The Pascal® dynamic contour tonometer (DCT) was designed to measure IOP independently of corneal properties.
To compare dynamic contour tonometry as a new method for intraocular pressure measurement with Goldmann applanation tonometry.
The closed-form results for the dynamic field intensity factors are used to evaluate the dynamic energy release rate through the crack-tip dynamic contour integral.
To identify correlations among intraocular pressure (IOP) measurements obtained using the rebound tonometer (RBT), the dynamic contour tonometer (DCT), and the Goldmann applanation tonometer (GAT).
The difference between the global and local dynamic contour integrals is caused by unsteady state, mechanical body force, electricity conduction and thermal effect as the closed contour including crack faces is chosen.
For image segmentation, the level set function can be formulated as ϕ x,y,t), on the image coordinate space [x,y]∈Ω and time direction, which embeds the dynamic contour at the zero level set.
To examine the repeatability and reproducibility of intraocular pressure (IOP) measurements obtained with the Goldmann applanation tonometer (GAT), the Pascal dynamic contour tonometer (DCT; Swiss Microtechnology AG, Port, Switzerland), and the Reichert Ocular Response Analyzer (ORA; Reichert Ophthalmic Instruments, Buffalo, NY).
To compare intraocular pressure (IOP) measurements using a new tonometer pachymeter device (Tonopachy), Goldmann applanation tonometry (GAT), dynamic contour tonometry (DCT), and noncontact tonometry (NCT) before and after myopic laser-assisted subepithelial keratectomy (LASEK).
To compare the measurements of intraocular pressure (IOP) with Goldmann applanation tonometry (GAT) and dynamic contour tonometry (DCT) and the effects of central corneal thickness (CCT), corneal curvature, and level of IOP on these methods.
