Average Central Keratometric Power (D) at Baseline and 1 Year of Age for Treated and Fellow Eyes of 52 Patients Treated with a Contact Lens

Follow-up Visit	Treated Eye*	Fellow Eye*	Difference*	p-value**	95% CI†
Baseline	46.3 (2.8)	45.4 (1.8)	0.9 (2.3)	0.009	0.2–1.5
Age 1 Year	44.6 (2.3)	43.4 (1.5)	1.2 (2.5)	0.001	0.5–1.9
Change Per Month§	−0.2 (0.2)	−0.2 (0.2)	0.02 (0.3)	0.56	−0.06–0.1

^*Values are mean (standard deviation)

^**The p-value for the paired t test comparing the means of the treated and fellow eyes.

^†The 95% Confidence Interval for the difference between the means of the treated and fellow eyes.

^§The change was calculated as (Follow-up – Baseline) and therefore negative values indicate a decrease in average central keratometric power.
