Change in the mean postoperative angles. The mean distance deviation, mean near deviation, and near-distance difference (mean ± SD, range) showed significant postoperative reductions (P < 0.01).

	Distance deviation (PD)	Near deviation (PD)	Near-distance difference (PD)
Before operation	32.4 ± 4.8 (25~40)	43.4 ± 3.2 (35~50)	11.0 ± 2.0 (10~15)
Postoperative 3 months	2.2 ± 3.8 (0~14)	3.1 ± 4.4 (0~16)	0.9 ± 1.6 (0~6)
Postoperative 6 months	2.0 ± 4.3 (−2~16)	3.4 ± 5.0 (−2~18)	1.4 ± 2.2 (0~8)

PD = prism diopters.
