入选标准

  • •Students of grade 1-4 in the participating schools;
  • •Students' eyes have no myopia, that is the cycloplegic spherical equivalent(SE) >-0.50D, and at least one eye accords with the pre-myopic state, that is -0.50D <cycloplegic SE≤0.50D;
  • •Students whose mother and/or father are in myopia status (SE < -3.0D for either of eyes);
  • •Students whose parents sign informed consent and agree to let their kids participate in baseline screen and follow-up examinations and surveys.

排除标准

  • •Students whose parents do not sign informed consent;
  • •Students who have strabismus and/or other binocular vision abnormality;
  • •Students who have other eye diseases and/or systematic diseases;
  • •Students who have DC <=-1.5D;
  • •Students whose difference of SE between the two eyes >=1.5D;
  • •Students who meet the standards with which investigators and study physicians think it is not appropriate to enroll.

研究组 & 干预措施

Intervention

Experimental

Red light irradiation was conducted at school from Monday to Friday and at home everyday in summer and winter holiday twice a day for 3 minutes per time, with an interval of 4 hours

干预措施: LLLT(Low Level Laser Therapy) (Device)

Control

No Intervention

No intervention

结局指标

主要结局

One-year cumulative incidence of myopia (%) in the intervention group and the control group.

时间窗: 1 year

Myopia is defined as the cycloplegic spherical equivalent of either eye ≤-0.5D

次要结局

  • The progress of spherical equivalent(SE,D) of children in intervention group and control group.(1 year)
  • The progress of axial length of children in intervention group and control group.(1 year)
  • The progress of choroidal thickness in children in pre-myopia state in intervention group and control group.(1 year)
  • The change of uncorrected visual acuity (UCVA) of children in intervention group and control group.(1 year)
