Digital photography of the iris, including iris retro-illumination, was obtained with a Nikon D1X camera mounted to a Topcon 8Z slit lamp using IMAGEnet 2000 digital imaging A new treatment, UV corneal collagen cross-linking (CXL), has been recently introduced to reduce the progression of noninflammatory corneal degeneration such as keratoconus, pellucid marginal degeneration, and ectatic corneal disorders after corneal refractive procedures. 1-3 The treatment consists of CXL by the photosensitizer riboflavin and UV-A light preceded by corneal epithelial removal. 4 Orbscan computerized topography: Attributes, applications, and limitations.

Jun 08, 2020 · Previously, in normal corneas a correlation between UP and SST (Orbscan II) was shown [ 17, 18 ]. As being a non-contact method, Orbscan was reported as a repeatable technique; however, the device systematically overestimated CCT compared with other devices [ 19, 20, 21 ]. Orbscan II can provide plenty of data, 11 and it is known that, as the number of variables used to train a learning method increases, so does the amount of information available.

The corneal radiuses of curvature were measured by the Orbscan II topographer, which operates on the principle that light rays. Nov 26, 2010 · Although Orbscan II is not commonly used to measure anterior chamber depth, it has proved to be useful and accurate with the advantage of being non-invasive, repeatable, and precise when compared Studies have shown that time-domain 23,24 and Fourier-domain 24,25 OCT devices are reliable for repeated measurements of corneal thickness. The non-contact Nidek NT 530P Tonopachy is a reliable tonometer when compared with the clinical gold standard Goldmann applanation tonometer. 42 The method used to determine and classify the SE in this study has been used previously.

Keratoconus early detection (screening) and diagnosis requires an in-deep corneal analysis with different techniques available.1 Slip lamp assessment and corneal topography/tomography are the most commonly accepted techniques in eye examination. Corneal topography and corneal tomography are useful terms that distinguish between two different types of corneal examination, so both will coexist Zistili sme, že meranie hrúbky rohovky prístrojom Orbscan II a IOT bezkontaktnou metódou je nepresné u pacientov po CXL. Záver: Corneal cross-linking rohovky je bezpečný a účinný výkon zastavujúci progresiu keratokónusu u 97% očí v čase 2 roky po výkone.
