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 18 to 40 years
  • All sexes
  • Healthy volunteers accepted
  • Adult

Who may be able to join

  • Participants must be correctable through spherocylindrical refraction to 42 letters (0.1 logMAR) or better (distance, high contrast) in each eye.
  • Participants must be adapted lens wearers and wear a lens in each eye; each lens must be of the same manufacturer and brand.
  • Participants must be myopic and require lens correction from -0.50 diopters (D) to 6.00 D in each eye.
  • Participants must have clear central corneas and be free of any anterior segment disorders.
  • Participants must agree to wear their lenses on an extended wear basis (6 nights/7 days) for the duration of the study.

Who cannot join

  • Participants who have worn gas permeable (GP) contact lenses within the last 30 days or who have worn polymethylmethacrylate (PMMA) lenses within the last three months.
  • Participants with an active ocular disease or who are using any ocular medication.
  • Participants with any systemic disease currently affecting ocular health or which in the Investigator's opinion may have an effect on ocular health during the course of the study.
  • Participants using any systemic medications that will, in the Investigator's opinion, affect ocular physiology or lens performance.
  • Participants who are not correctable to 42 letters (0.1 logMAR) in each eye with soft spherical contact lenses.
  • Participants who currently wear monovision, multifocal, or toric contact lenses.

About this study

Official title: A Study to Evaluate the Safety and Effectiveness of a Silicone Hydrogel Soft Contact Lens When Worn on a 7-Day Extended Wear Basis

The objective of this study is to evaluate the safety and effectiveness of the Bausch + Lomb samfilcon A soft (hydrophilic) contact lens, a new silicone hydrogel contact lens, compared to the Bausch + Lomb PureVision® soft contact lens when worn for 7-day extended wear by adapted soft contact lens wearers.

Read the detailed description

Approximately 816 participants (1,632 eyes) will be enrolled in this 12-month randomized, parallel, Investigator/Sponsor masked study at approximately 35 investigative sites in the US.

At the Screening/Dispensing Visit, approximately one-half of the participants will be randomized to receive Bausch + Lomb investigational samfilcon A soft contact lenses (Test) and approximately one-half of the subjects will be randomized to receive Bausch + Lomb PureVision soft contact lenses (Control). Both groups will wear the assigned lenses bilaterally on a 7-day extended wear basis throughout the 12 month study. The lenses are to be worn overnight for up to six consecutive nights per week. The lenses are to be removed, cleaned and disinfected on the seventh night and re-inserted the following morning. The lenses will be replaced with new lenses at the beginning of each month. Lenses will be provided at the Screening/Dispensing, 3-Month, 6-Month and 9-Month Follow-Up visits to maintain a monthly replacement schedule. Participants will also be required to complete a paper diary.

What is being measured

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

  1. High Contrast Visual Acuity

    For determination of high contrast visual acuity (VA), the participant was seated at the photoropter so that the distance from the participant's eyes to the logMAR chart was 6.5 feet (2.0 meters). The chart was at eye level for each participant. The logMAR charts had two alternative letter sequences from 28 letters (0.3 logMAR) to 62 letters (-0.3 logMAR). The visual acuity was measured through the phoropter using the distance refractive correction with the addition of +0.50 Diopter to compensate for the reduced test distance of 6.5 feet (2.0 meters). A scoring sheet for each eye was provided to keep track of the letters correctly identified by the participants. Scores were recorded as the numbers of letters correctly identified in the eye examination. VA was converted to the Log10 of the Minimum Angle of Resolution (logMAR) by using the score (number of letters).

    Measured: Month 12

  2. Number of Participants With Adverse Events

    An AE was defined as any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. Serious adverse events were defined as those events that resulted in, or had the potential to cause, either permanent impairment of an ocular function or damage to an ocular structure, and might necessitate medical or surgical intervention. A summary of other non-serious AEs and all serious AEs, regardless of causality is located in reported AE section.

    Measured: Baseline up to Month 12

Questions about this trial

What is this clinical trial studying?

A study testing Bausch + Lomb Samfilcon A Soft Contact Lens and Bausch + Lomb Pure Vision Soft Contact Lens in people with Myopia, run by Bausch Health Americas, Inc. 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 5 inclusion and 6 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 23 Dec 2019. 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.

Are results available for this study?

Yes. Results are posted in the registry (first posted 10 Dec 2019). 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?

High Contrast Visual Acuity (time frame: Month 12). 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 23 Dec 2019.
