Therapeutic effects of three refractive surgeries on refractive errors

AIM:To observe the therapeutic effects of standard laser in situ keratomileusis(LASIK),wavefront-guided LASIK(WF-LASIK)and small incision lenticule extraction(SMILE)on refractive errors.METHODS:This study retrospectively analyzed 97 patients(194 eyes)with refractive errors admitted to the hospital between March 2020 and March 2021.They were divided into LASIK group(28 cases,56 eyes),WF-LASIK group(32 cases,64 eyes)and SMILE group(37 cases,74 eyes)according to the surgical method.The uncorrected visual acuity(UCVA),diopter,high-order aberrations,tear film break-up time(BUT)and tear secretion function(SⅠt)were observed before and after operation,and related complications were recorded.RESULTS:The UCVA,spherical diopter,cylindrical lens diopter and spherical equivalent were similar in the 3 groups at 1 and 3mo after operation(all P>0.05).The spherical aberrations of LASIK group,WF-LASIK group,and SMILE group at 1 and 3mo after operation decreased in order(all P<0.05).The horizontal coma and vertical coma of LASIK group and SMILE group at 1 and 3mo after operation were greater than those of WF-LASIK group(all P<0.05).The total high order aberrations of LASIK group at 1 and 3mo after operation were significantly greater than those of the other two groups(all P<0.05).BUT and SⅠt of SMILE group at 1 and 3mo after operation were significantly better than those of the other two groups(all P<0.05),without significant difference between WF-LASIK group and LASIK group(all P>0.05).The total incidence rates of complications in the 3 groups were close(P>0.05).CONCLUSION:All of LASIK,WF-LASIK and SMILE can improve vision of patients with refractive errors.However,patients treated with WF-LASIK have the best visual quality after operation,and those treated with SMILE can obtained better tear film stability after operation.
