—Microbial keratitis, especially that caused by gram-negative bacilli such as Pseudomonas aeruginosa, is known to be the most serious complication of the use of daily-wear, extended-wear, and therapeutic soft contact lenses. Factors that have been implicated in the pathogenesis of contact lens-associated microbial corneal ulceration include poor hygiene, poor compliance with instructions for proper lens care and sterilization, the use of contaminated lens care solutions, the development of contact lens deposits and coatings that facilitate the adherence of microorganisms to the contact lenses, and epithelial trauma, caused by either the removal or insertion of the lenses or by abnormalities of the lenses themselves.1Recently, disposable extended-wear contact lenses were introduced for the correction of myopia (Accuvue, Johnson & Johnson, New Brunswick, NJ). It has been speculated that, because these lenses are packaged in sterile solutions, do not require the use of lens care solutions that can
