonometry. Its main feature for us is that it measures IOP without this being affected by the thickness of the cornea. It has a printer that prints out not only the IOP values but also the quality of the measurement as well as the short-term IOP fluctuations (Fig. 12.1) when the

To compare the measurements of intraocular pressure (IOP) with dynamic contour tonometry (DCT) and Goldmann applanation tonometry (GAT) in eyes with corneal graft and to evaluate the influence of corneal thickness (CCT), corneal curvature (CC), and astigmatism on these methods.Prospective, observational cross-sectional study.Eighteen eyes of 18 ...

Dynamic Contour Tonometry: Handheld versus Slit-lamp–Mounted
Ophthalmology, 2009PURPOSE: To compare the newly developed handheld dynamic contour tonometer (hh-DCT) with the established slit-lamp-mounted DCT (sl-DCT) in terms of agreement for intraocular pressure (IOP) and ocular pulse amplitude (OPA) measurements, intraobserver variability, and tonography effect. DESIGN: Evaluation of diagnostic technology.

[Evaluation of dynamic contour tonometry in keratoconus].
Der Ophthalmologe : Zeitschrift der Deutschen Ophthalmologischen Gesellschaft, 2009The gold standard for measuring intraocular pressure (IOP) until now has been Goldmann applanation tonometry (GAT), which depends on the central corneal thickness (CCT) and curvature. In patients with keratoconus who have an abnormal corneal geometry and thickness, measurement of pressure with GAT is often difficult and not very reproducible.

Accurate determination of intraocular pressure (IOP) is essential for correct management of glaucoma. Goldmann applanation tonometry (GAT) is the gold standard for measuring IOP despite its limitations due to its dependence on corneal properties. With the aim of improving the accuracy of GAT readings, several correction formulas have been developed.The

[Evaluation of dynamic contour tonometry in penetrating keratoplasties].
Der Ophthalmologe : Zeitschrift der Deutschen Ophthalmologischen Gesellschaft, 2006The PASCAL dynamic contour tonometer (DCT) adapted to the corneal geometry is a new approach for digital measurement of intraocular pressure (IOP). The purpose of this study was to evaluate the DCT vs Goldmann applanation tonometry (GAT) in penetrating keratoplasties.We included 92 consecutive eyes after penetrating keratoplasty (57 without sutures, 32
