About this study

Official title: Effect of Using Myopia Prediction Algorithm on Myopia School-aged Children's Eye Refraction in China: a Multi-center Randomized Control Trial

In this study, the investigators aim to perform a prospective, randomized controlled study to compare the myopia development between myopia children using myopia prediction algorithm and myopia children without using myopia prediction algorithm

Read the detailed description

The investigators propose to enroll myopia children aged 8-10 in China. Children will be given examinations of visual acuity, eye refraction and biometrics, and be assigned to two groups: participants in group A use myopia prediction algorithm to predict myopia development, while in Group B, the participants do not use myopia prediction algorithm to predict myopia development. The visual acuity, eye refraction and biometrics will be investigated over the one-year follow-up period, aiming at comparison of actual myopia development between the two groups

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Myopia prediction algorithmOther

    Candidate predictors included age at examination, SER, and annual progression rate. Using these predictors, the algorithm will be used to predict SER at 3 years.

Study groupRoleWhat they receive
Using myopia prediction algorithmExperimentalAfter examination of visual acuity, eye refraction and biometrics, the examination results are shown to the children. Meanwhile, myopia prediction algorithm will be used to predict SER at 3 years.
Receives: Other: Myopia prediction algorithm
Not using myopia prediction algorithmNo interventionAfter examination of visual acuity, eye refraction and biometrics, the examination results are shown to the children.

What is being measured

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

  1. Incidence of SER development of at least -1.0 dioptres (D)

    SER: spherical equivalent refraction, sphere + ½ 360 cylinder; SER development of at least -1.0 dioptres: SER2 - SER1≤-0.5D; SER1: SER at baseline; SER2: SER up to 2 year

    Measured: up to 2 year

  2. Incidence of SER development of at least -0.5 dioptres (D)

    SER: spherical equivalent refraction, sphere + ½ 360 cylinder; SER development of at least -0.5 dioptres: SER2 - SER1≤-0.5D; SER1: SER at baseline; SER2: SER up to 1 year

    Measured: up to 1 year

Questions about this trial

What is this clinical trial studying?

A study testing Myopia prediction algorithm in people with Myopia, run by Sun Yat-sen University at 1 site in China.

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 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: status not confirmed, as of the sponsor's last update on 7 Aug 2019. 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 China. 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Yahan Yang (+8615521013933, yah.yang39@hotmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence of SER development of at least -1.0 dioptres (D) (time frame: up to 2 year). 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 7 Aug 2019.
