1.8 mm切口超声乳化联合小梁切除术治疗慢性闭角型青光眼的临床效果观察

目的：观察1.8 mm切口超声乳化联合小梁切除术治疗慢性闭角型青光眼的临床效果。方法选择2012年1月～2013年12月本院眼科收治的90例慢性闭角型青光眼患者，将患者按照数字列表法随机分为观察组和对照组。观察组45例患者45眼采用1.8 mm切口超声乳化联合小梁切除术治疗，对照组45例45眼采用常规切口超声乳化联合小梁切除术治疗，比较两组患者术前、术后的视力、散光度、眼压和并发症。结果两组的术后视力均较术前明显改善，差异有统计学意义（P〈0.05），观察组术后1周、1个月、3个月的视力较对照组改善明显，差异有统计学意义（P〈0.05）；观察组的术后散光程度较对照组低，恢复快，差异有统计学意义（P〈0.05）；两组患者的术后眼压（IOP）较术前明显降低，差异有统计学意义（P〈0.05）；观察组的术后并发症发生率较对照组低，差异有统计学意义（P〈0.05）。结论1.8 mm切口超声乳化联合小梁切除术治疗慢性闭角型青光眼的效果显著，并发症发生率低。

Clinical effect observation of 1.8 mm incision phacoemulsification com-bined with trabeculectomy in treatment of chronic angle-closure glaucoma

Objective To observe the clinical effect of 1.8 mm incision phacoemulsification combined with trabeculectomy in treatment of chronic angle-closure glaucoma. Methods 90 patients with chronic angle-closure glaucoma treated in department of ophthalmology in our hospital from January 2012 to December 2013 were randomly divided into the observation group and the control group according to digital list method,45 eyes of 45 cases of patients in the observation group were treated by 1.8 mm incision phacoemulsification combined with trabeculectomy while 45 eyes of 45 cases of patients in the control group were treated by the conventional incision phacoemulsification combined with tra-beculectomy.Visual acuity,astigmatism,intraocular pressure before and after surgery and complications in the two groups were compared. Results The visual acuity of the two groups were significantly improved after surgery than before surgery,the difference was statistically significant （P〈0.05）,the visual acuity of the observation group was improved significantly after one week,one month,three months surgery than the control group,the difference was statistically significant （P〈0.05）;the degree of astigmatism of the observation group was lower than that in control group and recovery was quick,the difference was statistically significant （P〈0.05）;the postoperative IOP of the two groups was significantly lower than before surgery,the difference was statistically significant （P〈0.05）;the incidence rate of postoperative complications of the observation group was lower than those in the control group,the difference was statistically significant （P〈0.05）. Conclusion 1.8 mm incision phacoemulsification combined with trabeculectomy has a significant effect in treatment of chronic angle-closure glaucoma,with lower complication incidence rate.
