Study shows vision-improvement for 83 percent of sample.
Researchers at the University of Wisconsin have found that a thin, corneal inlay improved the vision of more than 80 percent of patients enough that they could easily read a newspaper. “This is a solution that truly delivers near vision that transitions smoothly to far distance vision," said Dr. John Vukich of the research team. The 507 patients studied were between ages 45 and 60 and had presbyopia but were not considered nearsighted. After three years, 83 percent of the patients reported having 20/40 vision, which is required to pass a driver’s license test, or better, researchers said. Read the study here.
