板层角膜移植镶嵌术治疗角膜穿孔

目的：通过对角膜深层异物剔除术后发生角膜穿孔的患者实施板层角膜移植镶嵌术的临床观察总结，探讨角膜穿孔的临床治疗方法。方法：对1999年～2002年间5例因角膜深层异物剔除术后发生角膜穿孔、经保守治疗一周无效的患者进行板层角膜移植镶嵌术，对术后一年的临床随访观察资料进行总结讨论。结果：5例患者角膜穿孔均获得良好愈合，术后前房形成良好，眼前节炎症迅速控制，视力恢复快，经一年后视力达0．15～1．0，平均视力0．51。裂隙灯下检查角膜穿孔区轻度瘢痕性浑浊呈半透明状，余处角膜透明，均无新生血管。5例患者虹膜均无前后粘连。角膜曲率及角膜地形图显示轻度陡峭或扁平，无显著改变。结论：板层角膜移植镶嵌术是治疗角膜深层异物剔除术后角膜穿孔的有效方法。

Lamellar Corneal Graft Certosina for Corneal Perforation

Purpose: To explore the treatment of corneal perforation, lamellar corneal graft cetosina was performed in patients with corneal perforation by operation of eliminating foreign body in deep cornea.Methods ? Five patients with operation of eliminating foreign body in deep cornea were treated with lamellar corneal graft certosina from 1999 to 2002.These five cases were all offered 1-week conservative therapy but without curative effect. The period of postoperative follow-up was 1 year.Results:All five cases were healed,and attained satisfying anterior chamber.The inflammation of each anterior pole of eye was controlled quickly .The visual acuity was all improved quickly. The visual acuity was 0.15-1.0 (mean;0.51) after one year follow-up. Slit-lamp examination showed translucence slight cloudy in the areas of corneal operation.The rest areas of cornea were transparent.No corneal neovascular and fore-and-aft iris conglutination appeared.There was no obvious change by the keratometer and corneal topography.Conclusion: Lamellar corneal graft certosina is an effective method for patients with corneal perforation due to operation of eliminating foreign body in deep cornea.
