efficacy
ACTIVE COMPARATORIncluding Primary outcome: changes in axial length of the eye. Secondary outcome: Equivalent spherical lens variation Other indicators: ① Changes in visual acuity with lenses, corrected visual acuity, and intraocular pressure.② Observation of changes in corneal thickness, anterior chamber depth, ciliary body thickness, and crystal thickness.Observation of fundus tissue structure of macula and peri-optic disc area. Observation of fundus choroidal/retinal thickness.Adherence index: frequency of device use.
safety
ACTIVE COMPARATORDescription of safety parameters: Adverse events, device defects during the test. Method and time selection for evaluation, recording, and analysis of safety parameters. Adverse events and device defects were recorded from the beginning of each subject's enrollment to the end of the group for evaluation. Safety indicators:① Incidence of allergic reactions.② Posterior image time more than 5 minutes.③ The decrease of near vision.④ The grade of side effects such as self-induced photophobia and blurred vision.⑤ Elevated intraocular pressure, headache, nausea, and vomiting, etc.
Interventions
Eyesing Instrument developed by Suzhou Industrial Park Zoguan Medical Equipment Co. and conventional optometry.
