With the improvement of cataract examination methods, intraocular lens (IOL) design and process, surgical equipments and techniques, cataract surgery was gradually developed from vision rehabilitation to refractive surgery.Therefore, the assessment of visual quality is getting more attention.Clinically, in addition to the extension of concept of visual acuity, contrast sensitivity function (CSF), modulation transfer function (MTF), point spread function (PSF), wavefront aberration and scattering index are also used, with a view to making a comprehensive assessment of visual quality of cataract patients preoperatively and postoperatively.Ophthalmologists should pay attention to the methods and results of evaluation on the visual quality, to provide support for the design of personalized surgery and the improvement of visual quality.
