Abstract

This paper presented a patient who developed Pseudomonas keratitis followed by overnight wear
and two contact use in the left eye in an elderly patient. Risk factors were identified including old age,
overnight wear, and internet contact lens purchase. Gram negative bacilli were identified from patient’s
corneal specimen. Cultures of the corneal sample yielded growth of Pseudomonas aeruginosa. The
clinical sign and symptom improved after topical fortified gentamicin and levofloxacin were prescribed.
