Rayner launches redesign of IOL calculator RayTrace

Rayner has announced the launch of a redesign for its online premium IOL calculator RayTrace.¹ Cited as one of the first online IOL calculation tools, RayTrace has been utilized globally by surgeons since 2008, according to a news release. The 4.0 version reflects surgeon feedback with quicker and clearer calculations, and allows access to the PEARL DGS formula, among other features.

“We’re delighted to kick off 2025 by bringing our new and improved RayTrace tool to surgeons around the world,” said Stanley Windsor, head of Digital Health at Rayner, in the release. “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.”

Other new features in RayTrace’s new version include the ability to calculate both eyes on one page, access toric and non-toric results in 1 calculation, improved theater view design, input post-operative refractive data, calculate the new RayOne Galaxy spiral IOL, and improved integration of Rayner’s PROMs platform, RayPRO.¹

RayTrace requires patient and surgeon information must be inputted in order to correct identify a patient’s calculation. Current refraction, biometry (including target refraction, axial length, method, and anterior chamber depth), and keratometry (including corneal curvature in K1/K2, agrees of axes, surgically induced astigmatism, incision location, and posterior corneal astigmatism) are all required data entry values that must be inputted into RayTrace. Optional data entry available includes lens thickness, central corneal thickness, white-to-white, and A-constant.²
