About this study

This study will evaluate the ability of toric multifocal contact lens to reduce the change of myopia progression in children (aged 8-12) with myopic astigmatism.

Read the detailed description

The purpose of this study is to assess if a center distance toric multifocal contact lenses can slow the amount of change of myopia progression in children with myopia plus astigmatism. Multifocal contact lenses have been theorized to influence the peripheral optics of the eye such that they slow the rate of myopia progression in nearsighted children. This outcome is yet to be evaluated in children with myopia plus astigmatism.The secondary outcome is to measure the change in peripheral optics caused by the contact lens. This information is key to understanding the mechanism of multifocal contact lens optics on the eye. Ultimately this information would be used to create a software that can estimate the effect of multifocal contact lenses on the peripheral optics of the child's eye. This software can potentially be used by practitioners worldwide to better customize multifocal contact lenses to slow myopia progression.

What is being measured

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

  1. Refractive error progression

    Refractive error measured by cycloplegic autorefraction in both eyes, will be measured at baseline and at one year to assess the difference in spherical component of the refractive error between the treatment group (multifocal toric soft contact lens) and the control group (toric soft contact lens)

    Measured: 1 years

  2. Axial length

    Change in axial length as measured by non-contact axial length both eyes, will be measured at baseline and at one year to assess the difference in change in axial length between the treatment group (multifocal toric soft contact lens) and the control group (toric soft contact lens)

    Measured: 1 years

Questions about this trial

What is this clinical trial studying?

A study testing Intelliwave multifocal, toric, soft contact lens and Intelliwave toric, soft contact lens in people with Refractive Errors and Myopia, run by University of Alabama at Birmingham.

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 4 inclusion and 3 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: withdrawn, as of the sponsor's last update on 9 Nov 2020. Status can change between updates, so confirm with the study contact before making plans.

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 withdrawn before enrolling participants, so there are no results.

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?

Refractive error progression (time frame: 1 years). 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 9 Nov 2020.
