What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Binocular High Contrast/High Illumination (HC/HI) Visual Acuity (VA) at Intermediate Distance (80 cm)

    Visual Acuity (clarity or sharpness of vision) was measured at high contrast level. HC/HI VA was assessed binocularly (both eyes together) at 80 centimeters using an Early Treatment Diabetic Retinopathy Study (ETDRS) chart and measured in logarithm of the minimum angle of resolution (logMAR). A lower logMAR value indicates better visual acuity.

    Measured: Day 14, each product

Secondary outcomes (1)
  1. Contact Lens Dry Eye Questionnaire-8 (CLDEQ-8) Score

    The abbreviated CLDEQ-8 is an 8-item questionnaire used to assess comfort and dryness. Total CLDEQ-8 score ranged from 0 to 37, where a lower score represented less symptomology.

    Measured: Day 14, each product

Questions about this trial

What is this clinical trial studying?

A study testing Delefilcon A multifocal contact lenses and Habitual multifocal contact lenses in people with Refractive Error, run by Alcon, a Novartis Company.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 2 Jul 2018. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 24 Nov 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Binocular High Contrast/High Illumination (HC/HI) Visual Acuity (VA) at Intermediate Distance (80 cm) (time frame: Day 14, each product). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Jul 2018; AzTrials last refreshed its copy on 7 Nov 2026.
