Evaluation of Equivalent Keratometry Readings Obtained by Pentacam HR (High Resolution)

Evaluation of Equivalent Keratometry Readings Obtained by Pentacam HR (High Resolution)

PURPOSE To assess the repeatability of Equivalent Keratometry Readings (EKRs) obtained by the Pentacam HR (high resolution) in untreated and post-LASIK eyes, and to compare them with the keratometry (K) values obtained by other algorithms. METHODS In this prospective study, 100 untreated eyes and 71 post-LASIK eyes were included. In the untreated group, each eye received 3 consecutive scans u...

Accuracy of Scheimpflug Holladay equivalent keratometry readings after corneal refractive surgery.

PURPOSE To determine the accuracy of Pentacam Scheimpflug system Holladay equivalent keratometry (K) readings (EKRs) in calculating intraocular lens (IOL) power after corneal refractive surgery, including laser in situ keratomileusis (LASIK), photorefractive keratectomy (PRK), and radial keratotomy (RK). SETTING Jules Stein Eye Institute, David Geffen School of Medicine at University of Calif...

Repeatability and Agreement of Central Corneal Thickness and Keratometry Measurements between Four Different Devices

Background. To estimate repeatability and comparability of central corneal thickness (CCT) and keratometry measurements obtained by four different devices in healthy eyes. Methods. Fifty-five healthy eyes from 55 volunteers were enrolled in this study. CCT (IOLMaster 700, Pentacam HR, and Cirrus HD-OCT) and keratometry readings (IOLMaster 700, Pentacam HR, and iDesign) were measured. For statis...

High Resolution Diffusion-Ordered Spectroscopy (HR-DOSY)

This application note demonstrates the utility of the DOSY package in the VnmrJ 3.1 software for both 2D and 3D HR-DOSY analysis of complex mixtures, by first elucidating the presence of two components in an epoxy mixture (2D), and then proving that a minority component in a protein mixture was in fact a smaller derivative of the major component (3D).
