The broad acceptance of "spot scanning" or "flying spot" excimer lasers in the last decade has enabled the domination of corneal ablative laser surgery over other refractive surgical procedures for the correction of hyperopia, hyperopic and mixed astigmatism. This review outlines the most important reasons why the ablative laser correction of hyperopia, hyperopic and mixed astigmatism for many years lagged behind that of myopia. Most of today's scanning laser systems, used in the LASIK and PRK procedures, can safely and effectively perform low, moderate and high hyperopic and hyperopic astigmatic corrections. The introduction of these laser platforms has also significantly improved the long term refractive stability of hyperopic treatments. In the future, further improvements in femtosecond and nanosecond technology, eye-tracker systems, and the development of new customized algorithms, such as the ray-tracing method, could additionally increase the upper limit for the safe and predictable corneal ablative laser correction ofhyperopia, hyperopic and mixed astigmatism.
在过去十年中，“光斑扫描”或“飞点”准分子激光被广泛接受，这使得角膜切削激光手术在矫正远视、远视散光和混合散光方面优于其他屈光手术。本文综述了多年来远视、远视散光和混合散光的切削激光矫正落后于近视矫正的最重要原因。如今，用于LASIK和PRK手术的大多数扫描激光系统都能安全有效地进行低、中、高度远视和远视散光矫正。这些激光平台的引入也显著提高了远视治疗的长期屈光稳定性。未来，飞秒和纳秒技术、眼动追踪系统的进一步改进，以及诸如光线追踪法等新的定制算法的开发，可能会进一步提高远视、远视散光和混合散光的安全可预测角膜切削激光矫正的上限。
