• Intermittent touch of a pseudophakos to the corneal endothelium is heralded by three signs: ciliary flush, (local) corneal dystrophy, and cystoid macular edema. This syndrome is often missed, and should be ruled out whenever any one of these three signs is detected. Once diagnosed, elimination of the touch should be accomplished promptly. If discovered early, the syndrome may be reversed.
