摘　　要：目的探讨梯形透明角膜切口在晶状体超声乳化术患者治疗中的临床效果。方法选取行晶状体超声乳化术的患者57例(68眼)作为研究对象,采用随机数字表法将患者分为常规切口组和梯形切口组。常规切口组28例(34眼),男15眼,女19眼,年龄41~82(65.0±10.1)岁;梯形切口组29例(34眼),男21眼,女13眼,年龄46~87(66.0±11.1)岁。两组患者均接受白内障超声乳化吸出联合人工晶状体植入术,常规切口组采用3.0 mm透明角膜切口,梯形切口组为改进的梯形透明角膜切口。比较两组患者术后裸眼视力、眼压及角膜散光度以及术中及术后并发症发生情况。结果术后1周及3个月梯形切口组患者裸眼视力均优于常规切口组,差异均有统计学意义(均为P<0.05);术后1周、1个月及3个月两组患者眼压及角膜散光度差异均无统计学意义(均为P>0.05)。术中常规切口组患者出现前房塌陷的眼数以及需要水密切口的眼数均大于梯形切口组,差异均有统计学意义(均为P<0.05);术后常规切口组患者出现切口水肿、切口哆开的眼数均大于梯形切口组,差异均有统计学意义(均为P<0.05)。术中常规切口组因前房变浅出现人工晶状体移位18眼,水密切口前房形成后人工晶状体位置正常;水密时2眼发生虹膜脱出切口嵌顿、3眼发生人工晶状体囊袋内旋转或囊口嵌顿。术中梯形切口组患者术毕3眼发生前房变浅,使用水密切口形成前房;无人工晶状体前囊口嵌顿、移位或虹膜脱出等情况。结论改良的梯形透明角膜切口可以在保证白内障患者术中前房稳定性的同时有效防止因术中前房塌陷而导致的人工晶状体移位,也能减少冲洗针头水密切口引起的相关并发症,使患者尽早恢复视力。Objective To explore the clinical effect of a trapezoidal transparent corneal incision during phacoemulsification.Methods A total of 57 patients(68 eyes)undergoing phacoemulsification were selected and divided into a conventional incision group and a trapezoidal incision group using a random number table method.There were 28 patients(34 eyes)in the conventional incision group,including 15 eyes(males)and 19 eyes(females),with an age range of 41-82(65.0±10.1)years;and there were 29 patients(34 eyes)in the trapezoidal incision group,including 21 eyes(males)and 13 eyes(females),with an age range of 46-87(66.0±11.1)years.All patients underwent cataract phacoemulsification combined with intraocular lens(IOL)implantation.A 3.0 mm transparent corneal incision was made for patients in the conventional incision group,while an improved trapezoidal transparent corneal incision was made for patients in the trapezoidal incision group.The uncorrected visual acuity,intraocular pressure,corneal astigmatism,and incidence of intraoperative and postoperative complications were compared between the two groups.Results The uncorrected visual acuity of patients in the trapezoidal incision group was better than that of patients in the conventional incision group at 1 week and 3 months after surgery,and the differences were statistically significant(both P<0.05).There was no statistically significant difference in intraocular pressure and corneal astigmatism between the two groups of patients at 1 week,1 month,and 3 months after surgery(all P>0.05).The number of eyes with anterior chamber collapse and the number of eyes requiring a watertight incision in the conventional incision group were greater than those in the trapezoidal incision group during surgery,and the differences were statistically significant(both P<0.05).The number of eyes with incision edema and the number of eyes with incision gap in the conventional incision group were greater than those in the trapezoidal incision group after surgery,and the differences were statisti
