Two toric lenses go head to head in vision test
NCT ID NCT05320042
First seen Sep 17, 2026 · Last updated Sep 18, 2026 · Updated 1 time
Summary
Researchers compare kalifilcon A daily disposable toric contact lenses with Ultra for Astigmatism lenses in adults who already wear soft contacts and need astigmatism correction. Each participant wears both lens types for about one week each, in random order. The study measures how well each lens corrects vision.
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 toric contact lenses
- What this could lead to
- If kalifilcon A lenses perform well, they could offer another daily disposable option for people with astigmatism.
- What could go wrong
- This is a small, short study of 35 experienced lens wearers, so results may not apply to everyone. Contact lenses can cause discomfort, dryness, or rare serious eye infections.
