title: Postoperative low-grade endophthalmitis caused by biofilm-producing coccus bacteria attached to posterior surface of intraocular lens.
abstract: We report a case of low-grade inflammation that developed in the anterior segment after cataract extraction with intraocular lens (IOL) implantation. The 57-year-old patient complained of blurred vision 2 weeks after phacoemulsification and IOL implantation in the right eye. Slitlamp biomicroscopy showed many nonpigmented keratoprecipitates. After antibiotic therapy failed, the IOL was removed and aqueous collected. Scanning electron microscopy of the IOL demonstrated many biofilm-producing cocci with slime on the IOL, and aqueous smears showed gram-positive cocci. Two weeks after removal of the IOL, the inflammation disappeared.
