Abstract
Objective To observe the influence of scotopic pupil diameter on visual quality after small incision lenticule extraction(SMILE)under large optical zone lens design.Methods Retrospective analysis of 28 patients(56 eyes)who underwent SMILE surgery in the Fifth Affiliated Hospital of Guangzhou Medical University from December 2021 to April 2022.Large optical zone(diameter ≥6.5 mm)was used in all patients.According to the relationship between the surgical optical zone and the scotopic pupil,30 eyes in group A(the optical zone is smaller than the diameter of the scoto-pic pupil)and 26 eyes in group B(the optical zone is larger than or equal to the diameter of the scotopic pupil).All pa-tients were measured for spherical degree,cylindrical degree,spherical equivalent(SE)degree,uncorrected distance visu-al acuity(UCVA),best corrected visual acuity(BCVA),all levels of high-order corneal aberration,point scatter function(PSF)before and at 1 and 3 months after the surgery.Results There were no significant differences in central corneal thickness(CCT),spherical degree,cylindrical degree,spherical equivalent degree,BCVA,total higher-order aberration,spherical aberration,coma,trefoil and point scatter function(PSF)between the two groups preoperative(all P＞0.05).However,the optical zone and scotopic pupil diameter,optical zone minus scotopic pupil diameter value differences were statistically significant(all P＜0.05).The spherical degree and △ spherical aberration in group A were higher than those in group B at 1 month after the operation(P＜0.05),and the △ spherical aberration in group A was higher than that in group B at 3 months after the operation(P＜0.05).However,there were no significant differences in spherical degree,cylindrical degree,spherical equivalent degree,UCVA and BCVA(P＞0.05).There was no significant difference in sub-jective visual quality parameters(night glare,fog,halo,night vision,dryness,foreign body sensation,vision fluctuation,double vision and satisfaction)among three groups at 3 months after the opertion.Conclusions When a large optical zone(diameter≥6.5 mm)is used in SMILE surgery,the scotopic pupil diameter is larger than the optical zone,which will only increase the change of postoperative spheri-cal aberration,and has no obvious influence on refractive power,vision and subjective visual quality after surgery,but still a good visual quality after surgery can be obtained.关键词
