About this study
The purpose of this post-approval study is to confirm the effectiveness of the MiSight 1 Day lens in clinical practices within the US and to assess the stability of the myopia reduction over one-year post-treatment.
Read the detailed description
This study is a multicenter, parallel-group, controlled, double-masked (subject and investigator), randomized clinical trial with a total duration of four years.
Part 1 of this study will study the effectiveness of MiSight 1 Day in slowing myopia progression over three years in a US population. Subjects in Part 1 will wear MiSight 1 Day lenses or Proclear 1 day lenses.
Part 2 will study the stability of the effectiveness result over a one-year post-treatment period. All subjects in Part 2 will wear Proclear 1 day lenses. Subjects and investigators will remain masked from Part 1.

Questions about this trial
What is this clinical trial studying?
A study testing MiSight 1 Day and Proclear 1 day in people with Myopia, run by CooperVision, Inc. at 30 sites 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 15 inclusion and 22 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: under way, not looking for participants, as of the sponsor's last update on 8 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 30 sites 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?
This study is still under way. Results are not available in the source record yet.
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?
Mean difference in cycloplegic SERE change from baseline (time frame: 3 years). The study lists 4 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 8 Jul 2026.
