Higher-order aberration correction in abnormal eyes can result in significant vision improvement, especially in eyes with abnormal corneas. Customized optics such as phase plates and customized contact lenses are one of the most practical, nonsurgical ways to correct these ocular higher-order aberrations. We demonstrate the feasibility of correcting higher-order aberrations and improving visual performance with customized soft contact lenses in keratoconic eyes while compensating for the static decentration and rotation of the lens. A reduction of higher-order aberrations by a factor of 3 on average was obtained in these eyes. The higher-order aberration correction resulted in an average improvement of 2.1 lines in visual acuity over the conventional correction of defocus and astigmatism alone.
在异常眼中进行高阶像差校正可显著改善视力，尤其是在角膜异常的眼中。定制光学器件，如相位板和定制隐形眼镜，是校正这些眼部高阶像差最实用的非手术方法之一。我们证明了使用定制软性隐形眼镜校正高阶像差并改善圆锥角膜患者视觉性能的可行性，同时补偿镜片的静态偏心和旋转。这些眼睛平均高阶像差降低了3倍。与仅进行传统的散焦和散光校正相比，高阶像差校正使视力平均提高了2.1行。
