Analysis of Four Aberrometers for Evaluating Lower and Higher Order Aberrations
PURPOSE To compare the measurements of lower and higher order aberrations (HOA) of 4 commonly used aberrometers. SETTING Massachusetts Eye & Ear Infirmary, Boston, USA. DESIGN Prospective, cross-sectional study, in a controlled, single-blinded fashion. METHODS Multiple readings were obtained in 42 eyes of 21 healthy volunteers, at a single visit, with each of the following aberrometers: A...
متن کاملPrecision and agreement of higher order aberrations measured with ray tracing and Hartmann-Shack aberrometers
BACKGROUND To assess the precision and agreement of measurements of higher order aberrations (HOAs) obtained with a ray tracing aberrometer (iTrace) and a Hartmann-Shack aberrometer (Topcon KR-1 W). METHODS Prospective evaluation of the diagnostic test. Data from the right eyes of 92 normal subjects obtained using the two devices were included in this study. Two observers performed 3 consecut...
متن کاملEvaluation of the comparability and repeatability of four wavefront aberrometers.
PURPOSE To compare total ocular aberrations and corneal aberrations identified with four different aberrometers and to determine the repeatability and interobserver variability. METHODS In this prospective comparative study, 23 healthy subjects underwent bilateral examination with four aberrometers: the Irx3 (Hartmann-Shack; Imagine Eyes, Orsay, France), Keratron (Hartmann-Shack; Optikon, Rom...
متن کاملWavefront-Guided LASIK and Preoperative Higher Order Aberrations.
We read with interest the article by Kung and Manche in the April 2016 issue.1 In the first part of the article, they explained that most studies seemed to suggest that the wavefront-guided excimer laser procedures were slightly superior than wavefront-optimized approaches, particularly in patients with preoperative root mean square (RMS) of higher order aberrations (HOAs) less than 0.3 μm. How...
متن کاملComparison of Higher Order Aberrations after Wavefront-guided LASIK and PRK: One Year Follow-Up Results
PURPOSE To evaluate the changes and predictability of higher order aberrations (HOAs) after personalized laser in situ keratomileusis (LASIK) and personalized photorefractive keratectomy (PRK) for simple myopia and compound myopic astigmatism. METHODS In this prospective cross-sectional study, 100 eyes were included. A total of 50 eyes underwent personalized LASIK and 50 eyes underwent person...
