Can a new contact lens sharpen both near and far vision for aging eyes?
NCT ID NCT05325931
First seen Aug 06, 2026 · Last updated Aug 07, 2026 · Updated 1 time
Summary
This trial tests whether a new daily disposable multifocal contact lens (kalifilcon A) can provide clear vision at both distance and near compared to an existing lens (samfilcon A) in people with presbyopia, the age-related loss of near vision. Adults aged 40 and older who already wear soft contact lenses will wear each type for about a week, and their visual sharpness will be measured. The study aims to see if the new lens offers a better option for managing presbyopia.
