  • The subject currently is a habitual wearer of spherical or toric daily-wear soft contact lenses, excluding daily disposables, in daily wear bases.

Who cannot join

  • The subject has any ocular or systemic allergies that interfere with contact lens wear.
  • The subject has dry eye and lacrimal apparatus disease that could interfere with contact lens wear.
  • The subject has any systemic disease or autoimmune disease that interferes with contact lens wear.
  • The subject has corneal edema, neovascularization, corneal staining or other ocular abnormalities (Grade 3 or above) that clinically apparently interfere with contact lens wear.
  • The subject has any anterior segment eye disease (palpebral abnormalities, corneal hypesthesia, corneal epithelial defect, bulbar conjunctival hyperemia, etc.) that clinically apparently interferes with contact lens wear.
  • The subject has a history of solution reactions to the chemical cleaner/disinfectant to be used in this study, as far as known to the subject.

  • The subject has ocular infection.
  • The subject has ocular inflammation (including acute/subacute anterior segment inflammations and uveitis).
  • The subject has corneal distortion resulting from previous experience of hard contact lens wear.
  • The subject has infectious disease (pneumonia, tuberculosis, etc.) or immunosuppressive disease (HIV positive etc.), as far as known to the subject.
  • The subject has diabetes, as far as known to the subject.
  • The subject is pregnant or in the lactation period, as far as known to the subject.

  • The subject is a wearer of hard contact lenses (including rigid gas permeable).
  • The subject is exposed to a dry environment on a constant basis.
  • The subject is exposed to a living environment where dust, chemicals, etc. can easily enter the eye.
  • The subject is unable to follow the principal investigator's instructions.
  • The subject is unable to follow lens hygiene procedures necessary for contact lens wear.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Subject-reported satisfaction for vision

    Scale of 0 to 100, were 0=extremely poor and 100=Excellent

    Measured: After 2 weeks of lens wear

  2. Subject-reported satisfaction for comfort.

    Scale of 0 to 100, were 0=extremely poor and 100=Excellent

    Measured: After 2 weeks of lens wear

Secondary outcomes (1)
  1. Subject preference for lens type.

    Measured: After 2 weeks of lens wear.

Questions about this trial

What is this clinical trial studying?

A study testing senofilcon A toric soft contact lens and senofilcon A sphere soft contact lens in people with Refractive Error and Myopia, run by Johnson & Johnson Vision Care, Inc. at 10 sites in Japan.

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 19 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: stopped early, as of the sponsor's last update on 29 Oct 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 10 sites in Japan. Whether a site is taking part right now should be confirmed with that site. See every site.

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?

The study was stopped early (reason given: English to Japanese translation issues caused enrollment of incorrect and unqualified subjects; error applied to all subjects enrolled prior to termination.). Results are not available in the source record.

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?

Subject-reported satisfaction for vision (time frame: After 2 weeks of lens wear). 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 29 Oct 2014.
