Life quality of vision after corneal refractive surgery

Life vision is the visual ability during daily life and work. Far and near visual acuities are needed for good life vision, but visual balances including binocular balance, day and night balance, and far and near balance, are more important. The golden standard of evaluating corneal refractive surgery is not only the anticipated corrected visual acuity, but also the good life quality of vision. Higher quality corneal refractive surgery includes three major parts: excellent excimer laser device; favorable surgical environment and consummate surgical technique; customized analysis and surgical design. These three interrelate with each other and are equally important. (Ophthalmol CHN, 2006, 15:161-163 )
