Summary
Excimer laser photorefractive keratectomy (PRK) for myopia can lead to bacterial keratitis. Prompt treatment with antimicrobials is crucial for visual recovery after PRK surgery.
Area of Science:
- Ophthalmology
- Microbiology
Background:
- Myopia correction using excimer laser photorefractive keratectomy (PRK) is a common refractive surgery.
- Bacterial keratitis is a potential sight-threatening complication following ocular procedures.
Observation:
- Two patients developed bacterial keratitis post-PRK for myopia.
- One case involved Staphylococcus epidermidis; the other had a negative culture.
Findings:
- Both patients received topical antimicrobial treatment.
- One patient achieved 20/20 uncorrected visual acuity post-treatment.
- The other patient developed a subepithelial scar, resulting in 20/150 uncorrected visual acuity.
Implications:
- Early diagnosis and aggressive antimicrobial therapy are vital for managing post-PRK bacterial keratitis.
- Visual outcomes can vary, with potential for scarring and persistent visual impairment.
- Further research into preventative strategies and optimal treatment protocols for keratitis after refractive surgery is warranted.
