不同术式治疗老年性自内障临床研究

目的探讨两种不同手术方式治疗老年性白内障术后的临床疗效。方法选择2011年1～12月科室收治的老年性白内障患者60例，按随机数字表法将患者分为小切口白内障囊外摘除联合人工晶体植入术组（观察组）和白内障超声乳化术组（对照组），每组30例，比较两组患者的视力变化、术后泪膜破裂时间（BUT）和基础泪液分泌（SIT）。结果观察组与对照组的总有效率分别为76．67％、63.33％。观察组视力≥0．3的患者26例（86．67％），对照组视力≥0．3的患者23例（76．67％），术后1d、3d两组的SIT、BUT平均值明显增加，差异有统计学意义（P〈0．05）。结论小切口白内障囊外摘除联合人工晶体植入术治疗老年性白内障，安全性较高，改善了老年白内障患者的视力、BUT、SIT等，减少干眼症状的发生率．减轻了老年白内障患者的痛苦．提高患者的生活质量。

Clinical research of different surgical methods for treatment of senile cataract

Objective To explore the clinical effects of two different surgical methods for the treatment of senile cataract.Methods Sixty patients with senile cataract treated in the departments from January 2011 to December 2011 were randomly divided into the small incision extracapsular cataract extraction combined with intraocular lens implantation group(observation group) and the cataract phacoemulsification group(control group) according to the random number table,with 30 patients in each group respectively.The vision change,postoperative tear film breakup time(BUT) and SchirmerⅠtest(SIT) of both groups there was compared.Results The total effective rate was 76.67% and 63.33% for the observation group and the control group respectively.In the observation group,26 patients(86.67%) had visual acuity ≥ 0.3;In the control group,23 patients(76.67%) had visual acuity ≥ 0.3.The mean SIT and BUT of both groups 1 hour and 3 hours after surgery increased obviously with a statistically significant differences(P < 0.05).Conclusion Small incision extracapsular cataract extraction with intraocular lens implantation for the treatment of senile cataract has high safety,improves the visual acuity,BUT and SIT of patients with senile cataract,reduces the incidence of dry eye symptoms,thereby reducing the pain of patients with senile cataract and improving patients’ quality of life.
