Contact lens care and complications

Abstract

In the past 20 years, great strides have been made in contact lens technology, but this progress has been accompanied by a multitude of lens-related problems. Bacterial keratitis may be the most significant problem, but reports of Acanthamoeba keratitis, a parasitic corneal infection, are increasing. Infectious complications may be lessened by proper lens care. Thermal disinfection is recommended for soft lenses with a low water content; chemical decontamination is preferred for soft contact lenses with a high water content.
