New contact lens aims to simplify vision for astigmatism and presbyopia
NCT ID NCT06377488
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested a new daily disposable contact lens designed for people with astigmatism (blurry vision from an irregularly shaped cornea) and presbyopia (age-related difficulty seeing up close). 176 adults aged 40-70 wore the lens for one week. Researchers measured how well they could see at different distances and how comfortable the lens was. The goal was to see if this single lens could correct both vision problems effectively.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- daily disposable silicone hydrogel multifocal toric contact lens
- What this could lead to
- If successful, this lens could offer a more comfortable and convenient option for people who need both astigmatism and reading correction in one lens.
- What could go wrong
- This was a small, completed trial focused on vision performance, not a cure or treatment for any eye disease. Results may not apply to all lens wearers.

Inclusion Criteria: Potential subjects must satisfy all of the following criteria to be enrolled in the study: 1. Read, understand, and sign the STATEMENT OF INFORMED CONSENT and receive a fully executed copy of the form. 2. Appear able and willing to adhere to the instructions set forth in this clinical protocol. 3. Be at least 40 and not more than 70 years of age at the time of screening. 4. Own a wearable pair of spectacles if required for their distance vision. 5. Be an adapted soft contact lens wearer in both eyes (i.e. worn lenses for at least 8 hours per day at least two days per week for the past 4 weeks). 6. Be already wearing a presbyopic contact lens correction (e.g., reading spectacles over contact lenses, multifocal or monovision contact lenses, etc.) or if not respond positively to at least one symptom on the "Presbyopic Symptoms Questionnaire". 7. The subject's distance spherical component of their refraction must be in the range of either -1.25 D to -3.75 D, or +1.25 D to +4.25 D. 8. The subject's refractive cylinder must be in the range of -1.00 D to -1.75 D in each eye, with the cylinder axes in the range of either 90°±15° or 180°±15°. 9. The subject's ADD power must be in the range of +0.75 D to +2.50 D in each eye. 10. The subject must have best corrected distance visual acuity of 20/20-3 or better in each eye. Exclusion Criteria: Potential subjects who meet any of the following criteria will be excluded from participating in the study: The subject must not: 1. Be currently pregnant or lactating. 2. By self-report, have any systemic disease (e.g. Sjögren's Syndrome), allergies, infectious disease (e.g., hepatitis, tuberculosis), contagious immunosuppressive diseases (e.g., HIV), autoimmune disease (e.g. rheumatoid arthritis), or other diseases, which are known to interfere with contact lens wear and/or participation in the study. 3. Use systemic medications that may interfere with contact lens wear or cause blurred vision. See Section 9.1 for additional details regarding excluded systemic medications. 4. Currently use ocular medication (with the exception of rewetting drops). 5. Have any known hypersensitivity or allergic reaction to single use preservative free rewetting drops or sodium fluorescein. 6. Have had any previous, or have any planned, ocular or intraocular surgery (e.g. radial keratotomy, PRK, LASIK, cataract surgery, retinal surgery, etc.). 7. Have had previous eyelid injuries, surgeries or procedures which are known to have caused abnormal eyelid position or movement, by self-report. 8. Have participated in any contact lens or lens care product clinical trial within 7 days prior to study enrollment. 9. Be an employee or immediate family member of an employee of clinical site (e.g., Investigator, Coordinator, Technician). 10. Have a history of amblyopia or strabismus, by self-report. 11. Have a history of herpetic keratitis, by self-report. 12. Have ocular allergies, infections or other ocular abnormalities that are known to interfere with contact lens wear and/or participation in the study. This may include, but not be limited to entropion, ectropion, chalazia, recurrent styes, glaucoma, history of recurrent corneal erosions, aphakia, or corneal distortion. 13. Have any Grade 3 or greater slit lamp findings (e.g., edema, corneal neovascularization, corneal staining, tarsal abnormalities, conjunctival injection) on the FDA scale.
