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....
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 Measured through Pentacam, OCTCasia2, and Orbscan IIz in Normal Individuals
Purpose: To compare the central corneal thickness measured through Pentacam, OCTCasia2, and Orbscan IIz in normal individuals. Methods: In this cross sectional comparative study, the researcher investigated the eyes of 70 normal candidates (140 eyes) with the mean age of 31.42 ± 7.70, referring to Dr. Sedaghat eye clinic for refractive surgery. For each person, Central Corneal Thickness (CCT) w...
متن کاملComparison of central corneal thickness: ultrasound pachymetry versus slit-lamp optical coherence tomography, specular microscopy, and Orbscan
BACKGROUND Central corneal thickness (CCT) can be measured by using contact and non-contact methods. Ultrasound pachymetry (US pachymetry) is a contact method for measuring CCT and is perhaps the most commonly used method. However, non-contact methods like scanning slit topography (Orbscan II), slit-lamp optical coherence tomography (SL-OCT), and specular microscopy are also used. Not many stud...
