Rayner, a global manufacturer of products for cataract surgery, today announces the launch of its redesigned online premium IOL calculator, RayTrace.

One of the first online IOL calculation tools, RayTrace has been trusted by surgeons globally since 2008 for the accuracy of its premium IOL (toric, multifocal and supplementary) calculations, and has delivered over 360,000 since launch. The newly-redesigned RayTrace version 4.0 reflects surgeon feedback with quicker and clearer calculations, access to the PEARL DGS formula, and a number of other new features:

• Ability to calculate both eyes on one page


• Access Toric and non-Toric results in one calculation


• Improved theatre view design


• Input post-operative refractive data


• Calculate the new RayOne Galaxy spiral IOL


• Improved integration with Rayner’s best-in-class PROMs platform, RayPRO

Stanley Windsor, Head of Digital Health at Rayner, said “We’re delighted to kick off 2025 by bringing our new and improved RayTrace tool to surgeons around the world. Thank you to our dedicated group of KOLs who provided valuable feedback to inform the redesign – the latest features will really improve usability for surgeons to ensure quick, clear calculations. We look forward to seeing the impact of RayTrace 4.0 as we continue to drive digital innovation in ophthalmology this year.”
