角膜云翳、斑翳（二）
3、角膜移植，至今为止大多数仍然采用穿透性角膜移植，即钻除受体角膜中央区的全层角膜，移植组织结构正常并含一定活的内皮细胞数量的全层健康供体角膜。传统的板层角膜移植，是在切除一定厚度的受体角膜组织之后，再将组织结构正常、厚度相当的供体角膜移植到相应的受体基质床上，尽管它也能一定程度提高角膜的透明性，但是术后常在受体角膜基质床与供体角膜（基质）内表面之间形成层间疤痕，恢复角膜透明性的效果往往不理想，因此主要用于修补及重建角膜完整性的目的，属于治疗性或结构性角膜移植。穿透性角膜移植在恢复角膜透明性和提高视力方面的效果是可喜的，但也存在诸多缺点，如为开放眼内结构的手术、术中存在损伤眼内组织的危险、术后存在免疫排斥反应并导致植片失败的可能等。临床研究表明，既使在不伴有新生血管侵入的原发角膜疾病如圆锥角膜的眼上进行穿透性角膜移植时，术后也存在不低的植片排斥反应发生率。 4、部分患者角膜移植后容易出现排异反应：角膜基质层存在新生血管，因为新生血管使免疫细胞更容易到达移植片，识别并攻击异体抗原。大的移植片因为携带的有效抗原强，并且靠近患者角膜缘，所以易发生排斥反应。患者自身敏感性较高，也易发生排斥反应。其他一些因素如突发性的炎症、眼部充血刺激等等也可能诱发排斥反应。 5、手术费用及后期抗排异治疗费用普遍较高。魏氏中医眼科的辨证施治：
魏氏中医眼科发展至今已有百余年的悠久历史，四代人传承所积累的丰富的临床治疗经验，对于治疗细菌性、病毒性、霉菌性、真菌性、外伤性等因素引起的角膜云翳、角膜斑翳治疗疗法独到，费用较低。百年来人民群众收益广泛。 在大多数人的印象中，中药熬制过程繁琐、口感不好、疗效较慢，这其实是主观印象。要区分患的是什么疾病和病情的轻重程度及医生水平的高低直接决定中医中药发挥的功效快慢。举个很简单的例子，中医治病其实很像两军对决，胜败并非完全取决于单纯在于兵力，关键在于指挥决策的人，其实只要综合全局考虑问题、打胜仗并不困难。魏医生四十年来通过临床治疗的患者疗效经验总结：大多数患者角膜云翳视力不同程度的受到障碍，一般灵活运用家传辨证施治退翳法，坚持两个疗程治疗裂隙灯下检查云翳便会比较明显的吸收消散，角膜呈现较明显的的通透度改善。根据病情遵医嘱坚持治疗基本才能逐渐使得角膜翳逐渐消退。角膜逐渐恢复清澈透亮。属于角膜斑翳,并贯穿至角膜深层,并且患病时间较长，属于“老翳”面积范围大的患者临床观察连续治疗两个疗程左右者，大多数老翳裂隙灯下观察出现不同程度角膜翳范围缩小，角膜翳部分部位逐渐光滑通透。再者临床观察大多数角膜白斑患者，虽然瘢痕贯穿全层，时间较久，范围较广者遵医嘱连续治疗2个疗程裂隙灯下检查角膜也会出现不同程度变化，角膜翳范围不同程度缩小，改善，角膜不同程度通透。有图有对比才能说明一切。实例说明介绍几位不同情况的云翳、斑翳、白斑患者的治疗期间的对比照片让大家更加直观的了解魏氏中医眼科的中医眼科技术实力：
