小切口非超声乳化人工晶状体植入术临床观察

The clinical observation of small incision nonphacoemulsification andintraocular lens implantation

目的探讨小切口非超声乳化人工晶状体植入手术疗效。方法对１９７例２３６眼行常规囊外摘出术、小切口非超声乳化术和超声乳化术，并对手术后视力和角膜曲率结果做比较分析。结果小切口非超声乳化术术后视力恢复快、散光小，与超声乳化组结果相似，与常规大切口手术组相比散光较小，视力较好（Ｐ＜０．０１）。结论小切口非超声乳化术是较有效控制白内障手术后角膜散光的一种方式。

ObjectiveTo investigate the therapeutic effects of small incision nonphacoemulsification and intraocular lens implantation.MethodsThe visual acuity and corneal refractivity of 236 eyes (197 patients) undergone conventional extracapsular extraction or small incision nonphacoemulsification and phacoemulsification were examined and compared in postoperative period.ResultsSmall incision nonphacoemulsification and intraocular lens implantation provided patient with rapid visual rehabilitiation,less surgically induced astigmatism,and almost the same results as that in phacoemulsification group.Corneal refractivity in small incision nonphacoemulsification group was significantly less ( P <0.01)and visual acuity was much better ( P >0.01)than that in large incision group.ConclusionSmall incision nonphacoemulsification is a more effective method to control postoperative corneal astigmatism in cataract surgery.
