About this study

Official title: Evaluation of Ophthalmic Lenses for Myopia Management

Evaluation of the efficacy in decreasing myopia progression of the proposed ophthalmic lens prototypes.

Read the detailed description

A prospective, double-blind, randomized clinical trial (RCT) to analyze the effect of a new ophthalmic lens prototype on myopia progression. The follow-up period to evaluate the efficacy of the lens will be 3 years including a total of 5 visits.

The sample will consist of a group of 92 myopic children who will be randomly assigned to one of the treatment groups:

  • Control group who will receive standard monofocal lenses.
  • Treatment group who will wear a prototype lens based on peripheral positive defocus.

Study groupRoleWhat they receive
Axial lenght increaseExperimentalChildren aged 5 to 12 with myopia up to -0.50 D, astigmatism and anisometropia under 1.50 D, and corrected visual acuity over 20/20 will be randomized to either the control group or treatment group. The myopia progression was evaluated by measuring axial length (AL) growth (IOL Master; Zeiss) over a period of one year.
Receives: Other: Myopia control lens

What is being measured

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

  1. Axial Lenght Increase

    Axial length was measured with the IOL Master® optical biometer (Carl Zeiss Meditec, Jena, Germany) and axial length growth was calculated by subtracting the axial length measurement after one year of treatment and the axial length at the initial visit.

    Measured: 5 minutes

Questions about this trial

What is this clinical trial studying?

A study of Myopia, run by Indizen Optical Technologies, S.L.U. at 1 site in Spain.

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 5 inclusion and 4 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: finished, as of the sponsor's last update on 10 Jun 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 Spain. 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?

Yes. Results are posted in the registry (first posted 10 Jun 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Axial Lenght Increase (time frame: 5 minutes). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05250206, which also lists 3 linked publications.

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 10 Jun 2025; AzTrials last refreshed its copy on 8 Nov 2026.
