目的:探讨瞳孔缘虹膜环形剪除法在粘连性小瞳孔白内障超声乳化术的安全性和手术技巧。方法:对23例34眼粘连性小瞳孔的白内障患者采用钝性分离及瞳孔缘虹膜环形剪除法,进行原位超声乳化联合人工晶状体植入术。结果:术后随访6mo,所有病例术后矫正视力较术前有不同程度的提高。术后视力<0.1者3眼,0.1～0.3者3眼,～0.6者12眼,>0.6者16眼。结论:对粘连性小瞳孔的白内障患者采用瞳孔缘虹膜环形剪除法,可以保证原位超声乳化术安全进行,术后视力恢复理想,手术并发症少。

AIM:To explore the surgical techniques and the clinical effects of continuous pupillary collar cutting of phacoemulsification in microcoria cataract.METHODS:Twenty-three cases(34 eyes) of microcoria cataract were operated using manual pupilloplasty first,then were performed by continuous pupillary collar cutting,phacoemulsification and foldable intraocular lens implantation.RESULTS:During the follow-up of 6 months,all the cases got better visual acuity,the corrected visual acuity was less than 0.1 in 3 eyes,being 0.1-0.3 in 3 eyes,0.3-0.6 in 12 eyes and above 0.6 in 16 eyes.CONCLUSION:By using continuous pupillary collar cutting of phacoemulsification in microcoria cataract,this technique ensures the safety during surgery as well as improves the visual acuity with few complications.
