Lag of the contact lens, which is the difference in distance from the limbus to contact lens edge between when the subject fixates in various gazes and the same lens location while the subject fixates in primary gaze of habitual and multifocal contact lenses. For example, decentration = distance from limbus to contact lens edge of the inferior contact lens while looking superiorly – distance from limbus to contact lens edge of the inferior contact lens while looking in primary gaze.

Average decentration ± SD	Habitual	p-value	Multifocal	p-value
Inferior - primary	0.52 ± 0.29	< 0.001	0.49 ± 0.28	< 0.001
Superior - primary	0.19 ± 0.34	= 0.01	0.24 ± 0.36	= 0.008
Nasal - primary	0.56 ± 0.23	< 0.001	0.58 ± 0.20	< 0.001
Temporal - primary	0.43 ± 0.24	< 0.001	0.35 ± 0.21	< 0.001
