Currently, the most commonly performed corneal refractive surgery is laser-assisted in-situ keratomileusis (LASIK). Customized forms of LASIK have been developed, which have allowed for improved outcomes and the enhanced correction of higher order aberrations (HOAs). This review discusses one form of custom LASIK, topography-guided LASIK, including factors involved in preoperative planning, and advantages and disadvantages compared with other forms of keratorefractive surgery.
Various treatment-planning approaches addressing discrepancies between the refractive and topographic astigmatic magnitude and axis have been used successfully, although there is debate regarding a superior method in the literature.
There are many forms of custom LASIK, which provide excellent outcomes. Topography-guided LASIK may be of particular use in highly aberrated corneas and may also provide outstanding outcomes in healthy eyes given its emphasis on treating the primary refractive surface of the eye.
目前，最常进行的角膜屈光手术是激光辅助原位角膜磨镶术（LASIK）。已经开发出了定制形式的 LASIK，这使得更好的结果和更高阶像差（HOAs）的增强矫正成为可能。本文讨论了一种定制 LASIK，即基于地形图的 LASIK，包括术前规划中涉及的因素，以及与其他角膜屈光手术形式相比的优缺点。
已经成功使用了各种处理规划方法来解决屈光和地形图散光量和轴之间的差异，尽管文献中存在关于哪种方法更优越的争论。
有许多种形式的定制 LASIK，它们都能提供出色的结果。基于地形图的 LASIK 可能特别适用于高度像差的角膜，并且由于其强调治疗眼睛的主要屈光面，因此在健康眼睛中也能提供出色的结果。
