متن کاملAccuracy of optical biometry combined with Placido disc corneal topography for intraocular lens power calculation
PURPOSE To investigate the accuracy of a new optical biometer for intraocular lens (IOL) power calculation in eyes undergoing cataract surgery. METHODS Consecutive eyes of patients undergoing cataract surgery with the same IOL model were enrolled in a prospective cohort study. Axial length (AL) and corneal power were measured with an optical biometer based on optical low-coherence interferome...
متن کاملagreement among galilei, orbscan ii, and placido disk-based topography
purpose: to evaluate agreement between galilei, orbscan ii, and placido disk-based topography in terms of keratometry readings, and anterior and posterior elevation. methods: in this prospective comparative study, 184 eyes of 92 keratorefractive surgery candidates were evaluated with galilei, orbscan ii, and placido disk-based topography. keratometry readings and anterior and posterior elevatio...
متن کاملEvaluation of corneal thickness and topography in normal eyes using the Orbscan corneal topography system.
AIMS To map the thickness, elevation (anterior and posterior corneal surface), and axial curvature of the cornea in normal eyes with the Orbscan corneal topography system. METHODS 94 eyes of 51 normal subjects were investigated using the Orbscan corneal topography system. The anterior and posterior corneal elevation maps were classified into regular ridge, irregular ridge, incomplete ridge, i...
متن کاملCalculation of intraocular lens power using Orbscan II quantitative area topography after corneal refractive surgery.
PURPOSE To present the prospective application of the Orbscan II central 2-mm total-mean corneal power obtained by quantitative area topography in intraocular lens (IOL) calculation after refractive surgery. METHODS Calculated and achieved refraction and the difference between them were studied in 77 eyes of 61 patients with previous radial keratotomy (RK), RK and additional surgeries, myopic...
