方法：选择2012-01/2013-12期间我院所收治的高度近视眼合并白内障患者82例96眼，随机将患者分为对照组40例46眼和研究组42例50眼，对照组患者采用小切口囊外摘除术及人工晶状体植入术进行治疗。研究组患者采用超声乳化摘除及人工晶状体植入术进行治疗。比较分析两组患者治疗后裸眼视力、最佳矫正视力以及术后角膜水肿、后囊混浊、眼压升高等并发症的发生情况，同时对研究组患者术后眼底情况进行检查。

结果：与对照组患者相比，研究组患者治疗后，0.1≤裸眼视力<0.5，0.5≤裸眼视力<1.0及1.0≤裸眼视力≤1.5的比率均有所增高，但差异不具有统计学意义(P<0.05)。与对照组患者相比，研究组患者治疗后，0.1≤最佳矫正视力<0.5的比率明显降低，仅为28%，0.5≤最佳矫正视力<1.0及1.0≤最佳矫正视力≤1.5明显增高，可达58%和14%，差异均具有统计学意义(P<0.05)。与对照组患者相比，研究组患者角膜水肿、后囊混浊以及眼压升高等并发症的发生率均有所降低，其中角膜水肿的发生率明显降低，差异具有统计学意义(P<0.05)。

结论：超声乳化摘除及人工晶状体植入术治疗高度近视白内障对于高度近视白内障患者术后视力的提高，以及术后并发症的降低均具有积极的促进意义。

METHODS:Selected from January 2012 to December 2013, 82 patients(96 eyes)with high myopia combined with cataract in our hospital as study group. The patients were divided into control group and study group randomly. There were 40 patients(46 eyes)in control group. There were 42 patients(50 eyes)in study group. The patients in control group were treated with small incision extracapsular cataract extraction and intraocular lens implantation. The patients in study group were treated with phacoemulsification and intraocular lens implantation. The visual acuity, best-corrected visual acuity and complications of corneal edema, posterior capsule opacification and increasing intraocular pressure of the patients in two groups were compared and analyzed. The patients' fundus stations were checked in study group after surgery.

RESULTS: Compared with control group, the patients in study group after treatment, the ratio of uncorrected visual acuity from 0.1 to 0.5, 0.5 to 1.0, 1.0 to 1.5 were increased significantly. There was no statistically significant(P<0.05). Compared with control group, the patients in study group after treatment, the ratio of best-corrected visual acuity from 0.1 to 0.5 was decreased significantly, only 28%, and the ratio of best-corrected visual acuity from 0.5 to 1.0 and 1.0 to 1.5 were increased significantly, up to 58% and 14%, there was statistically significant(P<0.05). Compared with control group, the patients in study group the incidence of complications of corneal edema, posterior capsule opacification and intraocular pressure were decreased, and the incidence of corneal edema was increased significantly, there was statistically significant(P<0.05).

CONCLUSION:Phacoemulsification and intraocular lens implantation has positively significant for improving best-corrected visual acuity effectively and reducing complications of the patients with high myopia combined with cataract.
