方法：选择2011-01/2012-12在我院治疗的110例高度近视白内障患者作为研究对象，采用随机数字表法进行随机分组，观察组(乳化吸除人工晶状体植入组)56例，对照组(传统手术组)54例，术后观察两组矫正视力恢复情况、屈光度数及并发症情况，进行综合分析。

结果：观察组中矫正视力恢复至>0.5者30例，0.3～0.5者24例，<0.3者2例； 对照组中矫正视力恢复至>0.5者20例，0.3～0.5者22例，<0.3者12例； 两组间差异有统计学意义(P<0.05)。观察组中术后发生囊膜破裂者2例，玻璃体脱出者2例，并发症发生率为7.1%； 对照组中术后发生囊膜破裂者3例，玻璃体脱出者3例，悬韧带断裂者2例，并发症发生率为14.8%； 观察组与对照组相比，差异具有统计学意义(P<0.05)。观察组术后屈光度数偏差值<±0.50D者46例(82.1%)，屈光度数偏差值>±0.50D者10例(17.9%)； 对照组术后屈光度数偏差值<±0.50D者38例(70.4%)，屈光度数偏差值>±0.50D者16例(29.6%)，观察组与对照组相比，差异具有统计学意义(P<0.05)。

结论：超声乳化吸除人工晶状体植入治疗高度近视白内障的临床疗效好，具备切口小，眼内组织损伤小及术后视功能恢复时间短等优势，是治疗高度近视白内障有效安全的手术方式，值得临床推广应用。

METHODS: From January, 2011 to December, 2012, 110 patients with high myopia cataract were selected as the research objects in our hospital. They were randomly divided into observation group(emulsification aspiration and intraocular lens implantation group, n=56)and control group(conventional surgery group, n=54), the visual recovery and postoperative complications were observed in two groups and a comprehensive analysis were made.

RESULTS: This study showed: in observation group, 30 cases with the visual recovery back to above 0.5, 24 cases with the vision of 0.3-0.5, 2 cases with the vision of less than 0.3; In control group, 20 cases with the visual recovery back to above 0.5, 22 cases with the vision of 0.3-0.5, 12 cases with the vision of less than 0.3; The values were better than the control group, there was statistical significant differences(P<0.05). In observation group, 2 case was postoperative capsular membrane rupture, 2 cases were detached vitreous, the complication rate was 7.1%; In control group, 3 cases were postoperative capsular membrane rupture, 3 cases were detached vitreous, 2 cases were suspensory ligament rupture, the complication rate was 14.8%; there was statistical significance when compared observation group with the control group(P<0.05). The study showed: the observation group in postoperative refractive deviation <±0.50D in 46 cases(82.1%), refractive error value >±0.50D in 10 cases(17.9%), the control group with postoperative refractive deviation <±0.50D in 38 cases(70.4%), refractive error >±0.50D in 16 cases(29.6%), compared to the observation group and the control group, the difference was statistically significant(P<0.05).

CONCLUSION: The curative effects of phacoemulsification aspiration and intraocular lens implantation for the treatment of high myopia with cataract is effective, and it has the advantages of small incision, less intraocular tissue injury and short postoperative visual function recovery time. Therefore, it is an effective and safe treatment for high myopia with cataract, and it is recommended in clinical application.
