PURPOSE We evaluated various preoperative anterior segment parameters measured with a Pentacam rotating Scheimpflug camera and compared them with those of conventional methods. We also evaluated the effect of different parameters on corneal endothelial cells after cataract surgery. METHODS Pentacam examination was performed in 88 eyes from 88 patients to evaluate central anterior chamber dept...

PURPOSE To assess the intraoperator repeatability and interoperator reproducibility of central corneal thickness measurements by the Pentacam Scheimpflug imaging system (Oculus) and the optical low-coherence reflectometer (OLCR) pachymeter (Haag-Streit) and to compare them with those of ultrasound (US) pachymetry. SETTING Assaf Harofe Medical Center Ophthalmology Outpatient Clinic, Zerifin, I...

PURPOSE To compare the anterior segment indices measured by two Scheimpflug camera machines; Galilei and Pentacam. METHODS In this observational case series, the anterior segment indices of myopic healthy subjects seeking for refractive surgery were measured by Pentacam and Galilei on the same day. Analyzed parameters were anterior and posterior best fit spheres (BFS), axial curvature, true c...

PURPOSE To determine inter-device agreement for central corneal thickness (CCT) measurement among ultrasound pachymetry, rotating Scheimpflug imaging (Pentacam, Oculus, Wetzlar, Germany), and scanning slit corneal topography (Orbscan II, Bausch & Lomb, Rochester, NY, USA) in highly myopic eyes before and after photorefractive keratectomy (PRK). METHODS This prospective comparative study inclu...

PURPOSE To compare three different methods of measuring corneal thickness (CT) and anterior chamber depth (ACD). DESIGN Prospective clinical trial (Medical University of Vienna, Austria). METHODS Central CT (CCT), CT at four peripheral points, and central ACD were measured in 88 eyes of 44 healthy subjects with the Pentacam (rotating Scheimpflug camera; Oculus, Wetzlar, Germany), Orbscan I ...

Purpose: To compare Orbscan II and Pentacam keratometry readings in terms of their agreement with a manual Javal type keratometer Methods: In this retrospective study, records of patients who had refractive surgery were reviewed. We extracted data of 765 eyes which had keratometry with the Javal keratometer; of these, 577 had Orbscan II and 200 eyes had Pentacam acquisitions. Minimum (min-K) an...

PURPOSE To compare the changes in posterior corneal curvature using scanning slit topography (Orbscan II) and Scheimpflug imaging (Pentacam) before and after Epi-laser in situ keratomileusis (LASIK) for myopia. METHODS In a prospective observational case-series study, 20 myopic patients having undergone Epi-LASIK were examined serially with two different devices, Orbscan II and Pentacam, preo...

INTRODUCTION Anterior and posterior corneal elevations are measurements used to detect keratoconus suspects. PURPOSE To determine the efficacy of Orbscan II and Pentacam when assessing their elevation maps. MATERIALS AND METHODS The efficacy of the Orbscan II and Pentacam measuring the anterior and posterior corneal elevations were evaluated in a sample of 68 eyes. The concordance between t...

PURPOSE To compare central corneal thickness (CCT) measurements obtained using the Pentacam Scheimpflug system with those obtained using DGH ultrasound pachymetry (UP) in post-laser in situ keratomileusis (LASIK) eyes for myopia. METHODS In a prospective study, measurement agreement was assessed in 143 eyes of 72 post-LASIK patients using both the Pentacam and UP at the Eye Consultants Center...

PURPOSE The aim of this study was to compare 4 methods of central corneal thickness (CCT) measurements in terms of their agreement, repeatability, and measurement time. METHODS CCT was measured in 184 eyes of 92 healthy subjects by the same examiner. The methods used were as follows: noncontact specular microscopy (SM; Topcon SP-3000P; Topcon Corporation, Tokyo, Japan), Pentacam rotating Sche...
