AIMS To report the clinical findings and visual outcome of patients with extended wear contact lens (EWCL) related bacterial keratitis.

METHODS 11 cases with EWCL related bacterial keratitis were included. Corneal scrapings were obtained for cytology and cultures.

RESULTS Nine patients had unilateral bacterial keratitis and two patients showed bilateral involvement. Corneal scrapings revealedPseudomonas aeruginosa in seven patients, Staphylococcus aureus coagulase positive in one patient, and Staphylococcus epidermidisin three patients.

CONCLUSION EWCLs may be associated with bacterial keratitis and may result in visual loss. Dispensing contact lenses by optometrists should be performed in consultation with ophthalmologists.
