- Conditions
- Visual Acuity
- Being tested
- etafilcon A
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.

Marketed Multifocal Contact Lens
| Study group | Role | What they receive |
|---|---|---|
| Study Lens (etafilcon A) for Multifocal | Experimental | All Subjects in this study will wear the same contact lenses. However subjects wil be stratified as Hyperopes or Myopes using a 1:1 allocation. The study lens will be worn for a period of approximately 4 hours to allow lenses to settle on the eyes.

What is being measured
The primary outcome is the main question the study is designed to answer.
Distance Binocular LogMAR Visual Acuity

Measured: 4 Hr. Post Fitting
Near Binocular LogMAR Visual Acuity
Near Binocular LogMAR Visual Acuity was measured at 40cm for Low luminance ( 2.5 CD/M^2 ), Medium luminance ( 50 CD/M^2 ) and High luminance ( 250 CD/M^2 )
Measured: 4 Hr. Post Fitting
Intermediate Binocular LogMAR Visual Acuity
intermediate Binocular LogMAR Visual Acuity was measured at 67cm for Low luminance ( 2.5 CD/M^2 ), Medium luminance ( 50 CD/M^2 ) and High luminance ( 250 CD/M^2 )
Measured: 4 Hr. Post Fitting

Questions about this trial
What is this clinical trial studying?
A study testing etafilcon A in people with Visual Acuity, run by Johnson & Johnson Vision Care, Inc. at 1 site in United Kingdom.
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 8 inclusion and 14 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 15 Sep 2016. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.
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 15 Sep 2016). 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?
Distance Binocular LogMAR Visual Acuity (time frame: 4 Hr. Post Fitting). The study lists 3 primary outcomes in all. 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 15 Sep 2016.
