球形角膜为全部角膜包括角膜缘部都向前膨隆,全部角膜明显变薄,其厚度可减到正常角膜的三分之一。但有时圆锥角膜也可以弥漫的变薄和隆起而转变成球形角膜,在同一家族中的不同成员可分别患有圆锥角膜和球形角膜,故认为两者属同一类疾病。因球形角膜整个都很薄故不可能施行穿透性角膜移植术,作者对3例球形角膜施行板层角膜移植术,收到良好效果。方法如下:用9-11mm The cornea of ​​the cornea, including the corneal limbus, bulges forwardly, with the entire cornea becoming significantly thinner and its thickness reduced to one-third of that of the normal cornea. But sometimes the keratoconus can also be thinning and swelling and into spherical cornea, in the same family of different members may suffer from keratoconus and spherical cornea, so that both belong to the same type of disease. Penetrating keratoplasty was impracticable because the entire cornea was thin, and the authors received lamellar keratoplasty in 3 corneas, receiving good results. The method is as follows: Use 9-11mm
