**9. Prophylaxis**

Among the prophylactic measures prior to surgery are the detection of alterations in the eyelids, blepharitis, and anomalies on the ocular surface. During the procedure, appropriate intraoperative measures must be taken, such as correct performance of asepsis, antisepsis, and proper sterilization of the instruments. Any debris present at the flap interface should be removed, as well as any textile material or tab. At the end of surgery, it is recommended to apply one drop of moxifloxacin 5 mg/ml. Regarding post-surgical measures, the time spent wearing contact lenses should be limited, contaminated environments should be avoided, and antibiotics should be administered for a period of 7–10 days, or until the epithelial defect has completely resolved [38].

## **10. Conclusion**

An infection following refractive surgery is considered a potentially devastating complication, which could occur even months after surgery. Antibiotic prophylaxis is thus recommended to provide broad-spectrum coverage with focus on Gram-positive bacteria.
