- Paired Comparison Before and After Cycloplegia [ Time Frame: 2020.2.3 ]The cycloplegia-induced differences of parameters was defined as: the post-cycloplegic value minus the pre-cycloplegic value.
- Evaluated the effect of age on the TM/SC morphologies [ Time Frame: 2020.2.3 ]The age-related variations of TM/SC parameters from four age groups were compared.
- Evaluated the effect of age on the ocular biometric data [ Time Frame: 2020.2.3 ]The age-related variations of ocular biometric data such as axial length (AL), lens thickness (LT), and anterior chamber depth (ACD) from four age groups were compared.
