What is being measured
The primary outcome is the main question the study is designed to answer.
Overall Comfort
Overall comfort was assessed and reported by the participant on a questionnaire as a single, retrospective evaluation of 2 weeks of wear. Overall comfort was measured on a 10-point scale, with 1 being poor and 10 being excellent.
Measured: 2 weeks
Overall Comfort
Overall comfort was assessed and reported by the participant on a questionnaire as a single, retrospective evaluation of 4 weeks of wear. Overall comfort was measured on a 10-point scale, with 1 being poor and 10 being excellent.
Measured: 4 weeks
End of Day Dryness
End of day dryness was assessed and reported by the participant on a questionnaire as a single, retrospective evaluation of 2 weeks of wear. End of day dryness was measured on a 10-point scale, with 1 being very dry and 10 being not dry.
Measured: 2 weeks
End of Day Dryness
End of day dryness was assessed and reported by the participant on a questionnaire as a single, retrospective evaluation of 4 weeks of wear. End of day dryness was measured on a 10-point scale, with 1 being very dry and 10 being not dry.
Measured: 4 weeks
Ocular Redness
Ocular redness was assessed and reported by the participant on a questionnaire as a single, retrospective evaluation of 2 weeks of wear. Ocular redness was measured on a 10-point scale, with 1 being very red and 10 being not red.

Measured: 4 weeks
Lens Deposits
Protein and lipid deposits on the contact lens surface were assessed for each eye by the investigator using a biomicroscope, which magnifies the appearance of the contact lens on the wearer's eye. Deposits were graded on a scale of 0 to 4, with 0 being none and 4 being severe.
Measured: 2 weeks

Measured: 4 weeks
Corrected Visual Acuity
Each eye was tested individually while the participant read distant charts in normal lighting. Corrected visual acuity was measured using a Snellen chart, which was converted into logMAR units (logarithm of the minimum angle of resolution). A 20/20 Snellen acuity equates to a logMAR acuity of 0.0 and is considered normal distance eyesight. Positive logMAR values indicate poorer vision, and negative values denote better visual acuity.

Questions about this trial
What is this clinical trial studying?
A study testing lotrafilcon B contact lens in people with Myopia and Astigmatism, run by CIBA VISION.
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 5 inclusion and 7 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 10 Jul 2012. 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 1 Jun 2012). 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?
Overall Comfort (time frame: 2 weeks). The study lists 12 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 10 Jul 2012.
