The effect of corneal thickness and corneal curvature on pneumatonometer measurements
Current Eye Research, 2002The purpose of this study was to investigate the influence of corneal topography and thickness on intraocular pressure (IOP) and pulse amplitude (PA) as measured using the Ocular Blood Flow Analyzer (OBFA) pneumatonometer (Paradigm Medical Industries, Utah, USA).47 university students volunteered for this cross-sectional study: mean age 20.4 yrs, range

Corneal curvature and central corneal thickness in eyes with pseudoexfoliation syndrome
Canadian Journal of Ophthalmology, 2007Previous studies have reported different central corneal thickness (CCT) values in eyes with pseudoexfoliation syndrome (PXS). There has been no report about corneal curvature (CC) in PXS eyes. The aim of this study was to investigate the CCT together with the CC in PXS eyes with and without glaucoma.The CC (simulated keratometry 1 [SimK1], SimK2, and ...

CORNEAL CURVATURE EROM PROFILE MEASUREMENTS*
The Australian Journal of Optometry, 1971The determination of corneal curvature from profile photographs has received scant attention in the past history of research into corneal topography. This paper describes the principal elements of experimental procedures involved in profile measurements and summarizes some experimental work being undertaken to eliminate the validity and potential of ...

Local Steepening in Peripheral Corneal Curvature After Corneal Refractive Therapy and LASIK
Optometry and Vision Science, 2010The purpose of this study was to assess the changes in curvature along the horizontal meridian of the anterior cornea occurring after refractive surgery and corneal refractive therapy (CRT).One hundred twenty-two eyes of 122 patients (70 female) with a mean (SD) age of 30.6 +/- 7.5 years were retrospectively analyzed in this study. Forty-three of those

CORNEAL CURVATURE CHANGES USING HYDROPHILIC LENSES
The Australian Journal of Optometry, 1971Corneal curvature changes of nineteen eyes using Hydron* hydrophilic lenses are reported. Half the eyes had some significant curvature change in at least one meridian, but only six eyes had a corneal astigmatism change over 0.25 D. It was concluded that, if any change were to take place in corneal curvatures, it would more likely be a flattening of the
