摘要
目的 探讨外伤性白内障人工晶状体不同的植入方式。方法 对 3 6例 ( 3 6眼 )外伤性白内晶状体囊损伤情况 ,选择不同的手术。其中 2眼植入前房人工晶状体 ,2 0眼常规植入后房 ,13眼行缝线固定术。结果 术后 3月矫正视力。 <0 5者 16眼 ,( 44 44 % ) ,0 5～ 0 8者 14眼 ( 3 8 89% ) ,达 1 0者 6眼 ( 16 67% )。缝线固定术较常规后房植入术更易发生眼内出血和人工晶状体移位 ,术后反应较重。结论 截囊时尽可能保留前囊 ,以备后囊破损较大时代替后囊做支托植入后房人工晶状体 ,后囊中央破口 <4mm或周边破裂 <12 0°者可常规植入后房 ,如后囊破损超过上述范围 。
Objective To observe the operative methods and complication of intraocular lens implantation in cases of traumatic cataract.Methods 36 patients of traumatic cataract with rupture of lens capsule,AC-IOL was performed in 2 eyes,PC-IOL performed as usual in 20 eyes,PC-IOL performed with suture fixation in 13 eyes.Results 3 months after operation,the corrected visual acuity<0.5 in 16 eyes(44.4%),0.5-0.8 in 14 eyes(38.9%),≥1.0 in 6 eyes(16.7%).PC-IOL performed with suture fixation would cause hemalopia compared with PC-IOL performed as usual and the reactions after operation was strong.Conclusion Anterior lens capsule should try to keep,which can be prepared to be the bracket for performing PC-IOL instead of posterior lens capsule when serious repture of posterior lens capsule appeared.And central repture of posterior lens capsule<4mm,periapheral repture<120°,should perform PC-IOL.If repture scale is beyond the above mentioned,PC-IOL should be performed with suture fixation.
