About this study
This study is a masked, multi-center, daily wear, monthly replacement, bilateral, randomized, lens blocked (subjects remain in the same lens brand throughout the study) concurrent control study enrolling up to 90 subjects with a study duration of approximately three months. Subjects will be randomized into the study contact lenses in a two to one (2:1) ratio of fanfilcon A lens (test) to enfilcon A lens (control).
Read the detailed description
Subjects will be randomized into the study contact lenses in a two to one (2:1) ratio of fanfilcon A lens (test) to enfilcon A lens (control). This should result in a study population of approximately 60 test subjects and 30 control subjects.

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 8 Mar 2017). 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?
Epithelial Edema - Fanfilcon A Lens (Test) (time frame: Baseline, Week 1, Week 2, Month 1, Month 2, Month 3). The study lists 20 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 25 Sep 2019.
