目的：观察1．8 mm同轴微切口白内障超声乳化术对角膜散光的影响，并与传统3．2 mm小切口白内障超声乳化手术进行比较。 　　方法：年龄相关性白内障患者160例168眼，年龄50～83岁，晶状体混浊分级为Ⅱ～Ⅴ级，随机分为两组，每组84眼，分别行1．8mm同轴微切口（微切口组）和传统3．2mm小切口（常规组）白内障超声乳化手术，术后第1 d；1 wk；1 mo观察随访，记录裸眼视力及散光改变，采用χ2检验和t检验对所得数据进行分析。 　　结果：术后第1d；1wk；1mo微切口组裸眼视力≥0．5者分别占79％，83％，94％，常规组裸眼视力≥0．5者分别占46％，64％，85％，两组差异有统计学意义（ P＜0．05）；术后第1d，微切口组平均角膜散光为0．75±0．45D，常规组角膜散光为1．12±0．55D，两组比较有显著性差异（ P＜0.01），术后1wk和1mo，微切口组平均角膜散光分别为0．76±0．40D和0．65±0．35D，常规组平均角膜散光为1.05±0．53D和0．85±0．43D，两组比较有统计学意义（ P＜0.05）。 　　结论：1．8 mm同轴微切口白内障超声乳化术较常规超声乳化术，术源性角膜散光更小，术后视力恢复更快。

AIM: To observe the effect of 1.8mm coaxial micro-incision cataract phacoemulsification on corneal astigmatism, and compared with the effect of traditional 3.2mm small incision cataract phacoemulsification . METHODS: Totally 160 patients ( 168 eyes ) with age-related cataract were selected, whose age from 50 to 83 years old.Their lens opacities classification was Ⅱ-Ⅴgrade.Two groups were divided randomly and each group included 84 eyes.They performed 1.8mm coaxial micro-incision ( micro-vision group ) and traditional 3.2mm small incision ( control group ) of cataract phacoemulsification respectively. After 1d, 1wk, 1mo follow-up, their naked vision and astigmatism changes were recorded.The χ2-test and t-test was used for the statistical analysis. RESULTS: After 1d, 1wk, 1mo of the micro-incision surgery, naked vision ≥0.5 of the patients were 79%, 83% and 94% respectively. In control group, naked vision ≥0.5 were 46%, 64% and 85% respecticvely. There was significant difference between the two groups (P<0.05).The average corneal astigmatism of micro-incision group was 0.75 ±0.45D on 1d after surgery, and that of the control group was 1.12 ±0.55D.There were significant difference between two groups ( P<0.01 ). After 1wk and 1mo, the average corneal astigmatism of micro incision group was 0.76 ±0.40D and 0.65 ±0.35D, and the average corneal astigmatism of control group was 1.05±0.53D and 0.85 ±0.43D.The two groups were statistically significant (P<0.05). CONCUSION: The corneal astigmatism of 1.8mm coaxial micro-incision cataract phacoemulsification was smaller than that of the conventional phacoemulsification and visual recovery was also better after surgery.
