New contact lenses promise more comfort for aging eyes
NCT ID NCT07586982
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether Total30 multifocal toric contact lenses are more comfortable and provide better vision than current lenses for people with presbyopia (age-related blurry near vision). 32 adults aged 40 and older who already wear toric contacts will try the new lenses for one month. Researchers will measure comfort and dryness using questionnaires and vision tests.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Total30 multifocal toric contact lenses
- What this could lead to
- If successful, this could show that Total30 lenses provide better comfort and vision for people with presbyopia who already wear toric contacts.
- What could go wrong
- This is a small, early-stage study with only 32 participants, so results may not apply to everyone. Comfort is subjective and may not improve for all.

Inclusion Criteria: * Adults, ≥40-year-old, CL wearers with best-corrected 20/20 distance visual acuity or better. * Requiring +0.75 ADD or more at standard near distance of 40 cm. * Participants will be required to have worn reusable silicone hydrogel toric CLs in the past year and still at a minimum wearing the CLs occasionally without having significant discomfort or dryness. * All participants will be required to have a CLDEQ-8 score \<12. * Participants will be required to be able to wear Total 30MFT CLs (presbyopic plus astigmatism both ≥0.75D OD and OS). * Astigmatism ranging from 0.75 D to 2.50 D in each eye. * Participants will be required to wear the study CLs for ≥13 hours each day with no overnight wear. * Willing to wear study CLs for ≥16 hours on the Day 1 (1st full day), Day 14, and Day 29 when responses will be collected via text message. * Participants will be willing to wear the CL every day of the week. * Participants will be required to provide a glasses prescription that is less than 3 years old. * Visual acuity with habitual reusable silicone hydrogel toric CLs is 20/25 or better in each eye. Exclusion Criteria: * Have worn Total30 MFT in the past * Are past rigid CL wearers * Are currently wearing monovision CLs * Have a history of being diagnosed with dry eye or ocular allergies * Have known systemic health conditions that are thought to alter tear film physiology * Have a history of viral eye disease * Have a history of ocular surgery * Have a history of severe ocular trauma * Have a history of corneal dystrophies or degenerations * Have active ocular infection or inflammation * Are currently using isotretinoin-derivatives or ocular medications * Are pregnant or breast feeding
