Goldmann visual field testing was performed on ten patients while they were wearing the recently released DuraSoft 3 colored soft contact lenses. All patients but one had visual field constriction ranging from 5 degrees to 20 degrees. When the areas inside the three tested isopters were averaged, the amount of field loss ranged from 21% to 47%. Contact lens fitters as well as wearers should be warned of this potential complication.
