The EYERISING Study

November 3, 2026 updated by: University of Wisconsin, Madison

Repeated Low-level Red Light for Myopia Progression Study: An International, Multicenter, Multiethnic, Randomized Controlled Trial, IPOSC Study

The purpose of this clinical trial is to see if and how well Repeated Low-Level Red Light (RLRL) therapy works to control myopia over 12 months. The main question it aims to answer is:

  • Can RLRL therapy help slow down the worsening of myopia?

Participants will use a red-light therapy investigational device at home, 5 days a week for 12 months.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

6 years to 12 years (Child)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Exclusion Criteria:

  • A subject who is born female and who is currently menstruating or has begun menstruation (menarche).

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Red light therapy

Participants will receive red light therapy
Device: Repeated Low-Level Red Light (RLRL) therapy

RLRL device emits low-level red-light with a wavelength of 650 ± 10 nm. The device provides light at a power of 2.00 ± 0.50 mW.
Placebo Comparator: Placebo

Participants will receive placebo therapy
Device: Placebo Device

Placebo device will match the RLRL in appearance but will not emit light.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in cycloplegic spherical equivalent refraction (SER)
Time Frame: Baseline, 4 months, 8 months, 12 months

SER will be measured using an autorefractometer after eye drops are given to temporarily relax the eye's focusing muscles. SER, measured in diopters (D), represents the amount of nearsightedness and will be used to measure the change in myopia from baseline.
Baseline, 4 months, 8 months, 12 months
Change in axial length (AL)
Time Frame: Baseline, 4 months, 8 months, 12 months

AL will be measured using the IOLMaster and reported in millimeters (mm). Change in AL from baseline will be used to assess ocular growth/myopia progression.
Baseline, 4 months, 8 months, 12 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame

Time Frame: Baseline, 4 months, 8 months, 12 months
Baseline, 4 months, 8 months, 12 months
