目的 :探讨角膜裂伤缝合术中使用粘弹性物质的效果。方法 :在 71例角膜裂伤缝合术中使用粘弹性物质形成前房 ,维持眼压 ,分离虹膜前粘连 ,保护眼内组织。结果 :术后 5 7例无虹膜前粘连 ,瞳孔圆 ;2例轻度虹膜前粘连 ,瞳孔欠圆 ;12例瞳孔严重变形 ,部分虹膜缺损。术后视力均有不同程度提高。结论 :粘弹性物质在角膜裂伤缝合术中有助于形成前房 保护眼内组织 ,分离虹膜嵌顿 ,利于缝合。
Objective: To investigate the effect of using viscoelastic material in corneal laceration. Methods: In 71 cases of corneal laceration and suture using viscoelastic material to form anterior chamber, maintaining intraocular pressure, separation of the anterior iris adhesions, the protection of intraocular tissue. Results: Fifty-seven cases had no pre-iris adhesions and pupil circles. Two cases had mild pre-iris adhesions and the pupils were not round. Twelve pupils were severely deformed with some iris defects. Postoperative visual acuity improved in varying degrees. CONCLUSION: Viscoelastic material helps to form anterior chamber for the protection of intraocular tissue in the process of corneal laceration and suture, and the iris incarceration is facilitated for suture.
