      Longitudinal Evaluation of Cornea With Swept-Source Optical Coherence Tomography and Scheimpflug Imaging Before and After Lasik

      Abstract: Swept-source optical coherence tomography (OCT) is the latest advancement in anterior segment imaging. There are limited data regarding its performance after laser in situ keratomileusis (LASIK). We compared the reliability of swept-source OCT and Scheimpflug imaging for evaluation of corneal parameters in refractive surgery candidates with myopia or myopic astigmatism. Three consecutive measurements were obtained preoperatively and 1 year postoperatively using swept-source OCT and Scheimpflug imaging. The study parameters included central corneal thickness (CCT), thinnest corneal thickness (TCT), keratometry at steep (Ks) and flat (Kf) axes, mean keratometry (Km), and, anterior and posterior best fit spheres (Ant and Post ...

      Anterior Chamber Angle Imaging With Swept-Source Optical Coherence Tomography: Detecting the Scleral Spur, Schwalbe's Line, and Schlemm's Canal

      Objective: To determine the visibility of the scleral spur (SS), Schwalbe's line (SL), and Schlemm's canal (SC) imaged by a swept-source optical coherence tomographer (OCT). Methods: One eye from each individual was randomly selected from 30 normal subjects and 30 patients with primary open-angle glaucoma for anterior segment imaging with a swept-source OCT. The angles were imaged with 2 protocols: (1) high-density (HD, a raster of 64 B-scans each with 512 A-scans over 8 mm) and (2) low-density scans (LD, 128 radial scans each with 512 A-scans over 16 mm). The visibility of the angle structures was determined ...
