Comparison of small incision lenticule extraction and femtosecond laser assisted LASIK for myopia

Abstract

AIM: To compare the postoperative visual outcomes of VisuMax small incision lenticule extraction(SMILE)and femtosecond laser assisted LASIK(FEMTO LASIK)for myopia. METHODS:Eighty-tree eyes(42 patients)underwent VisuMax SMILE and 94 eyes(47 patients)received FEMTO LASIK to correct myopia were comprised. The safety, efficacy, predictability, stability and adverse events were assessed preoperatively and 1d, 1 week, 1 month, 3 months postoperatively. RESULTS: At 3 months, the mean safety index was 1.10±0.16 in the SMILE group and 1.09±0.16 in the FEMTO LASIK group; the mean efficacy index was respectively 1.10±0.16 and 1.08±0.12; Spherical equivalent(SE)was respectively 0.11±0.23D and 0.08±0.25D within ±1.00D of the targeted SE correction in 82 eyes(98.8%)of the SMILE group and 91 eyes(96.8%)of the FEMTO LASIK group and SE within ±0.50D in 73 eyes(88.0%)of the SMILE group and 78 eyes(83.0%)of the FEMTO LASIK group. There were no significant complications in both groups. CONCLUSION: SMILE and FEMTO LASIK have equal safety, efficacy, predictabilityand stability in the treatment of myopia.
