没那么恐怖吧！术前医生会检查你眼部各项指标是不是符合手术要求，有没有疾病和炎症，符合条件才能做。比如角膜太薄就不能做。

It's not so bad! Prior to surgery the doctor will examine all the different parts of your eyes and see if they're suitable for surgery, or whether or not you have any diseases or inflamation. Then, they'll only do the surgery if the conditions are right. For example, if your cornea is too thin, they can't do it.
