Abstract:
Contact lens(CL)is currently one of the most common methods of vision correction, with more than 140 million users worldwide and the demand is rising yearly as constantly development of materials and features. Wearing CL can lead to a variety of complications such as dry eye, corneal abrasions, giant papillary conjunctivitis, and infectious keratitis is one of the most severe complications. According to research, bacteria account for 80%～95% of the pathogens that cause CL-associated infective keratitis, it may have been related to the bacterial composition, virulence mechanism, biofilm formation and the combined effect of the lens itself and the process of use, which is prone to introducing pathogens, reducing antimicrobial capacity of the cornea and tears and causing ocular surface hypoxia and ocular surface inflammation. Overnight and prolonged lens wear, irregular lens purchase, use and care procedures can also be risk factors for bacterial infections. This article reviews the studies on the pathogenesis, risk factors, diagnosis, treatment and prevention of CL-related bacterial keratitis.
