We examined the adherence of a human corneal isolate of Pseudomonas
aeruginosa to unused rigid gas-permeable and hydrogel contact lenses.
Adherence to rigid gas-permeable lenses was greater than the adherence to
hydrogels. The lower incidence of microbial keratitis associated with rigid
gas-permeable lenses, as compared with hydrogel lenses, may be attributed
to the more rigorous cleaning and disinfection possible for rigid
gas-permeable lenses and/or patient noncompliance with complicated
disinfection systems used with hydrogel lenses.
