前房维持器在合并外伤性白内障的眼内异物伤玻璃体手术中的应用

目的评价前房维持器灌注在对选择的病例行外伤性白内障摘出联合眼内异物摘出的玻璃体手术中的应用效果。方法36例（36眼）眼球穿孔伤合并白内障及眼内异物，排除术前已诊断合并视网膜脱离、外伤性眼内炎者。白内障摘出术中在前房维持器液体灌注下行白内障皮质清除，然后继续应用前房维持器行眼内液体灌注，联合20G玻璃体手术摘出眼后段异物，人工晶状体植入。术中始终应用前房维持器行眼内液体灌注。结果36例眼内异物均成功摘出。术后视力提高者36例，其中视力达0．1以上者34例（94％）。无大泡性角膜病变发生。1例视网膜脱离，经巩膜扣带术视网膜复位。结论经前房维持器灌注可代替经巩膜切口灌注应用于外伤性白内障摘出联合眼内异物摘出的玻璃体手术中，提供了另一种眼内液体灌注方式，可减少并发症。

Application of anterior chamber maintainer in vitrectomy for trauma with intraocular foreign body and cataract

Objective To evaluate the clinical effects of anterior chamber maintainer to infuse fluid in vitrectomy combined with traumatic cataract extraction and intraocular foreign body extraction.Methods Without retinal detachment and endophthalmitis,36 cases (36 eyes) ocular perforation injury with cataract and foreign body were treated by vitrectomy in combination of catract extraction,intraocular foreign body extraction and IOL implantation.In this process,the anterior chamber maintainer was used for irrigation.Results The foreign bodies of 36 eyes were extracted successfully.The postoperative visual acuity improved in 36 cases,and visual acuity was 0.1 or better in 34 eyes (94％).No bullous keratopathy occurred,retinal detachment in one case and recovered after scleral buckling.Conclusion In vitrectomy,infusing by anterior chamber maintainer could take the place of via scleral incision with fewer complications.
