The prevalence of microbioogic flora was determined in a convenience sample of contact lens wearers at the Puerto Rico Medical Center, ophthalmology clinics obtaining cultures from the conjunctival fornices. Gram positive bacterial prevalence was 100% in the control group, as well as in rigid gas permeable lens wearers. In the soft contact lens group, gram positive bacterial prevalence was 94.7%. On the other hand prevalence of Gram negative bacteria is null in the soft contact lens wearer population, being only 2.5% in control group, and 45.5% for Rigid Gas Permeable wearers. These contact lens wearers were using different disinfection systems.
