METHOD...AIM:To evaluate the long-term outcome of implantation of black diaphragm intraocular (BDI) lens combined with penetrating keratoplasty (PKP) for managing aphakic eyes with traumatic aniridia and corneal damage. METHODS: Six aphakic eyes of six patients with traumatic aniridia and corneal damage had BDI lens implantation at Qingdao Eye Hospital, Shandong Eye Institute from June 2008 to November 2011. Medical records of the patients were reviewed. Three patients received PKP and after 12-18months were implanted with BDI lens. The other three patients completed PKP and BDI lens implantation at the same time. The corrected visual acuity, intraocular pressure and number of corneal endothelial cells were monitored. RESULTS: The patients were followed up for an average of 24.3 ±12.1months (range 14-48 months). All BDI lenses were located well. The best corrected visual acuity got improved in 5 patients (0.1-1.0) and decreased in 1 patient from 0.4 to 0.2. Three patients had normal intraocular pressure (IOP) after implantation. Two patients required antiglaucoma medications to control IOP within the normal range and 1 patient implanted Ahmed glaucoma valve to control IOP. The corneal grafts kept transparent in all eyes and the corneal endothelial counting 】1 000/mm2 , although two patients experienced acute graft rejection and loss more than 30% corneal endothelial cells.CONCLUSION: Implantation of BDI lens combined with PKP is an effective option for managing aphakic eyes with traumatic aniridia and corneal damage. Although the results in our study are encouraging, additional studies of the long -term safety and efficacy are required. Alarger study population and longer follow-up may be beneficial.展开更多

文摘目的观察严重虹膜和晶状体损伤后Ⅰ期和Ⅱ期植入带虹膜隔人工晶状体的临床疗效。方法10例严重虹膜和晶状体损伤(脱位、缺如等)的患眼,手术治疗创伤后,Ⅰ期(3例)和Ⅱ期(7例)睫状沟位植入或缝线悬吊固定植入带虹膜隔人工晶状体,术后1 d,7 d,1个月,3个月观察术眼视力、切口、前房、人工晶状体位置、眼底、眼压。结果除1例Ⅰ期植入的患眼因术后前房出血和高眼压,于术后10 d 原切口取出人工晶状体外,其余9例患眼视力明显提高,术后3个月最佳裸眼视力0.5,最佳矫正视力0.6,患眼无畏光、眩光等视物不适症状。I期植入的患眼术后葡萄膜炎反应较Ⅱ期植入的患眼严重,且消退较慢。结论Ⅰ期植入带虹膜隔人工晶状体术后反应较重,应严格掌握适应证;Ⅱ期植入带虹膜隔人工晶状体适用于严重虹膜和晶状体损伤患眼的手术治疗。(中国眼耳鼻喉科杂志,2007,7:228-229)
