Pseudomonas corneal ulcer after use of extended-wear rigid gas-permeable contact lens.

We report a bacterial corneal ulcer that occurred in a patient who had worn extended-wear rigid gas-permeable contact lenses on a 1-week cycle for 9 months. Pseudomonas aeruginosa was cultured not only from the corneal ulcer but also from the contact lens solutions, suggesting that the patient had been noncompliant with care procedures. To our knowledge, this is the first report of a bacterial corneal ulcer associated with use of a rigid gas-permeable contact lens on an extended-wear basis.
