The multiple radial stromal deep corneal incisions placed in radial keratotomy (RK) lead to higher-order aberrations and pose a surgical challenge to performing any further corrective procedure on the cornea because of fear of inducing an incisional dehiscence. A method to perform pinhole pupilloplasty (PPP) in the setting of previous RK is presented. Application of pinhole optics by performing PPP leads to significant improvement in image quality and helps to optimize visual potential in post-RK cases.
在放射状角膜切开术（RK）中进行多个放射状基质深层角膜切口会导致高阶像差，并由于担心引起切口裂开，对角膜进行任何进一步的矫正手术都构成了手术挑战。本文介绍了一种在既往 RK 基础上进行小孔瞳孔成形术（PPP）的方法。通过 PPP 应用小孔光学，可显著改善图像质量，并有助于优化 RK 术后的视觉潜力。
