Measurement of Central Corneal Thickness Using Ultrasound Pachymetry and Orbscan II in Normal Eyes
PURPOSE To compare ultrasound pachymetry and Orbscan II for measurement of central corneal thickness (CCT) in normal eyes. METHODS The current study was performed at Labbafinejad Medical Center (LMC), Tehran, Iran. Three hundred eyes from 150 healthy individuals referred for keratorefractive surgery were assessed first by Orbscan II and then by ultrasound pachymetry, and CCT values were recor...
متن کاملCentral and peripheral corneal thickness measurement with Orbscan II and topographical ultrasound pachymetry.
PURPOSE To compare thickness measurements of the central 6.0 mm of the cornea obtained with the Orbscan(R) II topography system and topographical ultrasound pachymetry. SETTING School of Optometry, University of Santiago de Compostela, Galicia, Spain. METHODS In 24 right eyes, pachymetric measurements were taken at the center and 1.2 mm and 3.0 mm on the superior and inferior hemimeridians....

purpose: to compare orbscan ii (o ii) and ultrasound (us) pachymetry in normal and post-lasik eyes. methods: in a comparative prospective study, central corneal thickness (cct) was measured in 168 eyes of 84 normal subjects and 42 eyes without corneal opacity of 21 post-lasik patients by o ii and us. paired t test was used to identify significant differences between the two methods and pearson ...
متن کاملCentral Corneal Thickness Measurement by Ultrasound versus Orbscan II
PURPOSE To compare Orbscan II and ultrasonic pachymetry for measurement of central corneal thickness (CCT) in eyes scheduled for keratorefractive surgery. METHODS CCT was measured using Orbscan II (Bausch & Lomb, USA) and then by ultrasonic pachymetry (Tomey SP-3000, Tomey Ltd, Japan) in 100 eyes of 100 patients with no history of ocular surgery scheduled for excimer laser refractive surgery....
متن کاملComparison of Central Corneal Thickness Measurement Using Non-Contact and Contact Pachymetry Devices in Normal Eyes
Materials and Methods: This prospective, cross sectional comparative study evaluated 30 healthy subjects fulfilling the inclusion criteria reporting in AFIO Rawalpindi. CCT was measured in both eyes of subjects using noncontact specular microscope, Dual Scheimpflug analyzer and contact ultrasound pachymeter by a single investigator at the same time of the day. Pearson’s correlation coefficient ...
