Post Laser Vision Correction Infectious Keratitis
• Infectious keratitis following laser vision correction
as reported by the 2008 American Society of
Cataract and Refractive Surgery (ASCRS) survey was
19 of 20,941 eyes or 0.09%.
• The most commonly cultured organism in this series
was methicillin-resistant Staphylococcus aureus
(MRSA).
• One case definitively resulted from a fungal infectionSolomon R, Donnenfeld E, Holland E, Yoo S, Daya S, Guel J, Mah F, Scoper S, Kim T.

Case Presentation• 24-year old female -1.25D sphere in both eyes
• Her exam, pachymetry and corneal tomography were normal
• Her history included prior right V1 dermatome herpes zoster
without ophthalmic involvement
• Treated with wavefront-optimized femtosecond-LASIK on the
WaveLight FS-200 and Allegretto Eye-Q laser platform (Alcon, Fort
Worth, TX, USA)
• She had an uneventful procedure and was started on ciprofloxacin
0.3% (Ciloxan®) and dexamethasone 0.1% drops four times daily
each.
• On post-op day one, UDVA was 20/15 in each eye. Her exam was
unremarkable
Case Presentation
• During the week prior to this case, a new wall was
built within the refractive suite waiting area, which
was not directly continuous with the laser suite
• However, the day prior to the case, construction
workers had removed some ceiling tiles in the
laser suite in preparation for the upcoming
construction and removal of an internal wall
Postoperative Day 2• Patient presents with pain and
decreased vision• UDVA OD 20/50
Clinical Plan• Clinical suspicion for fungal keratitis was high
• The flap was lifted and a gelatinous branching infiltrate was seen,
extending superficially into the flap and posteriorly into the stromal bed
• Cultures were obtained and the interface was irrigated extensively
• Because the infiltrate penetrated into the flap stroma, and due to the
rapid progression (< 24 hours) of a presumed of fungal keratitis, a
