Comparison of effects of SMILE and FS-LASIK in treatment of patients with refractive myopia
Objective:To compare effects of small incision lenticule extraction(SMILE)and femtosecond laser in situ keratomileusis(FS-LASIK)in treatment of patients with refractive myopia.Methods:The clinical data of 106 patients with refractive myopia admitted to this hospital from June 2021 to July 2023 were retrospectively analyzed.According to different surgical methods,they were divided into control group and observation group,53 cases in each group.The control group was treated with FS-LASIK,while the observation group was treated with SMILE.The clinical efficacy,the ophthalmic indexes(naked visual acuity,intraocular pressure)levels,the spherical equivalent refraction level,and the incidence of complications were compared between the two groups before and after the surgery.Results:There were no significant differences in the total effective rate and the incidence of complications between the two groups(P＞0.05).7 days and 1 month after the surgery,the intraocular pressure levels of the two groups were lower than those before the surgery,but that in the observation group was higher than that in the control group 7 days after the surgery;the naked visual acuity of the two groups were higher than those before the surgery,and that of the observation group was higher than that of the control group 7 days after the surgery;and the differences were statistically significant(P＜0.05).Further,3 and 7 days after the surgery,the spherical equivalent refraction levels of the two groups were lower than those before the surgery,that in the observation group was lower than that in the control group the 3 days after the surgery,and the differences were statistically significant(P＜0.05).Conclusions:SMILE can improve the early postoperative intraocular pressure,the naked visual acuity and the spherical equivalent refraction in the patients with refractive myopia.It is superior to FS-LASIK treatment,but the total effective rate and the incidence of complications of the two treatments are equivalent.
