Bigbag和Rayner620H人工晶状体在高度近视患者白内障术中的应用对比

目的：：探讨Bigbag和Rayner620 H人工晶状体在高度近视患者白内障手术植入术中的应用效果比较。方法：选取2014-01/2015-03在我院就诊拟行白内障超声乳化吸除联合人工晶状体植入术高度近视患者77例128眼,采用 Bigbag 人工晶状体39例65眼,采用Rayner620 H人工晶状体38例63眼。测量和记录两组患者术后1 mo后BCVA分布情况、实际屈光度和术前预留屈光度差值、并发症等情况。结果：采用 Wilcoxon 秩和检验比较 Bigbag 组和Rayner620H组BCVA,差异具有统计学意义(P<0.05)；两组屈光度预测值差异具有统计学意义( P<0.05)。 Bigbag组患者自觉眼前黑影飘动、后囊膜混浊及皱褶发生的例数少于Rayner620 H组,两组比较差异具有统计学意义( P<0.05)。结论：Bigbag人工晶状体对白内障超声乳化吸除联合人工晶状体植入术高度近视患者的效果好,能减少术后不良因素的发生。

Comparison of Bigbag and Rayner620H intraocular lens in cataract surgeries in high myopia patients

AIM:To investigate the effects of Bigbag and Rayner620H intraocular lens in cataract surgeries in high myopia patients.

METHODS:Seventy-seven patients(128 eyes)were treated by phacoemulsification combined with intraocular lens implantation from January 2014 to March 2015 in our hospital. Thirty-nine patients(65 eyes)were treated with Bigbag intraocular lens, 38 cases(63 eyes)were treated with Rayner620H. The best corrected visual acuity(BCVA)distribution, the actual refractive value, the difference between predictive refractive value and actual refractive value and complications were measured and recorded in the two groups at 1mo after surgeries.

RESULTS:The difference between the two groups on BCVA are statistically significant(P<0.05), compared by Wilcoxon rank sum test. The differences between predictive refractive value and actual refractive value of the two groups were statistically significant(P<0.05). The numbers of patients with shadow fluttering, posterior capsule opacification and wrinkling in Bigbag group were less than those in the Rayner620H group(P<0.05).

CONCLUSION:The effect of Bigbag intraocular lens for patients with phacoemulsification and intraocular lens implantation is good, and it can reduce the risk of complications.
