What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • MiSight mutifocal soft contact lensDevice

    Subjects will wear MiSight™ multifocal soft contact lenses for 1 month.

  • Proclear 1 Day soft contact lensDevice

    Proclear™ 1 Day soft contact lens will be worn for baseline evaluation.

What is being measured

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

  1. Change in the contrast sensitivity visual function (CSF) relative to baseline at 1 month

    Measured: Proclear baseline;VMisight baseline; 1 week; 1month

Secondary outcomes (3)
  1. Patients' subjective acceptability to multifocal soft contact lens

    The patients will be asked to complete questionnaires at each visit regarding vision, lens comfort, the difficulty of lens insert and removal, etc. of the multifocal contact lens.

    Measured: Proclear baseline; Misight baseline; 1 week; 1month

  2. Doctors' clinical evaluation to multifocal soft contact lens

    The doctors will be asked to complete questionnaires regarding the difficulty of fitting procedure and general impression of the multifocal contact lens.

    Measured: Proclear baseline; Misight baseline; 1 week; 1month

  3. Change in the contact lens corrected visual acuity relative to baseline

    Patients will wear contact lens when they are tested

    Measured: Proclear baseline;Misight baseline;1 week;1month

Questions about this trial

What is this clinical trial studying?

A study testing MiSight mutifocal soft contact lens and Proclear 1 Day soft contact lens in people with Myopia, run by Zhongshan Ophthalmic Center, Sun Yat-sen University at 1 site in China.

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 20 inclusion and 12 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: status not confirmed, as of the sponsor's last update on 28 Dec 2022. 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 China. 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?

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?

Change in the contrast sensitivity visual function (CSF) relative to baseline at 1 month (time frame: Proclear baseline;VMisight baseline; 1 week; 1month). 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 28 Dec 2022; AzTrials last refreshed its copy on 7 Nov 2026.
