Microbial factors in contact lens fitting

As contact lens practitioners, optometrists work in a nonsterile environment and on a nonsterile part of the human body. Our report describes 10 cases of eye infection related to contact lens wear. Practitioners need to be aware of the problems which can occur when a thoroughly sterilized contact lens is placed on an unsterile and biologically complex eye. We recommend taking swabs of the conjuctiva in all eyes where ocular inflammation is present. In those areas in which the professions of optometry and medicine meet, cooperation should exist. Improving our knowledge and skills in microbiology helps to facilitate such cooperation. Our experience has been most rewarding and interaction in this field with medical practitioners has been positive. The use of a high quality slitlamp is essential.
