Abstract：At present, corneal refractive surgery is mainly divided into three categories: superfcial corneal refractive surgery, lamellar corneal refractive surgery and femtosecond laser lens extraction, all of which are widely used in the correction of refractive errors. Although most patients obtain ideal uncorrected distance visual acuity after surgery, the increase of higher-order aberrations often leads to complications such as glare,ghosting,and decreased nightvision.Therearemany factors thatinfluencehigher-order aberrations incornealrefractivesurgery.This review summarizedthetypes ofcornealrefractivesurgeryandthe infuencing factors of higher-order aberrations during corneal refractive surgery including corneal fap/cap, degree of correction, optical zone diameter, optical zone eccentricity, and different excimer laser ablation modes.
