Evaluation of posterior astigmatism measured with Scheimpflug imaging.
PURPOSE Our aim was to assess the corneal power, axis, and age dependence of the anterior and posterior corneal surfaces with Scheimpflug imaging. METHODS Patients older than 10 years without a history of ocular surgery, corneal diseases, contact lens wearing, or severe dry eye were enrolled. Data regarding the anterior and posterior cornea were analyzed by means of Scheimpflug imaging (Penta...
متن کاملRepeatability and validity of lens densitometry measured with Scheimpflug imaging.
PURPOSE To assess the repeatability and validity of lens densitometry derived from the Pentacam Scheimpflug imaging system. SETTING Eye Clinic, Queensland University of Technology, Brisbane, Australia. METHODS This prospective cross-sectional study evaluated 1 eye of subjects with or without cataract. Scheimpflug measurements and slitlamp and retroillumination photographs were taken through...
متن کاملHigh heritability of posterior corneal tomography, as measured by Scheimpflug imaging, in a twin study.
PURPOSE Anterior corneal curvature shows significant heritability. Scheimpflug imaging also permits assessment of posterior tomography. We estimated heritability of posterior and anterior tomographic parameters. METHODS Oculus Pentacam images were obtained in twins from the TwinsUK cohort. Mean anterior and posterior radii of curvature (right cornea) were compared within twin pairs, and herit...
متن کاملP 239 Relationship between implanted posterior chamber lens and posterior capsule — Measured by scheimpflug photography
m Implantation of posterior ch.unber lenses (intmcalar lens = IOL) is an established method to replace opaque lenses. Prefered positioning of implanted lenses is in the capsular bag. either with or without touching the posterior capsule. Purpose of the present study is to determine the real position of the implanted lens in relation to the posterior capsule and to measure a possible distance be...
