目的 :探讨治疗虹膜缺损无晶状体眼和伴虹膜缺损外伤性白内障的有效方法。方法 :对因手术或外伤致虹膜缺损的 18例 ( 18只眼 )无晶状体眼和 9例 ( 9只眼 )虹膜缺损外伤性白内障患者 ,施行缝线固定带虹膜隔后房型人工晶状体手术。结果 :术后随访 4～ 15个月 ,平均 8 5个月。与术前相比 ,术后视力提高 ,具有显著性差异 (P <0 0 1) ;2 6只眼畏光症状消失 ,1只眼仍轻度畏光。术后眼压增高 ( >2 1mmHg)者 3只眼 ,其中 2只眼为玻璃体切割术后眼 ,经局部用药眼压降至正常范围。所有病例人工晶状体均无偏位 ,均未发生睫状体出血和视网膜脱离。结论 :缝线固定带虹膜隔后房型人工晶状体手术是治疗虹膜缺损无晶状体眼和伴虹膜缺损外伤性白内障的有效方法 ,但其价格昂贵 ,且术后葡萄膜反应重 ,应严格掌握适应证。
Objective: To explore effective methods for the treatment of aphakic eyes with iris defect and traumatic cataract with iris defects. Methods: 18 cases (18 eyes) of aphakic eyes and 9 eyes (9 eyes) of iris-deficient traumatic cataract who had iris defect caused by operation or trauma were performed suture fixation with IOL and posterior chamber intraocular lens implantation. Results: The patients were followed up for 4 to 15 months with an average of 85 months. Compared with the preoperative, postoperative visual acuity increased significantly (P <0.01); 24 eyes photophobia symptoms disappear, one eye still mild photophobia. Postoperative intraocular pressure (> 2 1mmHg) were 3 eyes, of which 2 eyes after vitrectomy eye, local medication by intraocular pressure dropped to the normal range. All cases of intraocular lens were no deviation, no ciliary body bleeding and retinal detachment. CONCLUSIONS: Suture fixation with iris diaphragm posterior chamber intraocular lens (IOL) surgery is an effective method for the treatment of aphakic iris and traumatic cataract with iris defect. However, it is expensive and the response to uveal reaction is heavy. Indications should be strictly controlled.
