玻璃体腔内超声乳化治疗晶状体后脱位的疗效观察

目的 评价玻璃体腔内超声乳化治疗晶状体后脱位的疗效.方法 选取2007年11月至2009年11月,18例(18只眼)因眼伤或白内障摘除术中后囊破裂晶状体核脱位于玻璃体腔的患者,应用标准睫状体扁平部闭合式三切口,先行全玻璃体切除术,再采用去硅胶袖套的超声乳化头乳化摘除脱位的晶状体,并根据病情行眼内异物取出术、视网膜激光光凝术等.术后观察视力、眼压、视网膜、巩膜伤口等恢复情况.结果 在没有使用全氟化碳(重水)的情况下,所有晶状体均成功摘除,没有发生严重的并发症.13只眼术后视力不同程度提高,其余5例保持不变;术前合并继发性青光眼的6例患者,术后眼压控制良好;术前合并球内异物的3例均成功取出异物;视网膜、巩膜无明显医源性损伤.结论 玻璃体腔内超声乳化联合玻璃体切割治疗晶状体后脱位疗效好,具有方便、快捷、不需应用重水的特点.超声乳化头可以代替超声粉碎头用于晶状体脱位于玻璃体腔的治疗.

Removal dislocated lenses in vitreous cavity by intravitreal phacoemulsification

Objective To evaluate the effect of phacoemulsification to remove the dislocated lens in vitreous cavity. Methods Between November 2007 and November 2009, the authors studied retrospectively 18 cases (18 eyes) with posterior dislocation lens because of ocular trauma or cataract surgery, and underwent phaco devoid the silicone sleeve combined the total pars plana vitrectomy. According to different cases, extraction of foreign body and coagulation of retina laser were chosen after lens was removed. The main outcome measures were visual acuity, intraocular pressure, retina and sclera healing post-operation. Results All dislocated lenses were successfully removed without perfluorocarbon. No complications occurred during phacoemulsification. Visual acuity (with glasses correction) improved in 13 eyes (72.2%) and was unchanged in remain 5 eyes. Secondary glaucoma in 6 eyes was corrected and the foreign body in 3 eyes was extracted postoperation. There was no retinal detachment, retinal hemorrhage and sclera burning. Conclusions We can use the phaco probe devoid of the silicone sleeve to remove the dislocation lens in vitreous cavity without phacofragmentation. This way is effective, easy and dose not need the perfluorocarbon injection.
