目的探讨白内障术中后囊破裂行Ⅰ期前房型人工晶状体植入的效果和安全性。方法27例(27眼)白内障术中发现后囊破裂、玻璃体脱入前房,经前段玻璃体切除后,植入PMMA弹性开放襻一体式前房型人工晶状体(AC-IOL)。结果术后1周及1个月视力≥0.3者分别为85.2%和88.9%,≥0.5者分别为70.4%和81.5%。术后并发症角膜水肿、葡萄膜炎和眼压升高均在1周内恢复正常,在襻的周围有局限性房角粘连。结论弹性开放襻一体式前房型人工晶状体植入术操作简单,视力恢复好,并发症较少,可作为后房型人工晶状体植入失败补救措施的首选方法。
Objective To investigate the effect and safety of primary posterior chamber intraocular lens implantation in posterior capsule rupture in cataract surgery. Methods 27 cases (27 eyes) of posterior capsular rupture were found during cataract surgery. The vitreous body was removed into the anterior chamber. After anterior vitrectomy, PMMA elastic open 襻 anterior chamber intraocular lens (AC-IOL) was implanted. Results One week and one month after operation, the visual acuity ≥0.3 was 85.2% and 88.9% respectively, and those with ≥0.5 were 70.4% and 81.5% respectively. Postoperative complications of corneal edema, uveitis and elevated intraocular pressure were normal within 1 week, there are limitations around the corner of the angle of adhesion. Conclusions The elastic open 襻 one-piece anterior chamber intraocular lens implantation is simple, the visual acuity recovery is good, and the complication is less. It can be used as the first choice for the remedial measures of failed posterior chamber intraocular lens implantation.
