Application of a New Scheimpflug Camera (EAS-1000) to Animal Cataract Models

Ophthalmic Research, 2009
A newly developed anterior eye segment system, EAS-1000, was applied to animal experiments. Since the device was developed to be used with human eyes, several minor changes were made to facilitate the use with animals. These changes included an animal-holding place instead of a chin rest, an additional monitor screen for help in alignment, a foot pedal

New equivalent keratometry reading calculation with a rotating Scheimpflug camera for intraocular lens power calculation after myopic corneal surgery

, 2014
PURPOSE: To calculate the keratometric (K) reading in corneas modified by myopic keratorefractive surgery using the total corneal refractive power (TCRP) of the Pentacam rotating Scheimpflug camera.

Stereo slit-scanning tomography of the anterior segment of the human eye

Scientific Reports
We demonstrate a new tomographic imaging device for 2D cross-sectional and 3D volumetric images of the anterior eye segment. The optical system combines optical sectioning with a stereoscopic camera setup to determine the true spatial location of the ...

Dynamic ultra high speed Scheimpflug imaging for assessing corneal biomechanical properties

Revista Brasileira de Oftalmologia, 2013
OBJECTIVE: To describe a novel technique for clinical characterization of corneal biomechanics using non-invasive dynamic imaging. METHODS: Corneal deformation response during non contact tonometry (NCT) is monitored by ultra-high-speed (UHS) photography.

Corneal power changes with Scheimpflug rotating camera after hyperopic LASIK

Medicine, 2018
Abstract To evaluate surgically induced refractive change (SIRC) by manifest refraction and corneal power changes using an automated keratometer and Scheimpflug rotating camera, and to find the best keratometric measurements reflecting SIRC after hyperopic laser-assisted in situ keratomileusis (LASIK).

Scheimpflug Camera Evaluation of Centration, Tilt and Lenticular Astigmatism of Scleral-Fixated Intraocular Lens: Flanged Haptic versus Double Flanged Suture Techniques

Zagazig University Medical Journal
Background: Scleral-fixated intraocular lens implantation is an important treatment option for aphakic eyes with inadequate capsular support. Accurate positioning of the intraocular lens is essential because intraocular lens (IOL) decentration, tilt, and

Evaluation of Scheimpflug imaging parameters in blepharospasm and normal eyes

BMC Ophthalmology, 2018
Background To investigate changes in corneal elevation, pachymetry, and keratometry in discriminating between normal and blepharospasm eyes, as measured by the Pentacam rotating Scheimpflug camera. Methods This was a prospective, cross-sectional study. A
