摘　　要：目的 评价白内障撕囊口控制环的临床应用效果。方法 选取60例(60眼)年龄相关性白内障患者为研究对象,按照随机数字表法分为A组与B组,每组30例(30眼)。A组行常规连续环形撕囊白内障超声乳化+折叠式人工晶状体植入术, B组在白内障撕囊口控制环辅助下行连续环形撕囊白内障超声乳化+折叠式人工晶状体植入术。比较两组撕囊口合格率、人工晶状体轻度偏移情况、视力、眼压,以及术中和术后并发症发生情况。结果 两组均顺利完成连续环形撕囊。A组撕囊口合格24眼(80.0%), B组合格30眼(100.0%)。B组撕囊口合格率高于A组,差异有统计学意义(P<0.05)。两组术后1个月人工晶状体轻度偏移率比较差异无统计学意义(P>0.05)。两组术后1 d、1周视力>0.5占比比较,差异无统计学意义(P>0.05)。术前, A组眼压为(14.17±2.47)mm Hg(1 mm Hg=0.133 kPa), B组为(14.60±2.97)mm Hg;术后A组眼压为(15.37±3.59)mm Hg, B组为(15.63±3.05)mm Hg。手术前后两组眼压比较差异无统计学意义(P>0.05)。术中两组无一例发生前房出血、虹膜损伤及后囊膜破裂。术后两组无一例发生前房渗出,两组角膜水肿及前房闪辉发生率比较差异无统计学意义(P>0.05)。两组角膜水肿均在1周内消退。结论 白内障撕囊口控制环可明显提高撕囊口合格率,有助于手术顺利完成,使人工晶状体处于完美位置,并提高手术的安全性。Objective To evaluate the clinical effect of control ring for cataract capsulorhexis. Methods A total of 60 patients(60 eyes) with age-related cataract were studied, and the patients were divided into group A and group B according to the random numerical table, with 30 patients(30 eyes) in each group. Group A received conventional continuous curvilinear capsulorhexis phacoemulsification+foldable intraocular lens implantation, and group B received continuous curvilinear capsulorhexis phacoemulsification+foldable intraocular lens implantation under the assistance of the control ring for cataract capsulorhexis. The qualification rate of capsulorhexis, the slight deviation of intraocular lens, visual acuity, intraocular pressure, and the incidence of intraoperative and postoperative complications were compared between the two groups. Results Continuous curvilinear capsulorhexis was successfully completed in both groups. Group A qualified 24 eyes(80.0%) and group B qualified 30 eyes(100.0%). The qualification rate of capsulorhexis in group B was higher than that in group A, and the difference was statistically significant(P<0.05). At 1 month after surgery, there was no statistically significant difference in the slight deviation of IOL between the two groups(P>0.05). There was no statistically significant difference between the two groups when comparing the percentage of visual acuity >0.5 at 1 d and 1 week after surgery(P>0.05). Before surgery, IOP was(14.17±2.47) mm Hg(1 mm Hg=0.133 kPa) in group A and(14.60±2.97) mm Hg in group B;after surgery, IOP was(15.37±3.59) mm Hg in group A and(15.63±3.05) mm Hg in group B. The difference in IOP between the two groups before and after surgery was not statistically significant(P>0.05). None of the two groups had anterior chamber hemorrhage, iris injury or posterior capsule rupture during surgery. No anterior chamber exudation occurred in either group after surgery.There was no statistically significant difference in the incidence of corneal edema and anterior chamber flar
