Trial summary

In this study, the direct effect of the MiSight contact lens (Cooper Vision), a daily disposable contact lens recently approved in Germany for the treatment of myopia, will be investigated. The aim of this study is to demonstrate an increase in choroidal thickness due to the myopic defocus induced by the contact lens. Read more about this study

About this study

In this study, the direct effect of the MiSight contact lens (Cooper Vision), a daily disposable contact lens recently approved in Germany for the treatment of myopia, will be investigated. The aim of this study is to demonstrate an increase in choroidal thickness due to the myopic defocus induced by the contact lens. The increase in choroidal thickness after 30 minutes of exposure to the myopic defocus induced by the contact lens will be demonstrated by measuring the subfoveal and macular choroidal thickness.

Read the detailed description

The increasing incidence of short-sightedness (myopia) worldwide has led to the development of various therapies to control axial length myopia. The latest developments include contact lenses to inhibit the growth of the bulb length, which should influence the growth of the eye in childhood and adolescence by inducing a myopic defocus in the periphery of the retina.

In this study, the direct effect of the MiSight contact lens (Cooper Vision), a daily disposable contact lens recently approved in Germany for the treatment of myopia, will be investigated. The aim of this study is to demonstrate an increase in choroidal thickness due to the myopic defocus induced by the contact lens. The increase in choroidal thickness after 30 minutes of exposure to the myopic defocus induced by the contact lens will be demonstrated by measuring the subfoveal and macular choroidal thickness. In addition, the influence of accommodation will be investigated by measuring the choroidal thickness after 30 minutes of activity at near and far distance. One eye of each of 8 healthy subjects with myopic refraction from -0.5 diopters in the spherical equivalent will be included, with laterality (right/left) being randomized. The choroidal thickness is measured using optical coherence tomography (OCT), which is standard in clinical routine. The examination is non-invasive and is carried out at three points in time: The baseline measurement is carried out before inserting the contact lens, then after 30 minutes of exposure and near focusing. A further measurement is carried out within a week after a further 30 minutes of exposure and distance focusing, so that the results are not distorted by the previous near work. In addition, the axial length is determined at each of the 3 measurement times using optical biometry.

Questions about this trial

What is this clinical trial studying?

A study of Myopia, run by University Hospital Augsburg at 1 site in Germany.

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 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: enrolling by invitation, as of the sponsor's last update on 26 Mar 2025. 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 Germany. 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?

Choroidal thickness (time frame: 30 minutes). 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 26 Mar 2025.
