角膜穿孔伤的屈光性缝合手术

目的　探讨角膜穿孔伤手术缝合中运用辅助手段减轻术后角膜散光 (屈光性缝合 )的方法。方法　术中采用黏弹剂、缩瞳剂、辅助切口及相应的缝合技巧 ;术后合理应用治疗性角膜软性接触镜。结果　 10 8例 10 9眼术后角膜创口愈合良好 ,瘢痕小 ,不规则散光减轻 ,其中 49眼术后健眼与患眼角膜地形图参数值显示差异无显著性意义 (P >0 .0 5 )。结论　角膜穿孔伤创口修复时采用相应的辅助手段能有效减轻术后角膜散光状态 ,重建原有的角膜外形

Refractive sutures for corneal perforating injury

Objective To investigate the method of lightening astigmatism and regaining cornea refraction state in the operation of corneal perforating injury.Methods In the operation,we used the viscoelastic,miotic,side port and suture skills.After the operation,we used the curative corneal contact lens reasonably.Results After surgery,cornea wounds healed well in most cases,and the irregular astigmatism was lightened.There was little difference in the parameter of corneal topography with healthy and wounded eyes in 49 cases( P >0.05).Conclusion In the repair of corneal perforating injury,the cornea astigmatism can be lightened with some methods.And the cornea shape of wounded eyes can be rebuilded.
