Testing New Bifocal Toric Contact Lenses for Astigmatism
Part of Eyes & vision clinical trials.
This study evaluates how well new bifocal contact lenses work for people over 40 who have astigmatism (blurred vision at all distances) and need reading help. You'll wear the lenses daily for about a month and share feedback via text message to help researchers understand comfort and vision quality.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Age 40 or older and currently wear toric contact lenses (lenses that correct astigmatism)
- Have astigmatism between 0.75 and 2.50 diopters in each eye
- Need reading correction (presbyopia) of +0.75 or stronger
- Willing to wear the study lenses at least 13 hours daily for 29 days with no overnight wear
- Have worn reusable silicone hydrogel toric contact lenses in the past year without major discomfort
- No history of dry eye disease, eye surgery, eye infections, or serious eye conditions

Other trials that look related to this one.
This study tests two types of soft contact lenses that help with both distance and near vision. If you wear multifocal lenses or use a monovision setup, this trial may help find which lens works better for your daily activities.
This study compares two brands of multifocal contact lenses (lenses that help you see at multiple distances) in people over 40 who are currently happy with their INFUSE One-Day Multifocal lenses. Researchers want to see if switching to DAILIES TOTAL1 Multifocal lenses provides similar or better comfort and vision.
This trial tests if people who currently wear Acuvue Oasis contact lenses can switch comfortably to a new lens (P7) for astigmatism. It looks at how well the new lenses fit and how satisfied you are with them.
This study tests how well a new type of contact lens for astigmatism (a common condition that makes vision blurry) works in real life. You will wear the lenses and the study team will check your vision and eye health over time to see if the lenses fit well and are comfortable.
This study tests a new monthly contact lens that combines multifocal (for reading and distance) and toric (for astigmatism) features in a single lens. It's designed for people who need both distance and near vision correction and already wear soft contact lenses.
This study tests a special lens implant (toric lens) for people having cataract surgery who also have astigmatism. The lens corrects both the cataract and the astigmatism, potentially giving you clearer distance vision without glasses.
