In vitro colonization of hydrophilic contact lenses by Aspergillus niger

In vitro colonization of hydrophilic contact lenses by Aspergillus niger was investigated. Five strains of the fungus, four polymers, two culture media and four incubation periods were considered for analysis. Only the 2700 strain colonized the lenses. The degrees of adhesion and invasion varied significantly according to the characteristics of the culture under investigation.
