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.
Backgound: Toric haptic scleral lens designs are prescribed more often than in previous years. Recent interest in mapping the sclera and conjunctiva is proving that scleral shape is highly variable and may explain the difficulty in fitting some patients with scleral lenses
