  • Title: Biofilm formation by Enterococcus faecalis on intraocular lens material.
    Author: Kobayakawa S, Jett BD, Gilmore MS.
    Journal: Curr Eye Res; 2005 Sep; 30(9):741-5. PubMed ID: 16146919.
    Abstract:
    PURPOSE: To compare biofilm formation by Enterococcus faecalis on different intraocular lens (IOL) materials. METHODS: E. faecalis biofilms were cultivated on disks of IOL material (silicone, PMMA [polymethylmethacrylate], or acrylic). Biofilms were stained with crystal violet (CV), which served as an index of biofilm formation. The bacterial population was enumerated after biofilm homogenization. Biofilms were also examined by confocal microscopy. RESULTS: At 24 hr, there was no significant difference in biofilm formation, or the population within biofilms, among the three materials tested. However, after 48 and 72 hr, it was observed that silicone supported the least amount of biofilm formation (p < 0.05); biomass on PMMA and acrylic IOLs continued to increase, with acrylic demonstrating the greatest amount of stainable biofilm (p < 0.0005). The population on PMMA was significantly greater than the other IOL materials (p < 0.005). Confocal microscopy confirmed the lack of biomass on silicone. CONCLUSIONS: Among three IOL materials, E. faecalis biofilms formed more readily on PMMA and acrylic compared to silicone.
