小切口非超声乳化技术在白内障手术中的应用效果及意义

Effect and significance of small incision non-phacoemulsification in cataract operation

目的探讨小切口非超声乳化技术治疗白内障与超声乳化治疗白内障效果。方法将100例白内障患者，120眼按入院先后顺序简单随机法分为对照组[50例60眼（超声乳化技术）]、观察组[50例60眼（小切口非超声乳化法）]，对照两组手术时间、手术后2周裸眼视力、角膜水肿及散光度的变化。结果两组患者手术时间、手术后2周裸眼视力、角膜水肿厚度及散光度比较差异有统计学意义（t=4．79、5．46、4．87、5．55，P〈0．05）。结论小切口非超声乳化技术较超声乳化治疗白内障具有操作时间短、前房波动小、手术并发症少的优势。

Objective To investigate the effect of small incision non-phacoemulsification technique and phacoemulsification in the treatment of cataract. Methods One hundred cataract patients with 120 eyes, according to the sequence of admission were divided into control group in 50 cases, 60 eyes （ small incision non phacoemulsification method） and the observation group in 50 cases, 60 eyes （ phacoemulsification technique）. To compare operation time, naked eye vision two weeks after surgery, corneal edema and changes of astigmatism between the two groups. Results There was significant differences on patients＇ operation time, naked eye vision two weeks after surgety, corneal edema thickness and astigmatism between the two groups （t = 4.79, 5.46, 4.87, 5.55, P 〈 0.05）. Conclusions Small incision non-phacoemulsification has advantage of shorter operation time, small fluctuations in anterior chamber, less complications compared to phacoemulsification in cataract operation.
