Comparison of visual and refractive outcomes between femtosecond laser-assisted in situ keratomileusis (FS-LASIK) and photorefractive keratectomy (PRK): a long-term outcomes analysis

Aim: We aimed to compare the results of photorefractive keratectomy (PRK) and femtosecond-assisted laser in situ keratomileusis (FS-LASIK) procedures treatment myopia myopic astigmatism.
 Material Method: Seventy eyes 35 patients with and/or astigmatism who had undergone PRK procedure were compared retrospectively 70 FS-LASIK procedure. 
 Results: All completed 2-year follow-up period. With respect age sex, groups comparable. The differences uncorrected distance visual acuity (UDVA), corrected (CDVA), spherical equivalent significantly better than at 6- 24-month visits. similar values safety index, efficacy predictability 6 24 months postoperatively. No significant complications observed neither during Conclusion: Both seem equally effective options for correction astigmatism. However, provided slightly refractive outcomes
