Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 15 years and older
  • All sexes
  • Healthy volunteers accepted
  • Child, Adult, Older adult

Who may be able to join

  • The patient must be at least 15 years old.
  • The patient must be free of any anterior segment disorders.
  • The patient must have a spectacle corrected spherical refractive error between +5.50 D and -11.00 D with less than or equal to 1.00 D refractive cylinder.
  • The patient must be correctable to 20/25 or better with spectacles.
  • Flat and steep corneal curvatures from Simulated Keratometry readings must be between 39.00 and 48.00 D.
  • Can be successfully fit with lotrafilcon A lenses at the enrollment visit.

Who cannot join

  • The patient has worn rigid gas permeable lenses within the last 30 days or polymethylmethacrylate lenses within the last 3 months.
  • The patient must not be a current successful daily wear user of lotrafilcon A lenses. They may have tried lotrafilcon A lenses in the past, but must not have successfully worn these lenses for daily wear within the last 12 months.
  • The patient has an autoimmune disease (except for Hashimoto's Thyroiditis), immunocompromising disease, connective tissue disease, atopic dermatitis, insulin dependent diabetes, or any other systemic disease that in the investigator's opinion will affect ocular health.
  • The patient is taking chronic systemic medications such as corticosteroids, antimetabolites, or non-steroidal anti-inflammatory agents or any other medication that in the investigator's opinion will affect ocular physiology or study participation.
  • The patient has any ocular disease or condition such as aphakia, corneal dystrophies, corneal edema, external ocular infection, iritis, or had any anterior segment surgery.
  • The patient is taking any ocular medications. If a patient was previously taking any ocular medications, the medications must have been discontinued at least 2 weeks prior to enrollment.
  • The patient must have less than or equal to grade 2 on any of the slit lamp observations of: upper tarsal papilla, corneal staining, corneal neovascularization, conjunctival injection, and lid erythema or scales. Slit lamp findings higher than grade 2 bias the patient toward an adverse event and it may be difficult to detect true change related to contact lens use.
  • The patient is pregnant.

About this study

Official title: Infiltrative Events During Silicone Hydrogel Daily Contact Lens (Daily Wear Corneal Infiltrative Event (DWCIE) Study)

This DWCIE Study is a prospective cohort study of patients fit to the FDA approved and marketed lotrafilcon A (Ciba Vision, Air Optix Night \& Day Aqua) soft contact lenses for daily wear (DW) with monthly disposal. 218 healthy myopic (nearsighted) or hyperopic (farsighted) patients with minimal or no astigmatism and no contraindications to DW lens use will be followed for 1 year. The primary outcome is the risk of development of a corneal inflammatory event (CIE) as defined by slit lamp findings and patient symptoms. The main exposure of interest is microbial contamination of study lenses.

Being tested
lotrafilcon A contact lenses, Renu Multiplus, Clear Care
Medical subject headings
Myopia, Hyperopia

What is being measured

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

  1. Number of Participants Developing a Corneal Inflammatory Event (CIE)

    Raw number of participants in each solution arm developing CIE over 12 month follow-up period

    Measured: up to 1 year

Secondary outcomes (5)
  1. Number of Participants With CIE Stratified by Microbial Bioburden on Lenses

    Microbial bioburden on lenses was determined with predetermined cutoffs to identify substantial bioburden as high levels of normal flora or presence of pathogenic abnormal flora on lenses

    Measured: up to 1 year

  2. Number of Participants With CIE Based Stratified by Presence or Absence of Corneal Staining Induced by Solution Use.

    Presumed solution induced corneal staining was defined as diffuse punctate fluorescein staining of at least 15% surface area in at least 4 of 5 zones

    Measured: up to 1 year

  3. Number of Participants With CIE Stratified by Microbial Bioburden on Lens Cases

    Microbial bioburden within lens storage cases was determined with predetermined cutoffs to identify substantial bioburden as high levels of normal flora or presence of pathogenic abnormal flora

    Measured: up to 1 year

  4. Number of Participants With CIE Stratified by Overall Microbial Bioburden on Lid Margins

    Microbial bioburden on lid margins was determined with predetermined cutoffs to identify substantial bioburden as high levels of normal flora or presence of pathogenic abnormal flora on lids

    Measured: up to 1 year

  5. Number of Participants With CIE Stratified by CNS Microbial Bioburden on Lid Margins

    Microbial bioburden with coagulase negative staphylococci (CNS) on lid margins was determined with predetermined cutoffs to identify substantial bioburden as high levels of normal CNS flora on lids

    Measured: up to 1 year

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing lotrafilcon A contact lenses, Renu Multiplus and Clear Care in people with Myopia and Hyperopia, run by University Hospitals Cleveland Medical Center at 1 site in United States.

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 6 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 Mar 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 10 Mar 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?

Number of Participants Developing a Corneal Inflammatory Event (CIE) (time frame: up to 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00937105, which also lists 2 linked publications.

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 Mar 2014; AzTrials last refreshed its copy on 1 Nov 2026.
