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.

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; AzTrials last refreshed its copy on 7 Nov 2026.
