[Update the concepts on visual correction and enhance the visual quality after corneal refractive surgery]

In recent years, new technologies and ideas of modern ophthalmology and optometry have emerged. Based on the wavefront technology and its derivatives, the traditional concepts of refractive errors and vision correction have been redefined and supplemented. Human optical quality can be evaluated effectively and objectively. Moreover, the studies about the wavefront vision correction have shown preferable vision correction results. Application of these modern methods of wavefront refraction and correction offers important opportunities for better optical quality and visual performance in corneal refractive surgery. It also provides a foundation for creating novel clinical diagnosis and treatment options in vision correction.
