摘    要:目的:探讨用表面角膜镜片术治疗严重的Terrien's边缘角膜变性的效果。方法:全部病例为严重的周边角膜环形或部份变薄,厚度小于正常1/3,用带2mm环形巩膜的全角膜板层移植片移植到去除上皮的角膜植床。手术前及手术后定期行角膜曲率,散瞳验光检查。结果:本组病例随访时间3 ̄13个月,平均10个月。随访期间,镜片全部透明。术前角膜散光平均11.5D,术后散光平均3.9D。术后矫正视力除一例稍降外,3例

Abstract:PURPOSE: To evaluate the efficacy of epikeratophakia for the treatment of severe Terrien's degeneration. METHODS: Four eyes with severe Terrien's corneal degeneration are studied. The lesions were located at the peripheral cornea and the corneal thickness was less then 1/3 of normal. Plano keratoplasty was performed. A lamellar lenticule with a 2 mm scleral rim was grafted on the cornea of which the epithelium had been removed. Keratometry and cycloplegic refraction were performed pre- and post-operatively. RESULTS: Follow-up was between 3 and 13 months (mean, 10 months). All grafts remain clear. The properative mean cylinder was 11.5 diopters and the postoperative mean cylinder was 3.9 diopters. Best corrected visual acuity was improved in 3 eyes. Interface opacification is the main complication, like other forms of epikeratoplasty. Epithelial ingrowth occurred in one eye and the lenticule was replaced. CONCLUSIONS: Epikeratophakia is a simple and effective way for the treatment of severe Terrien's degeneration. This procedure not only increases the corneal thickness, but also hepls the cornea to preserve its transparency, since the Bowman's layer remains intact.
