对30例（60只眼）因无晶状体眼（20例）或圆锥角膜（10例）而接受单侧表面角膜镜片术的患者进行了角膜敏感性测试。术后恢复时间为2个月至21个月（平均10个月）。我们的研究结果表明，与周围宿主角膜和对侧对照角膜相比，角膜镜片术的角膜表面感觉相对迟钝。然而，11例随访超过1年的患者的角膜敏感性高于19例术后恢复不到1年的患者。在两个非人灵长类动物的神经细胞的组织学研究结果表明稀疏的上皮轴突终端。宿主角膜神经似乎通过上皮内延伸和穿透浅层角膜切除术瘢痕来支配角膜上皮。
Corneal sensitivity was tested in 60 eyes of 30 patients who underwent unilateral epikeratophakia for the correction of aphakia (20 patients) or keratoconus (10 patients). Postoperative recovery time ranged from 2 months to 21 months (mean: 10 months). Our results indicate a relative hypesthesia of the epikeratophakia lenticule when compared with the peripheral host cornea and contralateral control cornea. However, corneal sensitivity tested in 11 patients with more than 1 year follow-up was increased compared with the sensitivity of 19 patients whose postoperative recovery was less than 1 year. Histopathologic findings in two lenticules from a nonhuman primate demonstrated sparse epithelial axon terminals. Host corneal nerves appear to innervate the lenticules by intraepithelial extension and by penetration of the superficial keratectomy scar.
