后房型人工晶状体两种缝线固定法的比较

The comparison between two kinds of suture fixation technique of posterior chamber intraocular lens

目的比较前房灌注下后房人工晶状体两种缝线固定方法的人工晶状体倾斜及偏中心等情况。方法对中山眼科中心自2007年5月至2010年8月24例（24眼）用内路法和外路法两种不同的缝线固定方法行二期人工晶状体固定术患者术前、术后的临床资料分析。结果（1）术前、术后矫正视力差异有统计学意义（P〈0．05）；术后矫正视力与裸眼视力差异有统计学意义（P〈0．05）。（2）术后各组的前房深度、晶体倾斜度和偏中心相比，差异无统计学意义（P〉0．05）。（3）术后并发症方面，两组之间并发症发生率差异有统计学意义（P〈0．05）。结论（1）两种缝线固定方法术后残余屈光不正对视力有明显的影响。（2）两种方法在术后人工晶状体倾斜度和偏中心的差异无统计学意义。（3）内路法组的并发症发生率高。

Objective To compare the introcular lens （IOL） tilt and decentration in the result of two kinds of suture fixation technique by anterior chamber perfusion. Methods To analyse the clinical data of 24 patients （24 eyes） in Zhongshan Ophthalmic Center from May 2007 to August 2010 by using two kinds of suture fixation technique of PC-IOL. Results 1. The correct visual acuity was significant change before and after surgery （P 〈 0.05 ）. There was significant change between uncorrected visual acuity and correct visual acuity after surgery（P 〈0.05）. 2. There was no significant change in the anterior chamber depth, IOL tilt and decentration between two groups （ P 〉 0.05 ）. 3. There was significant change in the total rate of surgical complications between two groups （P 〈 0.05）. Conclusion 1. There was significant effect in visual acuity by remnants of refractive errors between two groups. 2. The IOL tilt and decentration weren＇ t significant change between two groups. 3. The total rate of surgical complications of the internal group was higher than the external group.
