Dry eye syndrome triggered by wearing gas permable contact lens in keratoconus

A 48-year-old woman suffering from keratoconus of both eyes sought medical attention at the ophthalmology clinic with her left eye having been painful for prior 3 weeks, as well as increased sensitivity to light, foreign body sensation, stinging and watering eye. Her left eye was diagnosed with the dry eye syndrome, in addition to being treated with gas permable contact lens. Physical examination revealed corneal punctate epithelial erosions that stained positively with fluorescein in the left eye. The patient was ultimately diagnosed with dry eye disease of the left eye caused by gas permable contact lens usage.
