Primary Outcome Measures
NameTimeMethod
Percentage of spectacle independence (overall)1 month post-cataract surgery

This will be assessed by a Visual Quality Questionnaire, an 18 question multiple choice questionnaire to assess vision-related functioning. Grading scale: 0, no difficulty; 1, a little difficulty; 2, moderate difficulty; 3, quite difficult; 4, impossible to perform. Mean value(s) will be analyzed.

Percentage spectacle independence (overall)3 months post-cataract surgery

This will be assessed by a Visual Quality Questionnaire, an 18 question multiple choice questionnaire to assess vision-related functioning. Grading scale: 0, no difficulty; 1, a little difficulty; 2, moderate difficulty; 3, quite difficult; 4, impossible to perform. Mean value(s) will be analyzed.

Secondary Outcome Measures
NameTimeMethod
Spectacle independence subgroup analysis for subjects within 0.50 D spherical equivalent (SE)3 months post-cataract surgery

This will be assessed by a Visual Quality Questionnaire, an 18 question multiple choice questionnaire to assess vision-related functioning. Grading scale: 0, no difficulty; 1, a little difficulty; 2, moderate difficulty; 3, quite difficult; 4, impossible to perform. Mean value(s) will be analyzed.

Distribution of residual refractive error3 months post-cataract surgery

This will be measured by refractive error

Spectacle independence for distance, intermediate and near3 months post-cataract surgery

This will be assessed by a Visual Quality Questionnaire, an 18 question multiple choice questionnaire to assess vision-related functioning. Grading scale: 0, no difficulty; 1, a little difficulty; 2, moderate difficulty; 3, quite difficult; 4, impossible to perform. Mean value(s) will be analyzed.

Percentage of subjects with <=0.50 D of refractive cylinder3 months post-cataract surgery

This will be measured by refractive error

Subject satisfaction3 months post-cataract surgery

This will be assessed by a Visual Quality Questionnaire, an 18 question multiple choice questionnaire to assess vision-related functioning. Grading scale: 0, no difficulty; 1, a little difficulty; 2, moderate difficulty; 3, quite difficult; 4, impossible to perform. Mean value(s) will be analyzed.

Uncorrected binocular and monocular visual acuity at all distances3 months post-cataract surgery

This will be measured by visual acuity

Binocular, uncorrected distance visual acuity for patients within 0.50 D of intended target3 months post-cataract surgery

This will be measured by visual acuity

Contrast sensitivity (binocular)3 months post-cataract surgery

This will be measured by contrast sensitivity testing
