Repeatability of layered corneal pachymetry with the artemis very high-frequency digital ultrasound arc-scanner.
PURPOSE To assess the three-dimensional repeatability of thickness measurements for epithelium, stroma, cornea, flap, and residual stromal bed using the Artemis very high-frequency (VHF) digital ultrasound arc-scanner (ArcScan Inc). METHODS Five consecutive measurements were obtained for 10 eyes of 10 patients 1 year after LASIK using the Artemis VHF digital ultrasound arc-scanner across the ...
متن کاملAnterior segment biometry using ultrasound biomicroscopy and the Artemis-2 very high frequency ultrasound scanner
PURPOSE To compare the precision of anterior chamber angle (ACA) and anterior chamber depth (ACD) measurements taken with ultrasound biomicroscopy (UBM) and the Artemis-2 Very High Frequency Ultrasound Scanner (VHFUS) in normal subjects. DESIGN Prospective study. METHODS We randomly selected one eye from each of 59 normal subjects in this study. Two subjects dropped out of the study; the as...
متن کاملRepeatability and interobserver reproducibility of Artemis-2 high-frequency ultrasound in determination of human corneal thickness
BACKGROUND The purpose of this study was to assess the repeatability and limits of agreement of corneal thickness values measured by a high-frequency ultrasound (Artemis-2), hand-held ultrasound pachymeter (DGH-500) and a specular microscope (SP-3000P). METHODS Central corneal thickness (CCT) was analyzed in this prospective randomized study that included 32 patients (18 men and 14 women) age...
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 کاملArtemis very high frequency digital ultrasound-guided femtosecond laser recut after flap complication.
Incomplete flaps are a relatively uncommon complication of laser-assisted in situ keratomileusis (LASIK) that occur when creation of the corneal flap is interrupted. Further complications can arise if a second flap is created that intersects the original flap interface, resulting in tissue slivers that can lead to more complications and poor visual outcomes. We report the case of a 56-year-old ...
