晶状体或人工晶体脱入玻璃体腔的手术处理

目的探讨晶体或人工晶体脱位入玻璃体腔的处理方法。方法钝挫伤后晶体脱位3眼,白内障手术中或术后晶体或人工晶体脱位11眼。均采用标准睫状体扁平部三切口闭合式玻璃体切除方式。术中注入全氟化碳液体0.4～4ml。经角膜缘取出人工晶体或晶体,或是直接玻璃体腔内粉碎晶体。再植入前房型人工晶体,或行后房型人工晶体睫状沟缝线固定。结果14眼均顺利取出或粉碎玻璃体腔内晶体或人工晶体。13眼(92.86%)术中植入人工晶体。术后视力明显提高12眼(85.71%)。结论对晶体或人工晶体全脱位进入玻璃体腔者,需争取早期采用玻璃体切除联合脱位晶体或人工晶体取出或粉碎手术,争取再植入人工晶体。

Management of posteriorly dislocated lens or intraocular lens

Objective To evaluate the surgical skills of managing the lens or intraocular lens dislo- cated into the vitreous cavity. Methods Lens dislocated after blunt trauma in 3 eyes, and in 11 eyes, lens or intraocular lens dislocated in or after cataract surgery. Standard pars plana vitrectomy and 0.4-4.0ml perfluorocarbon fluid were used in these 14 eyes. Lens or intraocular lens were removed through the limbal region, or some lens were fragmented in the vitreous cavity. Anterior intraocular lens or ciliary sulcus fixation lens were implanted at the same time. Results The dislocated lens or intraocular lens were all removed or fragmented successfully in these 14 eyes. Introuclar lens were implanted in 13 eyes(92.86%),and the visual acuity increased significantly in 12 eyes(85.71%). Conclusions Vitrectomy, removal or fragmentation of dislocated lens or intraocular lens should be given to these eyes as early as possible. Intraocular lens implanta- tion at the same time was recommended.
