**11. Conclusion**

We describe our experience in patients who developed keratitis caused by nontuberculous mycobacteria. As the most common cause of post-LASIK keratitis is NTM, a greater degree of suspicion, recognition of typical clinical course and presentation, and knowledge of simi‐ lar cluster of NTM keratitis prompts rapid institution of appropriate antibiotic therapy, granting this cases with a better prognosis in comparison with those of late diagnosis. Anti‐ biotic resistance continues to be an emerging problem, thus a limitation in the coverage of this pharmacological agents exists. We emphasize the need for vigilance in the follow-up of patients. Appropriate adjustment of antimicrobial therapy may be required based on cul‐ tures and sensitivity tests when atypical mycobacteria are responsible for corneal infection. We believe that fourth-fluoroquinolones adequately combined with first-line antibiotics con‐ stitute the best option so far to treat keratitis caused by atypical mycobacteria.
