[Clinical application of visual quality analysis in cataract patients].

ABSTRACT

Cataract is a major cause of blindness and vision impairment disease, and the main therapy for cataract is operation. For improving the postoperative efficiency, cataract surgery has gradually transformed from traditional restorative surgery to refractive surgery with modern technique. Visual quality is one of the crucial indicators for assessing imaging quality and surgical efficiency in cataract patients. Although several instruments are available, each has its advantage and disadvantage. In the clinic, the optimum visual quality analysis methods should be selected according to the principle, function and clinical significance to meet the practical needs of different cataract patients.
