瑞士巴塞尔大学眼科系Studer H教授及其工作团队最近在Sensors (Basel).上发表了他们的最新研究成果:基于光学定制的新型激光屈光手术治疗可以改善老花眼的临床治疗效果。

激光辅助原位角膜磨镶术(LASIK)是经过验证的、适于角膜屈光手术的治疗方法。但此项治疗技术会诱发高阶光学畸变,这也是为什么该方法很少用于治疗老花眼(老年相关近视力丧失)的主要原因。

在Studer H教授最近的这项研究中,新颖的定制算法被用于设计多焦点消融图案,从而最小化诱导的光学像差。作者们利用这个算法去治疗36个老花眼受试者。 治疗结果显示,手术后6个月,大多数老花眼受试者从视力差到未矫正视力20/20甚至于达到更加视力水平:近视(78%),中间(92%)和远视(86%)。 所有受试者的距离和中度视力均为20/25或更好,多数(94%)近视力较好。

作者认为,即使需要进一步的研究,但他们的研究结果可以说明他们所采用的基于光学定制的新型激光屈光手术方法是一种安全的、可靠的和可预测的老花眼屈光手术治疗方法。
