Superior visual quality not only means normal visual acuity, also includes normal contrast sensitivity, color vision, visual field and binocular vision. The concept of wave-front aberration and its correction technique have been introduced into the ophthalmology in China, and play an important role in finding and resolving the problems related to the visual quality. However, the concept and knowledge of the wave-front aberration does not get popularization in Chinese ophthalmologists. The research and clinical application is scanty. The status should be changed as quickly as possible.
