| 摘要：随着屈光手术的发展，过去人们所追求的单纯裸眼视力的提高逐渐被追求视觉质量的提高所代替。LASIK 术后患者低阶像
差减小，高阶像差进一步增加，虽然裸眼视力提高，但是对比敏感度下降，尤其是暗环境下和有眩光时视觉质量不能达到理想效
果，因为高阶像差是影响视网膜成像的重要因素，对比敏感度是评价视网膜成像质量好坏的重要指标之一，所以探讨不同成分高
阶像差以及它们之间适当组合对视觉质量的影响和LASIK 术后各频段对比敏感度的变化，研究各项高阶像差与对比敏感度之间
的关系可以为临床外科屈光医生提供一定的理论指导，进而解决LASIK 术后的眩光、星形放射、暗视力差等问题。本文通过概括
LASIK 术后高阶像差和对比敏感度的变化，对它们之间关系的研究现状和进展作一综述。 |

| ABSTRACT:With the development of refractive operation, instead of the past people pursuit of simple visual acuity improved
gradually by the pursuit of improving the quality of vision. LASIK patients with low order aberration decreased, high order aberration
increased further, the visual acuity increased, but the decrease of contrast sensitivity, especially the dark environment and glare visual
quality can not achieve the desired effect, because the high order aberration is an important factor affecting the retinal imaging, contrast
sensitivity is one of important index to evaluate the quality of retina imaging, so the study of higher order aberrations between different
components and their appropriate combination effects on visual quality and changes in contrast sensitivity of each band after LASIK，
study on the relationship between higher order aberrations and contrast sensitivity can provide some theoretical guidance for clinical
surgical refractive doctor, and then solve the glare, the star radial, poor dark adaptation problems after LASIK. This paper summarizes
changes of the high order aberration and contrast sensitivity after LASIK, current status and progress of research on the relationship
between themare reviewed. |
