Comparison of clinical outcomes of implantable collamer lens versus femtosecondlaser in situ keratomileusis and small incision lenticule extraction for moderate-to-high myopia and myopic astigmatism correction

Purpose: To compare safety, efficacy, stability, and predictability of implantable collamer lens (ICL) with femtosecond-laser in situ keratomileusis (FS-LASIK) or small incision lenticule extraction (SMILE) for the correction moderate-to-high myopia/myopic astigmatism.
 Study design: We retrospectively collected data from patients astigmatism (spherical equivalent [SE] ≥ −3.00 diopters [D]) who underwent ICL (48 eyes), FS-LASIK (36 SMILE (86 eyes) at Hai Yen Eye Center October 2016 to February 2018.
 Materials methods: The Wilcoxon Mann-Whitney U test was used pre- postoperative patients’ characteristics FS-LASIK. Generalized linear models unstructured correlation matrix robust standard errors were analyze efficacy safety indices; logistic regression cylinder predictability.
 Results: After controlling age, preoperative SE, corrected distance visual acuity (pCDVA), had significantly lower indices (Coefficient = −0.04, 95% CI −0.07–−0.01) −0.10, −0.20–−0.01) than did ICL, while not different −0.02, −0.06–0.02 Coefficient −0.01, CI= −0.10–0.09, respectively). SEswere stable over 12 months after surgery. However, SMILE, SEs decreased compared 6 percentage eyes that target within ±0.5 D those (OR 0.14, 0.02–0.85), pCDVA.
 Conclusion: For astigmatism, seems perform better
