What participants receive. In a randomised study each person is assigned to one group by chance.
delefilcon A contact lensDevice
Investigational silicone hydrogel, single vision soft contact lens
narafilcon B contact lensDevice
Commercially marketed silicone hydrogel, single vision soft contact lens
| Study group | Role | What they receive |
|---|---|---|
| delefilcon A | Experimental | Investigational contact lenses worn in both eyes on a daily wear, daily disposable basis for 3 months. Receives: Device: delefilcon A contact lens |
| narafilcon B | Active comparator | Commercially marketed contact lenses worn in both eyes on a daily wear, daily disposable basis for 3 months. Receives: Device: narafilcon B contact lens |
What is being measured
The primary outcome is the main question the study is designed to answer.
Corrected Distance Monocular Visual Measurement in Normal Illumination Reported as Visual Acuity
Each eye tested individually while reading a chart distant to the participant in normal lighting. Visual acuity was measured using a Snellen chart, with 20/20 Snellen acuity considered normal distance-eyesight. Visual acuity is reported as the number of eyes achieving 20/20 Snellen acuity or better.
Measured: 3 months of wear, lenses replaced daily
Secondary outcomes (3)
Overall Vision
As interpreted by the participant and recorded on a questionnaire as a single, retrospective evaluation of 3 months of wear time. Overall vision was evaluated binocularly and rated on a 10-point scale, with 1 being poor and 10 being excellent.
Measured: 3 months of wear, lenses replaced daily
Overall Comfort
As interpreted by the participant and recorded on a questionnaire as a single, retrospective evaluation of 3 months of wear time. Overall comfort was evaluated binocularly and rated on a 10-point scale, with 1 being poor and 10 being excellent.
Measured: 3 months of wear, lenses replaced daily
Overall Handling
As interpreted by the participant and recorded on a questionnaire as a single, retrospective evaluation of 3 months of wear time. Overall handling was evaluated binocularly and rated on a 10-point scale, with 1 being poor and 10 being excellent.
Measured: 3 months of wear, lenses replaced daily

Questions about this trial
What is this clinical trial studying?
A study testing delefilcon A contact lens and narafilcon B contact lens in people with Myopia, run by CIBA VISION.

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 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 20 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?
Corrected Distance Monocular Visual Measurement in Normal Illumination Reported as Visual Acuity (time frame: 3 months of wear, lenses replaced daily). 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.
