Abstract

In recent years, corneal refractive surgery continues to develop with becoming to be one of the most prevalent utilizations of correction of many patients and brings about better visual quality for ametropic patients.Meanwhile, some patients are subjected to optical complications, and poor night vision is one of the most serious problems which are complained by sufferers after refractive surgery, such as glare, halo and reduce of contrast sensitivity, and the affective factors include age, pupil diameter, high order aberation, scattering, pre-estimated diopter, corneal healing, individual sensitivity to surgery, which are supposed to attract the attention of the majority of clinicians and researchers, at the same time.Ophthalmic clinical doctors and researchers only fully understand the mechanism of the above factors and explore the corresponding measures in order to purposefully treat these complications.In addition, ophthalmologists should be aware of the interaction of these factors and their relationship with individual sensitivity and explore the impact of postoperative visual impairment and the way to avoid them in clinical practice inorder to improve the visual quality by controlling the postoperative optical complications.

Key words:

Cornea/surgery; Lasers, excimer/therapeutic use; Refractive error/surgery; Postoperative complications; Risk factors; Glare; Visual quality; Night vision quality
