Percentage of Eyes With Best Corrected Distance Visual Acuity (BCDVA) Equal to or Better Than 0.3 LogMAR - Monocular |
Visual acuity (VA) was assessed monocularly (eyes individually) with best refractive correction in place under photopic (well-lit) conditions at a distance of 5 meters using Chinese Standard Logarithmic VA charts. LogMAR typically ranges from -0.3 (20/10 vision on the Snellen chart) to 1 (20/200 vision). Lower scores indicate better vision. No hypothesis testing was pre-specified for this endpoint. |

Percentage of Eyes With Best Corrected Distance Visual Acuity (BCDVA) Equal to or Better Than 0.3 LogMAR - Binocular |
VA was assessed binocularly (eyes together) with best refractive correction in place under photopic conditions at a distance of 5 meters using Chinese Standard Logarithmic VA charts. LogMAR typically ranges from -0.3 (20/10 vision on the Snellen chart) to 1 (20/200 vision). Lower scores indicate better vision. No hypothesis testing was pre-specified for this endpoint. |

Mean Distance Corrected Intermediate Visual Acuity (DCIVA) - Monocular |
VA was assessed monocularly (eyes individually) with distance correction in place (plus or minus power) under photopic conditions at a distance of 60 centimeters using Chinese Standard Logarithmic VA charts. LogMAR typically ranges from -0.3 (20/10 vision on the Snellen chart) to 1 (20/200 vision). Lower scores indicate better vision. No hypothesis testing was pre-specified for this endpoint. |

Number of Participants Reporting a Severe Visual Disturbance (QUVID) |
The Questionnaire for Visual Disturbances (QUVID) is a patient-reported outcomes questionnaire that collects responses about 7 vision-related experiences. For each experience, the participant was asked, "In the Past 7 Days, How Severe Was Your Worst Experience" and responded on a 5-point scale, where 0-4 scale, where 0=none, 1=a little, 2=mild, 3=moderate, and 4=severe. No hypothesis testing was pre-specified for this endpoint. |

Number of Participants Reporting a Most Bothersome Visual Disturbance (QUVID) |
The Questionnaire for Visual Disturbances (QUVID) is a patient-reported outcomes questionnaire that collects responses about 7 vision-related experiences. For each experience, the participant was asked, "In the Past 7 Days, How Much Were You Bothered With" and responded on a 5-point scale, where 0=not bothered at all, 1=bothered a little, 2=bothered somewhat, 3=bothered quite a bit, and 4=bothered very much (most bothersome). No hypothesis testing was pre-specified for this endpoint. |
