Summary
Delayed onset microbial keratitis occurred in a LASIK patient due to Bacillus megaterium. Prompt antibiotic therapy led to excellent visual recovery, highlighting the importance of culturing the lamellar interface.
Area of Science:
- Ophthalmology
- Microbiology
Background:
- Laser-Assisted In Situ Keratomileusis (LASIK) is a common refractive surgery.
- Complications, though rare, can occur post-LASIK.
Observation:
- A 23-year-old male presented with delayed onset lamellar keratitis two weeks post-LASIK.
- Initial symptoms suggested infection, prompting LASIK flap elevation and cultures.
Findings:
- Bacillus megaterium was identified and sensitive to all tested antibiotics.
- Aggressive antibiotic treatment resulted in rapid symptomatic relief and a final visual acuity of 20/15.
Implications:
- This case highlights an unusual presentation of microbial keratitis post-LASIK.
- Culturing the lamellar interface is crucial for suspected microbial keratitis after refractive surgery.
- Preparedness for aggressive antibiotic therapy is essential.
