What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Monocular Photopic Distance Corrected Intermediate Visual Acuity (DCIVA) at 66 Centimeters (cm)
Time Frame: Month 3 (70-100 days post second eye implantation)
Visual Acuity (VA) was assessed monocularly (each eye separately) under photopic (well-lit) conditions using best distance correction (distance refraction) and high contrast, Early Treatment Diabetic Retinopathy Study (ETDRS) chart at 66 cm from spectacle plane. It was measured in logarithm of the minimum angle of resolution (logMAR), with 0.02 logMAR increment corresponding to a single letter or 0.1 logMAR increment corresponding to 5 letters, or 1 line, on an ETDRS chart. A lower numeric value represented better VA. This analysis was prespecified for the first operative eye.
Month 3 (70-100 days post second eye implantation)
Percentage of Subjects With Ocular Adverse Events
Time Frame: Day 0 (first operative eye visit) up to Month 6 (120-180 days post second eye implantation)
An adverse event (AE) was defined as any untoward medical occurrence, unintended disease or injury, or untoward clinical signs (including abnormal laboratory findings) in subjects, users or other persons, whether or not related to the investigational medical device (test article). Ocular AEs are events localized to the eye. Cumulative and persistent serious adverse events as defined by ISO 11979-7:2014 were collected for Model DFT015 first and second eyes. No formal statistical hypothesis testing was planned.
Day 0 (first operative eye visit) up to Month 6 (120-180 days post second eye implantation)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Monocular Photopic Best Corrected Distance Visual Acuity (BCDVA) at 4 Meters (m)
Time Frame: Month 3 (70-100 days post second eye implantation)
VA was tested monocularly under photopic conditions using the correction obtained from the manual manifest refraction and 100% contrast, ETDRS charts at a distance of 4 m from the spectacle plane. VA was measured in logMAR, with 0.02 logMAR increment corresponding to a single letter or 0.1 logMAR increment corresponding to 5 letters, or 1 line, on an ETDRS chart. A lower numeric value represented better VA. This analysis was prespecified for the first operative eye.
Month 3 (70-100 days post second eye implantation)
Monocular Photopic Distance Corrected Near Visual Acuity (DCNVA) at 40 cm
Time Frame: Month 3 (70-100 days post second eye implantation)
VA was tested monocularly under photopic conditions using best distance correction (distance refraction) and high contrast, ETDRS chart set at 40 cm from the spectacle plane using the near point rod. VA was measured in logMAR, with 0.02 logMAR increment corresponding to a single letter or 0.1 logMAR increment corresponding to 5 letters, or 1 line, on an ETDRS chart. A lower numeric value represented better VA. This analysis was prespecified for the first operative eye.
Month 3 (70-100 days post second eye implantation)
Monocular Photopic Distance Corrected Depth of Focus Assessed by the Mean Defocus Curve
Time Frame: Month 3 (70-100 days post second eye implantation)
Depth of focus was assessed at 4 meters under photopic (well-lit) conditions using best corrected distance refraction, added defocus and 100% contrast ETDRS charts. VA was measured between +1.50 Diopter (D) and -2.50 D in 0.5 D defocus steps, except in the region from +0.50 D through -0.50 D, which was assessed in 0.25 D steps. VA was measured in logMAR, with 0.02 logMAR increment corresponding to a single letter or 0.1 logMAR increment corresponding to 5 letters, or 1 line, on an ETDRS chart. The depth of focus was estimated as the dioptric range between zero defocus and the first point on the negative lens induced mean defocus curve that crosses the 0.2 logMAR using a linear interpolation. A lower numeric value represents better VA. This analysis was pre-specified for the first operative eye. No formal statistical hypothesis testing was planned.
Month 3 (70-100 days post second eye implantation)
Monocular Mesopic Contrast Sensitivity at 12 Cycles Per Degree (Cpd)
Time Frame: Month 6 (120-180 days post second eye implantation)
Contrast sensitivity (i.e., the ability to detect objects by distinguishing them from their background) was assessed monocularly with the subject's best spectacle correction under mesopic (low, but not quite dark) conditions at a distance of 8 feet (2.45 m) from the eye at a spatial frequency of 12 cpd using the Vector Vision CSV 1000-HGT with and without a glare source. Raw scores from contrast sensitivity testing were transformed to log units. A higher numeric value represented better contrast sensitivity. This analysis was prespecified for the first operative eye.
Month 6 (120-180 days post second eye implantation)
Percentage of Subjects Who Respond "Never" to Question 1 of the Spectacle Use Questionnaire: "How Often Do You Wear Eyeglasses for Any Purpose?"
Time Frame: Month 6 (120-180 days post second eye implantation)
Proportion of subjects was reported as a percentage. No formal statistical hypothesis testing was planned.
Month 6 (120-180 days post second eye implantation)
Percentage of Subjects Who Respond "Never" to Question 3 of the Spectacle Use Questionnaire: "How Often Do You Wear Eyeglasses for Intermediate Tasks (e.g., Computer)?"
Time Frame: Month 6 (120-180 days post second eye implantation)
No formal statistical hypothesis testing was planned.
Month 6 (120-180 days post second eye implantation)
