目的观察指环状或部分指环状板层角膜移植对Terrien角膜边缘变性的治疗效果。方法2000年1月~2003年3月角膜组病房收治Terrien角膜边缘变性患者15例共17只眼。其中男性10例,12只眼,女性5例,5只眼。年龄29~65岁。病史3~20年。患眼视力为指数~0.2不等。手术方法:根据病变的范围,作指环状或部分指环状板层角膜移植。结果术后一周内,植片可轻度水肿,以后渐变清亮,厚度为正常角膜厚度,术后观察6月~3年,未见病变复发者。术后视力均有明显提高,术后6月,视力1.0以上5只眼,>0.5~1.0者6只眼,0.1~0.5者6只眼。结论指环状或部分指环状板层角膜移植术可以控制Terrien角膜边缘变性的病情发展,恢复病变区角膜正常厚度,减少散光,改善角膜曲率,提高患眼视力,预防角膜穿孔,远期疗效稳定,是治疗Terrien角膜边缘变性安全有效的疗法。
Objective To observe the effect of ring-shaped or partial ring-like corneal transplantation on the treatment of Terrien corneal edge degeneration. Methods From January 2000 to March 2003, 15 patients with corneal limbal degeneration in corneal ward were treated with 17 eyes. Including 10 males, 12 eyes, 5 females, 5 eyes. Age 29 to 65 years old. History of 3 to 20 years. Eye vision for the index ~ 0.2 range. Surgical methods: According to the extent of the lesion, ring finger or part of the ring means that the corneal graft. Results Within one week after operation, the implants could be slightly edematous. After that, the grafts were clear and bright, the thickness was normal corneal thickness. The patients were observed from June to 3 years after operation, and no recurrence was found. Postoperative visual acuity was significantly improved in 6 months after surgery, visual acuity of 1.0 above 5 eyes,> 0.5 to 1.0 in 6 eyes, 0.1 to 0.5 in 6 eyes. Conclusion The ring-shaped or partial ring-shaped lamellar keratoplasty can control the progression of Terrien’s corneal degeneration, restore the normal corneal thickness, reduce astigmatism, improve corneal curvature, improve visual acuity, prevent corneal perforation, and long-term curative effect. Is a safe and effective therapy for the treatment of Terrien’s corneal edge degeneration.
