摘要
目的总结分析儿童虹膜夹持型人工晶状体植入术后眼压、房角和角膜内皮的变化,探讨临床应用的有效性和安全性。方法 21例(30只眼)患者中,钝挫伤晶状体脱位2例,马-凡综合征晶状体脱位8例,外伤性白内障术后无晶状体眼4例,先天性白内障术后无晶状体眼7例。均无后囊支撑,无法行后房人工晶状体植入而应用虹膜夹持型人工晶状体植入术。术后观察视力、眼压、角膜内皮计数、房角改变等。结果随访3～12月(平均6个月),术后视力0.1～1.0,均较术前明显提高;眼压正常11～20 mm Hg,无继发性青光眼;角膜内皮细胞计数无明显变化;超声生物显微镜房角检查观察房角无明显改变。结论本手术时间短、操作简单,在不能常规植入后房型人工晶状体的特殊情况下选择虹膜夹持型人工晶状体植入术是安全有效的,无明显并发症发生,尤其是角膜内皮细胞计数无显著衰竭,对房角和玻璃体无干扰,是其最大优点。
Objective To discuss the efficacy and safety of clinical application of children＇s iris clip lens by analy- zing the changes of postoperative intraocular pressure, chamber angle and number of corneal endothelial cells. Methods 21 cases （ 30 eyes ） , whose posterior chamber were unable to be implanted with artificial lens because of absence of posterior capsule, were managed by implanting iris clip lens. The changes of postoperative visual acuity, ocular pressure, number of corneal endothelial cells, and chamber angle were studied. Results All patients were followed up, ranging from 3 ~ 12 moths { medium： 6months ）. Improvement of postoperative visual { 0.1 - 1.0 ） and normal ocular pressure （ 11 - 20 mm Hg）were achieved for all patients. Secondary glaucoma was not observed. The number of corneal endothelial cells and chamber angle by UBM were unchanged postoperatively. Conclusion Implantation of iris clip lens, which is easily manipulated, with short surgical duration and less complications , was proved to be efficient and safe , when difficulty is met with routine implantation of artificial lens in posterior chamber. The most advantage of this procedure is no decrease of corneal endothelial cells postoperatively and no influence on chamber angle and vitreous body intraoperatively.
