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.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
kalifilcon A daily disposable multifocal contact lenses
What this could lead to
If these lenses perform well, they could offer a more comfortable and convenient option for people with presbyopia who need help seeing both near and far.
What could go wrong
This is a small, short-term study, so results may not apply to everyone. Some people may find the lenses less comfortable or not as sharp as their usual ones.
