Observations
LENS, CYCLOPLEGIA, ACD
To compare the biological parameters of the eyeballs before and after wearing lens, cycloplegia was performed for the patients using cyclopentanone eye drops (1%) by examining whether the light reflection still existed. It was necessary to add eye drops again until the light reflection disappeared. Then the data were measured and recorded. BCVA, AL, SER, CCT, ACD and CLT were measured and recorded before wearing glasses, after wearing glasses for 6 months and 12 months, and after withdrawal for 1 month.
