Summary
Microbial keratitis is a serious complication following laser in situ keratomileusis (LASIK) surgery. Early detection and aggressive treatment are crucial for managing this sight-threatening condition after LASIK.
Area of Science:
- Ophthalmology
- Microbiology
Background:
- Laser in situ keratomileusis (LASIK) is a common refractive surgery.
- Microbial keratitis is a potential complication following LASIK.
Purpose of the Study:
- To review the existing literature on microbial keratitis after LASIK.
- To understand the causative agents, presentation, and management of post-LASIK microbial keratitis.
Main Methods:
- Literature review of reported cases of microbial keratitis post-LASIK.
- Analysis of causative organisms, timing of onset, and treatment strategies.
Main Results:
- Forty-one cases of microbial keratitis post-LASIK were reported.
- Infectious agents included bacteria, atypical mycobacteria, fungi, and viruses.
- Most infections were acquired intraoperatively or via postoperative contamination, presenting within 72 hours.
Conclusions:
- Microbial keratitis is a sight-threatening complication of LASIK.
- Aggressive management, including fortified antibiotics and flap irrigation, is essential.
- Most patients achieve good visual outcomes with prompt treatment.
