【摘要】 目的 :探讨肝素对人工晶体植入术后晶体表面色素沉着及后发障抑制效果。方法 :手术过程于灌注液中加入 5 0 u·ml- 1 (0 .4mg· ml- 1 )的肝素 ,共 76例 ,并随机选择普通人工晶体植入术 15 2例 ,手术后 1、 3、 7天观察晶体表面色素情况、测眼内压。并于半年至 2年后观察后囊混浊情况。结果 :应用肝素组术后人工晶体表面色素沉着较对照组明显减轻 (P<0 .0 5 ) ,后发障发生率低(P<0 .0 5 ) ,糖尿病性白内障、虹膜炎并发白内障 (外伤性白内障 )效果更显著。对角膜水肿程度及眼内压无影响。结论 :肝素能明显抑制人工晶体植入术后晶体色素沉着及后发障。可于手术中加入灌注液中应用更多还原

【Abstract】 To investigate the restraining effect of the heparin for pigment preciptation on surface of the intraocular lens and after catract.Methods:76patients who used 50 μ·ml -1 heparin in pouring fluid contrasted with 152 pationts without heparin.The pigment preciptation and intraocular pressure were observed on 1,3,7d and the rate of posterior capsular opacification on 6mo 24mo after operation.Results:The pigment preciptation and posterior capsular opacification were statistically significant between the patients with heparin and control group (P<0.05).It is effect apparently that the result at diabetic catract and catract complicated to iritis.Heparin hadnt an effect for degree of corneal edema.and intraoualar pressure.Conclusion:Heparin can restrain the pigment preciptation and after catract after intraocular lens implatation.It is available use in clinic.更多还原
