采用表层角膜镜片术治疗6只无晶体眼和近视眼,1～23个月后将其去除。近视组包括一只以 ArF-准分子激光治疗远视的表层角膜镜片。去除镜片的原因为上皮损害,受眼角膜水肿和过矫。表层镜片的基质显示中心区的纤维结构正常,角质细胞稀少。电子显微镜检查显示胞浆中的细胞器和细胞核保存完整,未见淋巴细胞和其他单核细胞。6只境片的前弹力层均正常,未见前弹力层破裂,仅有轻度波状弯曲,偶见局部有皱褶。角膜上皮有轻度异常,厚度有变化。周边切口区域基质层及上皮异常较为明显。
Six cases of aphakia and myopia were treated with surface corneal ophthalmoscopy and removed after 1 to 23 months. The myopia group includes a superficial corneal lens treated with ArF-excimer laser. The reason for removing the lens is epithelial damage, corneal edema and overcorrection. The surface of the lens shows the central lens of the normal fiber structure, keratinocytes scarce. Electron microscopy showed that the organelles and nuclei in the cytoplasm were intact without lymphocytes and other monocytes. The 6 frontal elastic layer are normal, no front elastic layer rupture, only slight wavy bending, occasionally local wrinkles. Corneal epithelial mild abnormalities, changes in thickness. Peripheral incision area of the stromal and epithelial abnormalities more obvious.
