EyePrint Prosthetics’ custom scleral lens for horizontal diplopia

US-based EyePrint Prosthetics’ has made a custom scleral lens to correct horizontal diplopia. The lens uses the global toricity of the ocular surface and patented elevation-specific technology to create a custom-fit, said the company.

The lens achieves 360° of tangential landing on scleral curvature without lifting or depression areas, said San Antonio optometrist Dr Melanie Frogozo after trialling the lens on a patient. Her patient was looking for a contact lens (CL)-only option as he was tired of wearing CLs with prismatic glasses to correct horizontal double vision, she said. “It’s particularly useful for quickly and accurately fitting patients with atypical ocular curvature due to keratoconus, trauma, extreme ocular deformity, pellucid marginal degeneration, chemical burns, post-surgical corneas, pinguecula, pterygium or stem cell failure.” The lens hugs every curve of the eye, does not rotate and is stable enough to allow for the incorporation of an optical prism in any base direction, she said.

EyePrint Pro’s Gabi von Roedern said the company hopes to introduce the lenses to Australia and New Zealand next year.
