What is being measured
The primary outcome is the main question the study is designed to answer.
Distance Bright Illumination Binocular Visual Performance Reported as Visual Acuity
Tested with both eyes together in bright lighting, reading charts distant to the subject. This outcome is measured in logMAR units.LogMAR stands for the logarithm of the minimum angle of resolution. Ideal is 0.0 and represents 20/20 Snellen acuity. logMAR values > 0.00 indicate vision poorer than the ideal and values <0.00 indicate vision greater than the ideal.
Measured: 5 minutes after insertion
Near Bright Illumination Binocular Visual Performance Reported as Visual Acuity
Tested with both eyes together in bright lighting reading charts near to the subject. This outcome is measured in logMAR units.LogMAR stands for the logarithm of the minimum angle of resolution. Ideal is 0.0 and represents 20/20 Snellen acuity. logMAR values > 0.00 indicate vision poorer than the ideal and values <0.00 indicate vision greater than the ideal.
Measured: 5 minutes after insertion
Type of Corneal Staining
Investigator rated type of corneal staining as either 0=none, 1=micropunctate, 2=macropunctate, 3=coalesced, or 4=patch(> or = to mm).
Measured: after 1 week of lens wear, for each lens type
Overall Subjective Vision
Subject rated the overall quality of vision with the study contact lenses. 5=excellent, 4=very good, 3=good, 2=fair, 1=poor.
Measured: after 1 week of lens wear, for each lens type

Primary outcome
Distance Bright Illumination Binocular Visual Performance Reported as Visual Acuity
Time frame: 5 minutes after insertion
Tested with both eyes together in bright lighting, reading charts distant to the subject. This outcome is measured in logMAR units.LogMAR stands for the logarithm of the minimum angle of resolution. Ideal is 0.0 and represents 20/20 Snellen acuity. logMAR values > 0.00 indicate vision poorer than the ideal and values <0.00 indicate vision greater than the ideal.
Near Bright Illumination Binocular Visual Performance Reported as Visual Acuity
Time frame: 5 minutes after insertion
Tested with both eyes together in bright lighting reading charts near to the subject. This outcome is measured in logMAR units.LogMAR stands for the logarithm of the minimum angle of resolution. Ideal is 0.0 and represents 20/20 Snellen acuity. logMAR values > 0.00 indicate vision poorer than the ideal and values <0.00 indicate vision greater than the ideal.
Type of Corneal Staining
Time frame: after 1 week of lens wear, for each lens type
Investigator rated type of corneal staining as either 0=none, 1=micropunctate, 2=macropunctate, 3=coalesced, or 4=patch(> or = to mm).
Overall Subjective Vision
Time frame: after 1 week of lens wear, for each lens type
Subject rated the overall quality of vision with the study contact lenses. 5=excellent, 4=very good, 3=good, 2=fair, 1=poor.

Questions about this trial
What is this clinical trial studying?
A study testing balafilcon A, senofilcon A production and senofilcon A test in people with Presbyopia, run by Johnson & Johnson Vision Care, Inc. at 1 site in United States.
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 11 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

The record says: finished, as of the sponsor's last update on 19 Jun 2018. 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 States. 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 26 Aug 2010). 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 Bright Illumination Binocular Visual Performance Reported as Visual Acuity (time frame: 5 minutes after insertion). The study lists 4 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 19 Jun 2018.
