    ### Response:
    Complete LCAT deficiency is a disorder that primarily affects the eyes and kidneys.  In complete LCAT deficiency, the clear front surface of the eyes (the corneas) gradually becomes cloudy. The cloudiness, which generally first appears in early childhood, consists of small grayish dots of cholesterol (opacities) distributed across the corneas.
