Parameters	MPE (D)	Range of PE (D)	SD (D)	MAE (D)	MedAE (D)	Percentage of eyes within the ranges (%)
			SD (D)	MAE (D)	MedAE (D)	± 0.25 D	± 0.5 D	± 0.75 D
NT-ICL lens sphere	0.016	− 1.25 to 1.50	0.981	0.347	0.25	59.50	85.95	94.21
TICL lens sphere	− 0.729^a	3.25 to 2.50	1.420	1.221	1.00	23.98	33.16	45.41

PE = prediction error; MPE = mean prediction error; MAE = mean absolute error, MedAE = median absolute error; SD = standard deviation; D = diopters
The disparity between the recommended power and implanted lens power of NT-ICL did not differ significantly from zero, while that of TICL was lower with − 0.729 D than the implanted power. The recommended lens sphere deviated from the implanted lens sphere by < 0.25 D (one step provided by the manufacturer) in 56.92% of NT-ICL cases and < 0.50 D (one step provided by the manufacturer) in 32.20% of the time in TICL cases
^aStatistically significant difference from zero (P < 0.05)
