眼外伤晶体玻璃体切除术后Ⅱ期悬吊人工晶体植入术

目的:总结眼外伤行晶体玻璃体切除术后Ⅱ期悬吊人工晶体植入术的方法和疗效。方法:选择眼外伤后行晶体玻璃体切除术后的患者21例(21眼),均具有矫正视力>0.2、眼压稳定、眼底情况良好之条件,于3~6个月后行Ⅱ期悬吊人工晶体植入术。结果:随访1~6个月,平均4.5个月。矫正视力>0.5者6眼,0.3~0.5者10眼,0.1~0.2者4眼,<0.1者1眼。0.3及以上视力者16眼(80%)。术后裸眼视力比术前明显提高,矫正视力差异不大。结论:对于眼外伤行晶体玻璃体切除术后的患者,待眼部情况稳定3~6个月后行Ⅱ期悬吊人工晶体植入术是提高视力的理想方法,但要求术者需要具备一定的眼前后节手术经验,选择合适的病例。

Secondary suspended intraocular lens implantation after ocular trauma with lens-vitrectomy

Objective: To evaluate the effect of secondary suspended intraocular lens implantation after ocular trauma with lens-vitrectomy.Method: Twenty-one cases(21eyes) of ocular trauma were subjected to lens-vitrectomy,those whose corrected vision was 0.2 or more and intraocular pressure and eyeground were normal were subjected to the secondary suspended intraocular lens implantation 3 to 6 months later.Results: During a followed-up of 1 to 6 months(average 4.5 months),the corrected vision of 6 cases(6 eyes) was up to 0.6 or more,of 10 cases(10 eyes) was up to 0.3 to 0.5,of 4 cases(4 eyes) was between 0.1 to 0.2,and of 1 case was less than 0.1.The postoperative uncorrected vision was significantly higher than the preoperative,but the postoperative corrected vision was not significantly different from the preoperative.Conclusions: Secondary suspended intraocular lens implantation is a reasonable surgery for ocular trauma 3 to 6 months after lens-vitrectomy,but this needs experienced skill and proper cases.
