The 1-week visit occurs within ± 3 days of one week; the 3-week visit occurs within 1 week of the three-week date; all subsequent visits occur at six-month intervals ± 30 days.
cycloplegic measures; X (M) = wearing manifest refraction in trial frame; X (CL) = wearing habitual contact lens; OD = right eye; OS = left eye; OU = both eyes.
