结局指标

主要结局

Vision Clarity During the Day - Distance Vision

时间窗: 3 weeks

Subjective expectation - Vision clarity during the day - distance vision was measured from three subjective expectation responses completed at the office. The responses were assigned numbers as below: Fell short of expectations = 1 Met my expectations = 2 Exceeded my expectations = 3
