Clinical Investigation of the Visual Outcomes and Safety of AcrySof® IQ PanOptix® Toric Trifocal IOLs in an Asian Population

Percentage of Eyes With IOL Rotation Less Than 10 Degrees

时间窗: Month 3 postoperative, Month 6 postoperative

IOL rotation was defined as the difference in IOL axis of orientation from Day 1 postoperative. IOL rotation was assessed by the investigator using a slit lamp and was recorded in degrees, with a smaller number indicating less rotation. Eyes were assessed individually and combined for the analysis. No formal statistical hypothesis testing was prespecified for this outcome measure.

Mean Monocular Residual Manifest Cylinder for All Operative Eyes for All IOL Models Combined

时间窗: Month 3 postoperative, Month 6 postoperative

Manifest cylinder is the amount of added correction needed to compensate for any astigmatism that may be present. A manifest refraction (manual vision test) was conducted using letter charts and a phoropter. Residual manifest cylinder was measured in diopters and reported in plus cylinder form, with a smaller number indicating a lesser amount of added correction. Eyes were assessed individually and combined for the analysis. No formal statistical hypothesis testing was prespecified for this outcome measure.

Mean Binocular Best Corrected Distance Visual Acuity (BCDVA)

时间窗: Month 3 postoperative, Month 6 postoperative

Visual acuity (VA) was assessed at a distance of 4 meters with refractive correction in place using a visual acuity chart. VA was measured in logarithm of the minimum angle of resolution (logMAR), with 0.0 logMAR corresponding to 20/20 Snellen visual acuity, or normal distance eyesight. Eyes were assessed binocularly (eyes together). A lower value denotes better visual acuity. No formal statistical hypothesis testing was prespecified for this outcome measure.

Mean Binocular Distance Corrected Intermediate Visual Acuity (DCIVA)

时间窗: Month 3 postoperative, Month 6 postoperative

Visual acuity (VA) was assessed at a distance of 60 meters with distance correction (plus or minus power) in place. VA was measured in logarithm of the minimum angle of resolution (logMAR), with 0.0 logMAR corresponding to 20/20 Snellen visual acuity, or normal distance eyesight. Eyes were assessed binocularly (eyes together). A lower value denotes better visual acuity. No formal statistical hypothesis testing was prespecified for this outcome measure.

Mean Binocular Distance Corrected Near Visual Acuity (DCNVA)

时间窗: Month 3 postoperative, Month 6 postoperative

Visual acuity (VA) was assessed at a distance of 40 centimeters with distance correction (plus or minus power) in place using a visual acuity chart. VA was measured in logarithm of the minimum angle of resolution (logMAR), with 0.0 logMAR corresponding to 20/20 Snellen visual acuity, or normal distance eyesight. Eyes were assessed binocularly (eyes together). A lower value denotes better visual acuity. No formal statistical hypothesis testing was prespecified for this outcome measure.

Percentage of Eyes With Secondary Surgical Interventions (SSIs), by Category

时间窗: Up to Month 6 postoperative

A secondary surgical intervention (SSI) was defined as a surgical procedure occurring after primary implantation of the IOL. SSIs are reported categorically as SSIs related to the IOL and due to optical properties, SSIs related to the IOL and not due to optical properties, and SSIs unrelated to the IOL.

Percentage of Subjects With a Severe Visual Disturbance

时间窗: Preoperative, Month 3 postoperative, Month 6 postoperative

The Questionnaire for Visual Disturbances (QUVID) is a patient-reported outcomes questionnaire that collects responses from the subject about 7 vision-related experiences. For each experience, the subject was asked if he/she had experienced it during the past 7 days. Subjects responding "Yes" were then asked to rate how severe their worst experience was during the past 7 days. Subjects responded on a 5-point scale: 0=None; 1=A little; 2=Mild; 3=Moderate; 4=Severe. Subjects responding "No" were automatically imputed as reporting, "0=None." Percentage was calculated as number of subjects with response in specified category divided by number of subjects with data regardless of response, times 100. No formal statistical hypothesis testing was prespecified for this outcome measure.

Percentage of Subjects With a Most Bothersome Visual Disturbance (QUVID)

时间窗: Preoperative, Month 3 postoperative, Month 6 postoperative

QUVID is a patient-reported outcomes questionnaire that collects responses from the subject about 7 vision-related experiences. For each experience, the subject was asked if he/she had experienced it during the past 7 days. Subjects responding "Yes" were then asked to rate how severe their worst experience was with the vision-related experience in the past 7 days. Subjects responded on a 5-point scale: 0=Not bothered at all; 1=Bothered a little bit; 2=Bothered somewhat; 3=Bothered quite a bit; 4=Bothered very much. Subjects responding "No" were automatically imputed as reporting, "0=Not bothered at all. Percentage was calculated as number of subjects with response in specified category divided by number of subjects with data regardless of response, times 100. No formal statistical hypothesis testing was prespecified for this outcome measure.

Percentage of Subjects With Ocular Serious Adverse Events Including Serious Adverse Device Effects

时间窗: Up to Month 6 postoperative

An adverse event (AE) was defined as untoward medical occurrence, unintended disease or injury, or untoward clinical sign (including abnormal laboratory findings) in subjects, users, or other persons, whether or not related to the investigational medical device (test product). AEs were obtained through solicited and spontaneous comments from subjects and through observations by the Investigator. No formal statistical hypothesis testing was prespecified for this outcome measure.

Percentage of Subjects With Nonocular Serious Adverse Events Including Serious Adverse Device Effects

时间窗: Up to Month 6 postoperative

An adverse event (AE) was defined as untoward medical occurrence, unintended disease or injury, or untoward clinical sign (including abnormal laboratory findings) in subjects, users, or other persons, whether or not related to the investigational medical device (test product). AEs were obtained through solicited and spontaneous comments from subjects and through observations by the Investigator. No formal statistical hypothesis testing was prespecified for this outcome measure.
