Predicting the Prognosis of Fuchs Endothelial Corneal Dystrophy by Using Scheimpflug Tomography.
Ophthalmology (Rochester, Minn.), 2020 PURPOSE To determine if Scheimpflug tomography pachymetry map and posterior elevation map patterns, central corneal thickness (CCT), and corneal backscatter can predict the prognosis of Fuchs endothelial corneal dystrophy (FECD). DESIGN Cross-sectional

The variability of corneal and anterior segment parameters in keratoconus [PDF]
, 2016 Purpose: To analyse, describe and test diverse corneal and anterior segment parameters in normal and keratoconic eyes to better understand the geometry of the keratoconic cornea. Method: 44 eyes from 44 keratoconic patients and 44 eyes from 44 healthy

Ophthalmic Research, 1996 Conventional Scheimpflug photography uses slits with a constant width of 80 microns. This parameter limits the resolution as sharp contours are imaged with a basic uncertainty. In order to reduce this basic uncertainty we developed an illumination slit with a width of 20 microns and less, using a green helium-neon laser (543 nm).

Fourier Ptychography with Scheimpflug Optics for Multi-Aperture Applications [PDF]
, 2017 We present a new optical configuration using the Scheimpflug principle for Fourier ptychography microscopy. This configuration minimizes the aberrations present in the off-axis lenses of a multi-aperture Fourier ptychography setup. A 3D printed setup was

Posterior corneal surface stability after femtosecond laser-assisted keratomileusis [PDF]
, 2015 The purpose of this study was to evaluate posterior corneal surface variation after femtosecond laser-assisted keratomileusis in patients with myopia and myopic astigmatism. Patients were evaluated by corneal tomography preoperatively and at 1, 6, and 12

Assessment of Age-related Cataract using Scheimpflug Imaging System and its Correlation with Phacoemulsification Parameters [PDF]
Journal of Clinical and Diagnostic Research, 2020 Introduction: Phacoemulsification has become the preferred treatment for cataract removal throughout the world. Therefore, it is important to assess cataract pre-operatively which could lead to a better organised and customised operative plan.
