Effect of the Vectorial Difference Between Manifest Refractive Astigmatism and Anterior Corneal Astigmatism on Topography Guided LASIK Outcomes

摘要

PURPOSE: To characterize the preoperative vectorial difference between manifest refractive astigmatism and anterior corneal astigmatism, termed ocular residual astigmatism (ORAL, and to investigate its influence on topography-guided laser in situ keratomileusis (LASIK) outcomes.
