目的：通过对小切口非超声乳化白内障摘除术中黏弹剂娩核法与晶状体圈匙娩核法的疗效比较，探讨更适合在基层医院中推广应用的手术方法。
方法：抽取白内障患者146例166眼随机分为两组，对照组78例84眼，晶状体圈匙娩核； 试验组68例82眼，黏弹剂娩核。对比观察两种手术术后视力恢复情况及术中术后的并发症情况。
结果：小切口非超声乳化白内障摘除术黏弹剂娩核法与晶状体圈匙娩核法相比，两者术后后囊膜破裂的发生率相比差异有统计学意义(P<0.05)。术后视力，散光度及术后并发症比较差异无统计学意义(P>0.05)。
结论： 同晶状体圈匙娩核法治疗白内障相比较，黏弹剂娩核法能有效保护晶状体后囊膜，可在小切口白内障手术中进行推广。

[Abstract]
AIM: To compare the effect of treating cataract by sodium hyaluronate injection and lens-loop nucleus extraction of small incision cataract excision and explore more suitable method to promote the use of surgery in primary hospital.
METHODS: All 146 cataract patients(166 eyes)were allocated to two groups in random: the control group 78 patients(84 eyes)received conventional lens loop for extracapsular cataract extraction; the experiment group 68 patients(82 eyes)underwent nucleus extraction in small incision with sodium hyaluronate injection for extracapsular cataract extraction. Postoperative visual acuity and intraoperative and postoperative complications were compared between two groups.
RESULTS: Incidence of posterior capsule rupture difference was statistically significant(P<0.05)in small incision nucleus extraction with sodium hyaluronate injection compared with conventional lens loop for extracapsular cataract extraction. And there was no significant difference(P> 0.05)in postoperative visual acuity, astigmatism degree and postoperative complications compared with those of pre-operation.
CONCLUSION: Compared with the lens loop nucleus extraction, sodium hyaluronate injection for extracapsular cataract extraction can effectively protect the posterior lens capsule and can be promoted in small incision cataract surgery.
