Effect of Spectacle Lenses with Highly Aspherical Lenslets on Binocular Vision and Accommodation in Myopic Children with and without Intermittent Exotropia

Table 5

Absolute differences in visual parameters between two lenses in IXT and visually normal groups.

	IXT group	Visually normal group	Difference (95% CI)	T value	Value
NPC (cm)	0.08 (0.50)	−0.11 (0.45)	0.18 (−0.12, 0.49)	1.22	0.23
Binocular AA (D)	−0.64 (2.04)	−0.11 (2.06)	−0.54 (−1.85, 0.78)	−0.83	0.41
Monocular AA (D)	−0.38 (1.41)	−0.19 (1.25)	−0.19 (−1.04, 0.66)	−0.45	0.66
AR (D)	0.02 (0.55)	0.20 (0.54)	−0.18 (−0.54, 0.19)	−0.98	0.33
AMF (D)	0.04 (0.02)	0.05 (0.04)	−0.01 (−0.03, 0.01)	−1.25	0.22

Data are presented as means (SDs). Absolute differences are defined as HAL—SVL. Abbreviations: IXT, intermittent exotropia; HAL, spectacle lenses designed with highly aspherical lenslets; SVL, single vision spectacle lenses; NPC, near point of convergence; AA, accommodative amplitude; AR, accommodative response; AMF, accommodative microfluctuation; D, diopters; PD, prism diopters.
