Optical Coherence Tomography (OCT) is a non-invasive, non-contact imaging modality used to visualize and monitor changes to the morphology of biological tissue. OCT employs low-coherence interferometry to create cross-sectional images that reveal sub-surface details of the tissues of interest. In the most common ophthalmic applications OCT systems use near-infrared light to generate high-resolution, volumetric images of tissue microstructures including the cornea, iris, crystalline lens, vitreous and retina. These images can enhance insight into pathological conditions such as glaucoma, age-related macular degeneration or diabetic retinopathy. https://www.leica-microsystems.com//science-lab/what-is-oct-and-how-can-it-help-ophthalmologists-acquire-high-resolution-information-on-ocular-tissue/ Thu, 01 Dec 2016 14:44:00 +0000 George Wildeman, PhD Hafeez Dhalla https://www.leica-microsystems.com/18978 Optical Coherence Tomography Surgical Microscopy How Intrasurgical OCT can Provide Additional Information During Ophthalmic DMEK Procedures Replacing diseased Descemet’s membrane with a donor graft is an especially delicate procedure. Accurate positioning and full adherence to the stroma are crucial for optimal patient outcomes. These videos illustrate how intrasurgical OCT can provide additional information during each stage of a DMEK procedure. https://www.leica-microsystems.com//science-lab/how-intrasurgical-oct-can-provide-additional-information-during-ophthalmic-dmek-procedures/ Thu, 01 Dec 2016 14:05:00 +0000 Marie Stockton https://www.leica-microsystems.com/18307 Surgical Microscopy "The excellent red reflex, combined with the IOL guidance system, makes it possible for me to work quickly and precisely during refractive procedures." Excellent red reflex as well as maximum accuracy throughout the entire procedure are required to meet these expectations. Dr. Ulrich Jung, Medical Director at the ARTEMIS eye clinic in Dillenburg, Germany, tested the Proveo 8 ophthalmological microscope from Leica Microsystems in combination with the positioning system IOLcompass Pro for intraocular lenses at his clinic. In this interview, Dr. Jung reports his experiences. https://www.leica-microsystems.com//science-lab/the-excellent-red-reflex-combined-with-the-iol-guidance-system-makes-it-possible-for-me-to-work-quickly-and-precisely-during-refractive-procedures/ Fri, 24 Jun 2016 11:40:00 +0000 Dr. med.

Yoo: Interoperative OCT Imaging of Selective Lamellar Keratoplasty The work prepared and presented within this video demonstrates preliminary research, and the promising future of perioperative OCT to aid the diagnosis of physiological and pathological conditions during ophthalmic surgery in order to help guide surgical decision making in anterior segment cases. Showing SDOCT Images acquired with an Envisu SD-OCT system, Prof. Yoo demonstrates the use of interoperative OCT imaging several important surgical procedures such as DALK, DSAEK and DMEK. https://www.leica-microsystems.com//science-lab/video-talk-by-sonia-h-yoo-interoperative-oct-imaging-of-selective-lamellar-keratoplasty/ Mon, 09 Nov 2015 13:07:00 +0000 Prof. Sonia H.
