What is being measured
The primary outcome is the main question the study is designed to answer.
Subjective Reported Vision
A weighted combined score of one week and two week data calculated from individual vision-related questions asked on a 1-5 scale, 1 = most negative response to 5 = most positive, was used to derive vision outcomes. The analysis shows the outcome for both senofilcon A and alphafilcon A. If score >0 then greater vision, if <0 then lesser vision.
Measured: 1 week
Subject Reported Lens Comfort.
A weighted combined score of one week and two week data calculated from individual comfort-related questions asked on a 1-5 scale, 1=most negative response to 5=most positive response, was used to derive comfort outcomes. The analysis shows the estimates for senofilcon A and alphafilcon A, respectively. Interpretation is >0 indicates comfortable and <0 indicates uncomfortable.
Measured: 1 week

Questions about this trial
What is this clinical trial studying?
A study testing senofilcon A toric and alphafilcon A toric in people with Astigmatism, run by Johnson & Johnson Vision Care, Inc..
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 0 inclusion and 15 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 21 May 2015. 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 19 Feb 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?
Subjective Reported Vision (time frame: 1 week). The study lists 2 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 21 May 2015.
