On-Eye Evaluation of Contact Lens Axis Location
A study testing Delefilcon A toric contact lens T1, Delefilcon A toric contact lens T2 and Delefilcon A toric contact lens T3 in people with Myopia and Astigmatism, run by Alcon Research.
Trial summary
The purpose of this study was to evaluate the axis location of toric contact lenses after 3 minutes of wear. During this 1-visit study, each participant wore 3 pairs of study lenses of various design iterations (2-87-1, 2-87-2, 2-87-3) for an exposure time of approximately 30 minutes each.

About this study
The purpose of this study was to evaluate the axis location of toric contact lenses after 3 minutes of wear. During this 1-visit study, each participant wore 3 pairs of study lenses of various design iterations (2-87-1, 2-87-2, 2-87-3) for an exposure time of approximately 30 minutes each. Each pair consisted of lenses of the same design iteration, 1 lens with embossed mark [TEST1 (T1), TEST3 (T3), TEST5 (T5)], worn on the right eye, and 1 lens without embossed mark [TEST2 (T2), TEST4 (T4), and TEST6 (T6)] worn on the left eye.

What is being measured
The primary outcome is the main question the study is designed to answer.
Percentage of Lenses With Axis Orientation ≤ 10 Degrees From Ideal Location After 3 Minutes of Wear
Axis orientation (the rotational positioning of the lens on the eye) was indicated by an axis mark. The actual location of the axis mark was evaluated during slit lamp review and compared to the ideal location for the axis mark, with the difference measured in degrees (0 to +/- 180). The ideal location for the axis mark was iteration-specific (either 6 o'clock or 3 and 9 o'clock). This outcome measure was pre-specified for the embossed lenses only (TEST1, TEST3, and TEST5).
Measured: Day 1
Secondary outcomes (2)
Lens Awareness
Lens awareness was assessed by the participant on a 5-point scale (0=none and 4=severe) within the first 5 minutes of wear for each eye separately.
Measured: Day 1
Handling on Removal
Handling on removal (after 30 minutes of wear) was assessed by the participant on a scale from 1 to 10 (1=poor and 10=excellent). This outcome measure was pre-specified for the embossed lenses only (TEST1, TEST3, and TEST5).
Measured: Day 1

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The purpose of this study was to evaluate the axis location of toric contact lenses after 3 minutes of wear. During this 1-visit study, each participant wore 3 pairs of study lenses of various design iterations (2-87-1, 2-87-2, 2-87-3) for an exposure time of approximately 30 minutes each. Each pair consisted of lenses of the same design iteration, 1 lens with embossed mark [TEST1 (T1), TEST3 (T3), TEST5 (T5)], worn on the right eye, and 1 lens without embossed mark [TEST2 (T2), TEST4 (T4), and TEST6 (T6)] worn on the left eye.

Questions about this trial
What is this clinical trial studying?
A study testing Delefilcon A toric contact lens T1, Delefilcon A toric contact lens T2 and Delefilcon A toric contact lens T3 in people with Myopia and Astigmatism, run by Alcon Research.
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 3 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 16 May 2014. 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 16 May 2014). 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?
Percentage of Lenses With Axis Orientation ≤ 10 Degrees From Ideal Location After 3 Minutes of Wear (time frame: Day 1). 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 16 May 2014.
