Percentage of Participants Gaining 3 Lines or More in Mesopic, High-contrast, Binocular DCNVA, Without Losing More Than 5 Letters of Mesopic, High-Contrast, Binocular CDVA With the Same Refractive Correction at Day 30, Hour 3 |
Visual acuity for near (40 centimeter (cm)) and distance (4 meter (m)) targets were measured in mesopic conditions using an eye chart. High contrast corrected distance visual acuity (CDVA) was assessed binocularly (in each eye) using the provided visual acuity charts for distance vision in a room with mesopic lighting conditions measured at the target. Forced choice letter by-letter scoring was used for each test and the total number of correct letters or the highest value (number) of the grid identified (as applicable) were recorded. Mesopic condition was defined as low lighting 3.2 to 3.5 candelas per square meter (cd/m^2) measured at the target. DCNVA= distance-corrected near visual acuity. |

Mean Change From Baseline in Mesopic Near Vision Presbyopia Task-based Questionnaire (NVPTQ) Performance Score at Day 30, Hour 3 |
NVPTQ had 12 questions on 4 reading tasks(reading a paragraph from book, excerpts from a newspaper article, portion of a nutrition label, and a section from restaurant menu). Participants completed specific reading tasks under mesopic conditions without any near-vision correction and answered 3 questions for each task, rated as 0=I could not read any text due to problems seeing up close,1=poor,2=fair,3=good,4=very good,5=excellent; impact of squinting as 0=No,I did not squint, 1=Yes, squinting helped me read some/all text, 2=Yes,but I still could not read any of the text; and satisfaction as 0=very dissatisfied to 4=very satisfied. The score based on vision-related ability and impact of squinting=(Book testlet+Newspaper testlet+Menu testlet+Nutrition Label testlet)/(testlets with non-missing responses), total possible score of 0-5. Higher scores=better outcomes;positive change from Baseline=improved performance (reading ability). |

Mean Change From Baseline in Mesopic NVPTQ Satisfaction Score at Day 30, Hour 3 |
NVPTQ had 12 questions on 4 reading tasks(reading a paragraph from book, excerpts from a newspaper article, portion of a nutrition label, and a section from restaurant menu). Participants completed specific reading tasks under mesopic conditions without any near-vision correction and answered 3 questions for each task, related as 0=I could not read any text due to problems seeing up close,1=poor,2=fair,3=good,4=very good,5=excellent; impact of squinting as 0=No, I did not squint, 1=Yes, squinting helped me read some/all text, 2=Yes, but I still could not read any of the text; and satisfaction as 0=very dissatisfied to 4=very satisfied. NVPTQ Satisfaction Score=(Book testlet+Newspaper testlet+Menu testlet+Nutrition Label testlet)/(testlets with non-missing responses)based on satisfaction items for a total possible score of 0 to 4. Higher scores=better outcomes; a positive change from Baseline indicates higher satisfaction. |

Each item had response categories:0=never to 4=all the time. Items 3, 4, 5, and 6 had additional response categories with values of 9/10 to indicate the question is not applicable to participant and were assigned missing values.PICQ Coping Score:(Item 1,2 Testlet+Item 3,4 Testlet+Item 5+Item 6+Item 12+Item 13)/non-missing responses to the 6 components of coping score where Items 1,2 Testlet=(Item1+Item2)/non-missing responses to Items 1,2;Items 3,4 Testlet=(Item3+Item4)/non-missing responses to Items 3, 4.

PICQ had 20 questions about impact experienced by participants due to their problems seeing up over past 7 days. Impact domain of PICQ has 6 items:Item9:Rely on others,Item15:rest eyes,Item16:Feel older,Item17:Feel self-conscious,Item19:Take longer to complete task,Item20:Inconvenient.First 5 impacts items include response ranges from 0=never to 4=all of time. Item20 ranged from 0=Not at all,to 4=Extremely. Item9 included an additional response category, labeled with value of 9 to indicate question is not applicable because participant did not have opportunity to experience impact responses are assigned missing values. PICQ Impacts Score=[(Items 9+15+16&17 Testlet+Item19+Item20)/(nonmissing responses to 5 components of impacts score)] where Items 16&17 Testlet=(Items16+17)/non-missing responses to Items16 and 17. PICQ Impact score ranged 0-4, 0=least amount of impacts,4=greatest amount of impacts. Higher scores correspond to poorer outcomes; negative change from Baseline=improvement. |
