摘　　要：目的观察比较白内障超声乳化术1.8mm角膜切口与3.0mm角膜切口对角膜内皮和术源性散光的影响。方法根据不同术式将120例白内障患者随机分为1.8mm切口观察组与3.0mm切口对照组行预劈核超声乳化治疗,观察两组病例平均超声时间,平均超声能量,术前,第1d,1wk,1mo的视力、角膜散光变化、角膜内皮计数等情况。结果观察组和对照组有效超乳时间9.51±1.17,9.48±1.21及平均超乳能量(10.01±1.02)%(9.9±1.19)%比较差异均无统计学意义(P>0.05)。两组术前视力0.11±0.057,0.10±0.012比较无统计学差异(P>0.05),术后第1d两组视力0.376±0.071,0.319±0.14比较有统计学意义(P<0.05);术后1wk;1mo两组视力0.410±0.14,0.356±0.12,0.429±0.15,0.364±0.14比较有统计学意义(P<0.05)。平均角膜散光两组术前0.59±0.25,0.61±0.30比较无统计学意义(P>0.05),术后两组第1d(0.91±0.42,1.15±0.41),1wk(0.76±0.26,0.95±0.24)和1mo(0.66±0.23,0.74±0.25)比较有统计学差异(P<0.05)。角膜内皮计数两组术前2753.32±324.12,2645.36±321.45比较无统计学意义(P>0.05),术后第1d(2412.36±541.12,2397.62±204.21),1wk(2365.35±233.72,2351.36±248.63)和1mo(2298.37±251.89,2209.45±373.07),比较无统计学差异(P>0.05)。结论,1.8mm切口超声乳化术同传统3.0mm切口组比较,不导致超乳效率下降及更多的角膜内皮细胞的损伤,且术后医源性散光相较更小,术后视力更佳。Objective To observe and compare the effects of phacoemulsification with 1.8mm incision and 3.Omm conventional incision on corneal endothelium and intraoperative astigmatism.t.Methods A total of 120 cataract patients were randomly divided into 1.8mm incision observation group and 3.Omm incision control group for pre-split nucleus phacoemulsification.The mean ultrasound time and mean ultrasound energy of the two groups were observed,before operation,on the first day.Iwk;Visual acuity,changes of corneal astigmatism,corneal endothelium count,etc.Results There was no statistically significant difference(P>0.05)between the observation group and the control group in terms of ffective lactation time(9.51±1.17,9.48±1.21)and average lactation energy(10.01±1.02)%,(9.9±1.19)%.There was no statistically significant difference in preoperative visual acuity(0.11±0.057,0.10±0.012)between the two groups(P>0.05),but there was a statistically significant difference in visual acuity(0.376±0.071,0.319±0.14)between the two groups on the first day after surgery(P<0.05);1 week after surgery;There was statistically significant difference in visual acuity between the two groups(0.410±0.14,0.356±0.12,0.429±0.15,0.364±0.14).The average corneal astigmatism in both groups before surgery(0.59±0.25,0.61±0.30).There was no statistically significant difference(P>0.05)between the two groups on the 1st day after surgery(0.91±0.42,1.15±0.41).There was a statistically significant difference(P<0.05)between 1 week(0.76±0.26,0.95±0.24),and 1 month(0.66±0.23,0.74±0.25).There was no statistically significant difference in corneal endothelial count between the two groups before surgery(2753.32±324.12,2645.36±321.45)(P>0.05).0n the first day after surgery(2412.36±541.12,2397.62±204.21),1 week(2365.35±233.72,2351.36±248.63),and 1 month(2298.37±251.89,2209.45±373.07),there was no statistically significant difference(P>0.05).Conclusion Compared with the traditional 3.0mm incision group,the 1.8mm incision phacoemulsification group d
