Summary
"This trial will use the VIS Opti-K Low Vision Aid device to help improve vision for patients with refractive disorders like hyperopia and presbyopia."
Who is the study for?
This trial is for adults over 40 with presbyopia or farsightedness, who have a certain level of uncorrected and corrected visual acuity, need reading glasses of +1.0 to +3.0 D, and have normal corneal topography without significant cataracts. It's not for those with diabetes, glaucoma, high eye pressure, pregnancy, nystagmus (rapid eye movement), any corneal disease or past eye surgeries.
