Comparison of Model-Calculated Outputs of Ocular Refraction and Lens Power Before and After Modification of the T₂-n Calibration

	Regression Equation	R 2	P
Difference in ocular refraction (D)
Original*	–3.073 + 0.049 × age	0.325	<0.001
Modified	–0.162 – 0.007 × age	0.014	0.388
Lens power (D)
Original*	17.364 + 0.055 × age	0.210	<0.001
Modified*	22.353 – 0.041 × age	0.134	0.005

^*The results of the regression analysis were statistically significant.
