The Scleral Lens Vector Translator is an innovative software tool designed to enhance the precision of scleral lens fitting. The process begins with the clinician capturing a photograph of the patient’s eye while they are wearing a specially designed scleral lens. Using the accompanying software, the Scleral Lens Alignment Checker, the clinician evaluates key parameters including the pupillary axis, lens decentration, and lens rotation. This data provides a comprehensive understanding of the lens’ position relative to the patient’s visual anatomy.

The Scleral Lens Vector Translator takes this analysis a step further by isolating the vector defining the scleral lens’ central axis and comparing it to both the pupillary and visual axes. By solving a system of equations, the software determines the precise adjustments needed to align the optical center of the lens with either the pupillary or visual axis. This powerful tool improves lens fitting accuracy, ensuring optimal visual outcomes for patients and streamlining the fitting process for clinicians.
