Figure 5

Rangeability of HOAs (baseline minus 2 weeks) for the treatment and control groups. A positive value of RMS rangeability indicates a decreasing of HOAs amplitude after treatment, and vice versa. For 3 mm zone, the 3rd and 5th HOAs decreased significantly after two weeks of artificial tears eye drops treatment. For 5 mm zone, the 3rd, 4th, 5th, and total HOAs all showed a significant decrease after 2 weeks of treatment.
