Repeatability of Pentacam peripheral corneal thickness measurements
Contact Lens and Anterior Eye, 2015To assess the repeatability of corneal thickness (CT) measurements, along the horizontal meridian up to 5mm from centre, in healthy eyes with the Pentacam instrument.CT was measured in 82 right eyes (82 healthy subjects) at 11 corneal locations nominally 1mm apart along the horizontal meridian with Scheimpflug topography Pentacam. Two consecutive scans

Pentacam measurements and IOL scattering
Acta Ophthalmologica, 2013AbstractRigid and foldable intraocular lenses of various materials have shown light scattering phenomena such as surface light scattering and glistenings. The impact of these phenomena on visual function is under controversial discussion. The scattering of light in an IOL can be measured in various ways.

Heritability of pachymetric indices using Pentacam Scheimflug imaging
British Journal of Ophthalmology, 2019AimTo investigate the heritability of corneal thickness at the apex, entrance pupil centre, thinnest point, pachymetric progression index (PPI) and maximum Ambrósio relational thickness (ARTmax) using Pentacam.MethodsThe present cross-sectional and population-based study was conducted in two rural districts that were selected randomly.

Agreement Between Pentacam and Videokeratography in Corneal Power Assessment
Journal of Refractive Surgery, 2009Purpose: To investigate agreement between a rotating Scheimpflug camera (Pentacam, Oculus Optikgeräte GmbH) and two corneal topographers (TMS-2 Topography System, Tomey; and Keratron Scout, Optikon 2000 SpA) in measuring the corneal power of normal eyes.

Variability in Oculus Pentacam Tomographer Measurements in Patients With Keratoconus
Cornea, 2015The aim of this study was to determine intertest variability of measurements taken by the Pentacam tomographer in eyes with keratoconus.Three Pentacam measurements with 1-minute intervals were taken from 101 eyes (81 keratoconus and 20 controls) from 57 patients (47 keratoconus and 10 controls) by the same examiner and under the same conditions ...
