Cabot F, Gatinel D. cataract or crystalline clear: objective evaluation methods and surgical indication, ophthalmological realities, December 2013

This article is about the problem related to the objective definition of cataract. The current diagnostic criteria are obsolete and/or subjective, and thresholds of Visual acuity unsuited to Visual annoyance felt by patients with cataract beginner, especially when there is a large light distribution by the opacities of the lens, but with [...]

D Gatinel.Qu' is a clear lens? Ophthalmological realities, March 2012

Clear lens or cataract? Cataract diagnosis is based on the combination of Visual symptoms and signs of the biomicroscope (slit lamp) examinations. The variability of the Visual signs of cataracts (loss of Visual acuity, but also glare, difficulties against day), as well as the anatomical continuum that connects clear lens and advanced cataract are [...]

What is the OQAS instrument?

OQAS (Optical Quality Analyzing System, designed by the Spanish company Visiometrics) is an instrument that provides the direct measure of the combined effect of optical aberrations of high degree and the loss of transparency of the eye circles on the optical quality of the eye. It is of major interest in cataract surgery, but [...]

Saad A, Saab M, Gatinel D. Repeatibility of measurements with a double-pass system.

The purpose of this study was to establish the repeatability of the measurement of intraocular diffusion by double-pass aberrométrie. Intraocular luminous diffusion is caused by the reduction of the transparency of the ocular media. Cataract is a condition whose symptoms are partly caused by increased intraocular diffusion: veil, halos of [...]

Ganeshan D. Imaging and quantification of intraocular light scattering in anterior segment pathology

The increase in intraocular luminous diffusion ("scattering") is a phenomenon observed in many ophthalmological pathologies, which have as a common point to induce a reduction of the transparency of one or more ocular environments. Cataracts, contact opacities, vitreous opacities, anomalies of the flap interface after LASIK, Microfolds of flap, are all clinical situations or [...]
