Multidrug-Resistant Pseudomonas aeruginosa Keratitis

Lubricant ointment use, a compromised ocular surface, and bandage contact lens use are associated with MDR-PA keratitis. Preservative-free lubricant ointment may act as a source or reservoir of infection. Outcomes are worse in MDR-PA keratitis compared with drug-sensitive P. aeruginosa keratitis.
