   Abstract Suspected of infection in 31 cases of soft contact lens wearens were studied for microorganisms by smears and cultures. Resulted 22 cases of positive cultured (70.97%) and 19 cases of them were found gram negative bacilli (86.36%). Among these cases, were proved by culture to be Psueodomonas in 14 cases (63.64%). Surprisingly the second cause of contact lens infection next to pseudomonas was bacterial flora of the eye and
also surprisingly we found no Psueodomonas among all four cases of infected extended soft contact lens wearers.
