New contact lens trial aims to simplify presbyopia prescriptions
NCT ID NCT07600645
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study will test a new fitting experience for multifocal contact lenses in 25 people with presbyopia (age-related blurry near vision). Participants, who already wear certain contact lenses, will use an at-home trial kit with the new lens for 15 minutes daily. The goal is to see if this approach helps them finalize a prescription more easily.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- stenfilcon A contact lens (device)
- What this could lead to
- If successful, this could make it easier for people with presbyopia to get a comfortable multifocal contact lens prescription.
- What could go wrong
- This is a very small, early-stage study with only 25 participants. It focuses on the fitting experience, not on long-term vision improvement or safety.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. They are at least 40 years of age. 2. They understand their rights as a research participant and are willing and able to sign a Statement of Informed Consent. 3. They habitually wear MyDay sphere or MyDay Energys contact lenses (including sphere lenses for monovision, or sphere lenses for distance vision correction and spectacles for near vision correction). 4. They have a minimum reading add of +0.75DS (based on their manifest refraction) and no more than +2.50DS. 5. They have spherical equivalent refractive error between +4.50 to -11.00DS (some restrictions apply based on near add availability) 6. They have refractive astigmatism of no greater than 0.75DC in each eye. 7. They are able to achieve distance HCHL visual acuity of +0.10 logMAR or better in each eye with manifest refraction. 8. They report at least one near-vision difficult symptom consistent with presbyopia as evidenced by a response of 'slight difficult' or worse on ³ 1 item of the Near Activity Visual Questionnaire (NAVQ-P) at screening. Exclusion Criteria: 1. Is participating in any concurrent clinical or research trial. 2. They have an ocular disorder which would normally contraindicate contact lens wear. 3. They have a systemic disorder which would normally contraindicate contact lens wear. 4. They are pseudophakic or aphakic. 5. They have had corneal refractive surgery. 6. They have any corneal distortion resulting from previous hard or rigid lens wear or have keratoconus. 7. Is using any systemic or topical medications that in the opinion of the investigator may affect contact lens wear or a study outcome variable. 8. Self-reports as pregnant, lactating or planning a pregnancy at the time of enrollment.
