报告老年性白内障72只眼行囊升摘除及后房型人工晶体植入术，其中35只眼术中于林格氏液中加入肝素（25u／ml）;37只眼作为对照．肝素组有1只眼于术后1天出现前房出血，量较少，于第三天吸收；对照组术中有1只眼出现前房出血，量不多，待其出血自行停止后，用针将血块吸出．其后未再发生出血．出血情况二级差异无显著性（P＞0．05），人工晶体前膜形成及后囊混浊情况肝素组少于对照组．术后半年时肝素组视力为0．68±0.28，明显高于对照组的0.51±0.22（P＜0．05）．
Thirty-two eyes of senile cataract were enrolled in this study. Excision of capsulotomy and posterior chamber intraocular lens implantation were performed in 72 eyes. Thirty-five eyes were treated with heparin (25u / ml) in Ringer’s solution and 37 eyes were used as control. In the heparin group, 1 patient had anterior chamber hemorrhage at 1 day after operation, which was less and was absorbed on the third day. In the control group, 1 patient had bleeding in the anterior chamber in a small amount. After he stopped bleeding, Needle will clot suck out. No further bleeding occurred thereafter. There was no significant difference in secondary bleeding (P> 0.05). The incidence of posterior capsular opacification and posterior capsular opacification was lower in heparin group than in control group. Six months after operation, the visual acuity of the heparin group was 0.68 ± 0.28, significantly higher than that of the control group (0.51 ± 0.22, P <0.05).
