Abstract
There have been numerous reports regarding the occurrence of keratitis in
patients with soft contact lenses, but few reports in patients with rigid gas
permeable contact lenses. To the best of our knowledge, the occurrence of
infection associated with three species of pathogens has never been reported.
Here, we describe a patient who exhibited refractory painless keratitis caused
by three pathogens (Staphylococcus epidermidis,
Acanthamoeba, and herpes simplex virus) and summarize
similar reports published at multiple centers worldwide, with the aim of
providing guidance for clinicians who might encounter mixed-type corneal
infections. We describe the results of many ophthalmologic and laboratory
investigations, which guided our treatment selection. We achieved good treatment
efficacy, such that the patient exhibited a corrected visual acuity of 20/20 in
the affected eye after a series of treatments, including curettage of ulcer
lesions. Corneal infections caused by multiple pathogens are challenging in
clinical practice. This summary of our experience in patient diagnosis and
treatment can help clinicians to achieve a favorable prognosis in treatment of
future patients.
