Selecting the right implantable phakic lens just got safer. The ArcScan Insight 100’s ICL sizing capability allows clinicians to reduce the risk of size-related complications by selecting a lens based on direct measurements of the posterior chamber. By producing crystal-clear “HD” images (versus the “analog” efforts of other ultrasound biomicroscopy systems), measurement accuracy is assured to within 1.0 µm at the cornea and 0.12 mm laterally behind the iris.
How? Thanks to the ArcScan Insight 100’s ability to maintain a consistent perpendicularity and distance from the eye with its robotically-controlled transducer, and its automatic focal depth settings. Each preoperative imaging scan set includes seven meridians to cover the desired area of the lens footplate location. And the resulting images not only help determine the exact lateral space, they can also be used to detect the presence of ciliary cysts or other pathologies, aiding surgical planning.
Dan Reinstein, Founder of the London Vision Clinic and Chief Medical Officer at ArcScan, is the man behind the innovation. Here, he explains how the precise measurement capability of the Insight 100 increases confidence in ICL sizing: “OCT-based formulae with anterior chamber dimensions have improved on the STAAR recommended white-to-white formula, but posterior chamber dimensions have improved yet further the predictability of postop ICL vault. Lovisolo, Dougherty, and Kojima derived sulcus-to-sulcus based formulae, but the Reinstein Formula utilizes an even better predictor: the ciliary body inner diameter.” The calculator can be found at iclsizing.com.
Roger Zaldivar, Founder of the Instituto Zaldivar, speaks highly of the device’s new capability: “I can’t emphasize enough how important the ArcScan is today in our practice for ICL sizing. It will soon be the global gold standard in sizing.”
