A 24-year-old contact lens wearer with unilateral vision loss requiring penetrating keratoplasty

A 24-year-old myopic woman from rural Victoria who wore extended-wear soft contact lenses presented at Alfred Health, Melbourne, Australia, with a 2-week his‐ tory of left eye irritation, redness, photophobia, and reduced visual acuity. She denied sleeping while wear‐ ing lenses, trauma, or agricultural exposure. She had been treated with topical ciprofloxacin 0.3% drops with‐ out improvement. There was a history of travel to Viet‐ nam but only to coastal city centers. Initial symptoms developed in Australia prior to traveling to Vietnam, where they became progressively worse.
