研究通过改良的虹膜缝合技术来扩大玻璃体切除手术中遇到的小瞳孔这一新技术。用尖刀在角膜缘1∶30,10∶30,4∶30和7∶30分别做四个小切口,带有10-0聚丙烯缝线的直针和Sinskey人工晶状体钩把瞳孔的边缘固定于角膜缘。3例患者,缝合四针形成了6mm和9mm大小的方形瞳孔,在手术结束后,又可恢复至较小瞳孔。这一方法简单,并且可减少术后并发症。

To describe a modified simple iris suture for pupillary dilation technique during vitrectomy in cases with a miotic pupil.Four translimbal incisions were created with a sharp straight blade at 1∶30,10∶30,4∶30,and 7∶30 o’clock,respectively.The straight needle of 10-0 polypropylene suture and a Sinskey IOL hook was used to displace the pupillary margin toward the limbus.In 3 cases,four sutures caused a 6-mm to 9-mm square-shaped pupil,and the pupil was allowed to return to a smaller size at the end of the operation.It is simple and may reduce postoperative complications.
