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 measurements using ultrasound pachymetry, ultrasound biomicroscopy, and the Artemis-2 VHF scanner in normal eyes
PURPOSE To compare the precision of central corneal thickness (CCT) measurements taken with the handheld ultrasound pachymeter (USP), ultrasound biomicroscopy (UBM), and the Artemis-2 very high frequency ultrasound scanner (VHFUS) on normal subjects. DESIGN Prospective study. METHODS One eye from each of 61 normal subjects was randomly selected for this study. The measurements of the CCT we...
متن کاملCorneal Thickness in Pigs Measured by Ultrasound Pachymetry In Vivo
Corneal transplantation is the most frequently performed type of tissue grafting (George & Larkin, 2004). It is a highly successful treatment of severe corneal disease. However, transplantation of tissue and organs in humans has a major setback: availability of donors. To solve this, there are currently many studies on the possible use of the pig as a source of hearts, kidneys, livers, Islets o...
