Detailed description

This was a randomized clinical trial. Children aged 8 to 10 years with a spherical equivalent error (SER) ranging from -1 to -1.5 diopters (D) were enrolled, and were randomly allocated to the following treatment group: RL, DIT, RL plus DIT, and control in a 1:1:1:1 ratio. The primary outcomes were one-year change in SER and axial length.

Conditions

• Myopia
