目的探讨外伤致白内障人工晶状体植入术后眼部损害的临床表现、处理方法及其对视力的影响。方法对白内障人工晶状体植入术后因外伤致人工晶状体眼钝挫伤16例(16只眼)进行分析。结果 16例均有虹膜睫状体炎,经药物治疗后其中有2例虹膜与人工晶状体粘连;人工晶状体夹持2例,经手术后复位;5例有不同程度的前房出血,经双眼包扎及药物治疗后,前房出血消失;13例因伤口裂开进行手术修复,瞳孔有不同程度的上移,其中1例人工晶状体半脱位,予行缝线固定术。16例治疗后期有10例发生后发性白内障;视力保持不变3例, 视力下降13例。结论人工晶状体眼钝挫伤具有以下几个特点:(1)术后护理不当早期揉眼或轻度挫伤即会造成较明显的眼部损害;(2)伤后均会发生不同程度的虹膜睫状体炎,伴有瞳孔区纤维膜形成的较多;(3)伤后造成伤口裂开伴有玻璃体脱出时应尽早手术,先行玻璃体切除后再行伤口缝合;(4)伤后后期发生后发障的比例明显增高,大部份视力有不同程度下降;(5)人工晶状体植入术后要特别注意术眼的保护,如术眼受到钝挫伤应早期发现、及时治疗。
Objective To investigate the clinical manifestations and treatment of ocular damage after cataract surgery with traumatic cataract and its effect on visual acuity. Methods 16 eyes (16 eyes) with traumatic intraocular lens (IOL) contusion after cataract extraction were treated with IOL implantation. Results 16 patients had iridocyclitis. After drug treatment, there were 2 cases of iris and intraocular lens adhesions. Intraocular lens (IOL) was held in 2 cases and was reset after operation. In 5 cases, there were different degrees of anterior chamber hemorrhage. And drug treatment, the anterior chamber hemorrhage disappeared; 13 cases of wound rupture for surgical repair, the pupil with varying degrees of up, including 1 case of intraocular lens dislocation, suture fixation. There were 10 cases of posterior cataract in 16 cases in the later stage of treatment; 3 cases remained unchanged and 13 cases showed decreased vision. Conclusion IOL has the following characteristics: (1) improper postoperative care of Rouyan or mild contusion will cause more obvious eye damage; (2) after injury will occur to varying degrees of iris and ciliary Body inflammation, accompanied by the formation of the pupil zone fiber membrane more; (3) caused by injury wound rupture with vitreous prolapse should be as soon as possible surgery, the first line after vitrectomy and wound suture; (4) (5) IOL implantation should pay special attention to the protection of the eye, such as eye surgery should be early detection of blunt contusion, timely treatment.
