摘要
报告一组玻璃体切割气液交换并发白内障的病例。６２只眼中有８只眼为一过性白内障，２８只眼为不可逆白内障。一过性白内障表现为晶体后囊下混浊，形成为羽毛状或鳞状空泡样集簇混浊。发现晶体后残留玻璃体多，则并发白内障的机会就少。气体直接接触晶体影响代谢和营养是发生白内障的主要原因。建议为防止气体性白内障的发生，应在选择体位、静卧和气体种类的同时，尽可能少切除晶体后面的玻璃体。
AbstractCases with complicated cataract occurring aftervitrectomy and gas-liquid exchange were reported.Ina consecutive series of 62 eyes having undertaken theoperation,a transient cataract developed in 8 eyes andan irreversible cataract in 28 eves.The manifestationof the transient cataract is the posterior subcapsularopacity,feathery or placoid vacuolar in clusters in ap-pearance. It was found that if the amount of the resid-ual vitreous at the retrolental space is great enough,the chance of occurrence of complicated cataract isless.That the direct contact of the gas with the lensaffects the lens metabolism and nutrition is the chiefcause of the development of the cataract.It is suggest-ed that to prevent the development of cataract inducedby the gas, besides selection of body posture,quietstay in bed and proper selection of gas type,the vitre-ous at retrolental space be resected as little as possi-ble.
