Matching Scleral Design with Ocular Shape – Advancements in measurements and manufacturing can improve fitting efficiency and success.
The majority of practitioners fitting scleral contact lenses rely on diagnostic lenses for fitting. Diagnostic lenses primarily allow practitioners to estimate the amount of sagittal depth needed to properly vault the chord diameter of the ocular surface that is being fit.
Visionary Optics recently introduced the Latitude scleral lens. According to the company’s research, most patients’ corneal and scleral shapes do not conform to scleral lens designs based upon peripheral curve systems. Its answer to this dilemma was to create the Latitude lens, which has no peripheral curve system; rather, it is a freeform lens designed to contour uniformly to each eye.
