Removing cataracts on a hospital ship in Guatemala

USNS Comfort is a military hospital ship deployed to Latin America on a five-month humanitarian mission.

Just like any hospital, it has operating theatres and wards for general and special surgical care.

Staff perform 300 cataract operations during this mission, many of them mature cataracts, which depend less on advanced technology than on the surgeon's skill.
