Role of Scheimpflug imaging for assessment of posterior lens capsule in pediatric traumatic cataract
Indian Journal of Ophthalmology, 2021 Purpose: To find the accuracy of Scheimpflug imaging for the evaluation of posterior lens capsule and to assess the incidence of pre-existing posterior capsular tear (PCT) in pediatric traumatic cataracts.

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

Ophthalmic Research, 2009 Conventional Scheimpflug photography uses slits with a constant width of 80 μm. 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 μm and less, using a green helium-neon laser (543 nm).

Scheimpflug lidar range profiling of bee activity patterns and spatial distributions
Animal Biotelemetry, 2022 Background Recent declines of honeybees and simplifications of wild bee communities, at least partly attributed to changes of agricultural landscapes, have worried both the public and the scientific community.
