外伤性白内障手术116例临床分析

Clinical analysis of surgical treatment for 116 cases with traumatic cataract

目的分析外伤性白内障手术治疗的临床效果，探讨人工晶状体（IOL）植入时机。方法外伤性白内障116例（116眼）。I期行IOL植入79例，Ⅱ期IOL植入37例。结果I期和Ⅱ期IOL植入者手术后视力均明显提高，两者术后视力提高程度的差异无统计学意义（P〉0．05）；I期IOL植入者术后的葡萄膜炎、角膜水肿、IOL前膜及后囊浑浊并发症明显多于Ⅱ期IOL植入者，差异有统计学意义（P〈0．01）。结论IOL植入是治疗外伤性白内障、恢复视力唯一有效的方法，I期IOL植入虽然术后并发症多于Ⅱ期，经过治疗对术后的视力无影响，并且避免了二次手术。

Objective To analysis the clinical effect of surgical treatment for traumatic cataract, explore the appropriate time for intraocular lens （IOL） implantation. Methods The clinical data of 116 cases （116 eyes） of surgical treatment for traumatic cataract were retrospectively analyzed, 79 eyes had been implantated IOL, the other 37 eyes received secondary implantation. Results Both of the visual acuity of the patients by primary and secondary implantation were improved in evidence, but there were no change in ejec- tion fraction between primary and secondary implantation （P 〉 0.05 ）. In primary implantation , the postop- erative complications included uveitis, corneal bedewing , exudative membrane of IOL and opacity of post capsuta, which were apparently higher than secondary implantation ,with significant difference between each other （ P 〈 0.01 ）. Conclusion IOL implantation is the anly effective means of treatment for traumatic cataract and vision recovery. Though the postoperative complications of primary implantation is more than secondary implantation, it makes no difference to the vision after treatment, prevents the two-stage operation.
