后房型人工晶状体取出70例临床分析

Clinical. analysis of posterior chamber intraocular lens extraction in 70 Cases

目的探讨后房型人工晶状体取出原因与治疗措施。方法回顾在眼科住院的70例（70只眼）行后房型人工晶状体取出术病例的临床资料，分析人工晶状体取出原因与方法，记录手术前后人工晶状体位置、最佳矫正视力及并发症的发生情况。结果在70例人工晶状体取出病例中，人工晶状体全脱位与不全脱位53只眼；眼内炎8只眼；视网膜脱离9只眼；继发性青光眼4只眼；大泡性角膜病变1只眼；人工晶状体度数错误1只眼；瞳孔夹持1只眼；人工晶状体混浊1只眼。单纯人工晶状体取出26只眼，人工晶状体置换44只眼。术后患者视力均有所提高。手术前后最佳矫正视力比较，差异具有统计学意义（P〈0．05）。术后无严重并发症发生。结论人工晶状体取出是人工晶状体植入术后出现并发症严重影响患者视功能的有效处理措施。

Objective To investigate the causes and methods of posterior chamber intraocular lens extraction surgery. Methods The clinical data of 70 cases with posterior chamber intraocular lens extraction were retrospectively analyzed. The reasons and methods of the surgery were summarized. Main outcome included the position of IOL, best-corrected visual acuity, slit-lamp biomicroscopy and complications. Results Among the 70 cases： intraoeular lens dislocation or semi-dislocation in 53 eyes, endophthalmitis in 8 eyes, retina detachment in 9 eyes, secondary glaucoma in 4 eyes, bullous keratopathy in 1 eye, intraocular lens degree error in 1 eye, pupil campling in 1 eye, opacification of the IOL in 1 eye. Forty-four eyes were implanted with new intraocular lens in the same operation, the rest were not implanted intraocular lens. Postoperative best-corrected visual acuity was better than preoperative best-corrected visual acuity （P 〈0.05）. No serious postoperative complication was observed during follow-up. Conclusions IOL extraction is an effective way to deal with severe postoperative complication.
