瞳孔整复术在人工晶体植入中的应用

目的：对临床上遇到的合并有虹膜缺损、瞳孔散大、瞳孔移位的无晶体眼或白内障病例，植入人工晶体的内时行瞳孔整复术，以恢复瞳孔的圆形及居中，提高术后视力并预防单眼复视、眩光等。方法：9点至3点方位的虹膜缺损及瞳孔上移者用10－0聚丙烯缝线直接在上方切口处行虹膜缝合（开放式）；3点至9点方位的虹膜缺损则采用前房外缝合虹膜（闭合式）。结果：22例中术后视力0．5以上者占65％，瞳孔接近圆型占67％，瞳孔直径小于等于3mm占73％，瞳孔基本居中占67％。结论：人工晶体植入的同时进行瞳孔整复术，可以使各种原因引起的瞳孔变形恢复接近正常的形态、大小有位置；聚丙烯缝线应用于虹膜缝合，反应轻，效果好。

Application of Corepraxia in the Implantation of Intraocular Lens

Purpose: In the cases of aphakia or cataract which complicated with iridosteresis, corecta-sis and pupil displacement, corepraxia was performed when implanting intraocular lens (IOL) in order to recover the normal shape and position of pupil, improve postoperative visual acuity and prevent monodiplopia and glare.Methods: In the cases which have iridosteresis at the direction of 9 ~ 3 oclock or up-drawn pupil, iris suture was performed at the incision directly(open method); while those at the direction of 3 ~ 9 o'clock, operation was performed outside the anterior chamber (close method).Results: In 22 cases, the percentage which having visual acuity better than 0. 5 is 65% , having nearly round shape pupil 67% , having pupil diameter less than 3 mm 73% , having normal pupil position 67% .Conclusion: All kinds of deformed pupil can be recovered to their normal shape, size and position by performing corepraxia while IOL was implanted. The prolene has light reaction and better effect in iris suture. Eye Science 2001; 17: 96 - 98.
