title: Endophthalmitis caused by Staphylococcus hominis and two different colonies of Staphylococcus haemolyticus after cataract surgery.
abstract: OBJECTIVE
  To describe a case of endophthalmitis after cataract surgery caused by Staphylococcus hominis and two separate colony types of Staphylococcus haemolyticus.
  
  
  METHODS
  Retrospective chart review including ophthalmic examination, intraocular biopsy and cultures, and anterior segment photography.
  
  
  RESULTS
  A patient presented with endophthalmitis 1 month after cataract surgery. The patient underwent pars plana vitrectomy with vitreous fluid, aqueous fluid, and lens capsule biopsy with injection of intravitreal antimicrobials with full resolution of the infection. Cultures isolated grew S. hominis and two different colonies of S. haemolyticus, all sensitive to vancomycin.
  
  
  CONCLUSIONS
  To the best of the authors' knowledge, this is the first case of endophthalmitis due to lens capsule seeding from three different types of bacteria, S. hominis and two different colony types of S. haemolyticus. Prompt diagnosis and treatment can be associated with good visual outcomes.
