Arms of the Study
Arm 1
Arm 2
Arm Type
Experimental
Active Comparator
Arm Label
Red Light Intervention
Low concentration atropine
Arm Description
Repeated Low-Level Red-Light Therapy
0.01% atropine
Outcomes
Primary Outcome Measures
Changes of axial length
AL was measured as the distance from the anterior corneal surface to the retinal pigment epithelium (RPE) using IOLMaster
Secondary Outcome Measures
Change of spherical equivalent
Spherical equivalent as measured by cycloplegia autorefraction
Change of choroidal thickness
Choroidal thickness will be measured using SS-OCT
Change of uncorrected visual acuity
Uncorrected visual acuity (UCVA) will be measured using a mounted and illuminated E chart of the Early Treatment Diabetic Retinopathy study (ETDRS) charts.
