Outcome Measures

Primary Outcome Measures :
  1. Percentage of spectacle independence (overall) [ Time Frame: 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.

  2. Percentage spectacle independence (overall) [ Time Frame: 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 :
  1. Spectacle independence for distance, intermediate and near [ Time Frame: 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.

  2. Spectacle independence for distance, intermediate and near [ Time Frame: 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.

  3. Spectacle independence subgroup analysis for subjects within 0.50 D spherical equivalent (SE) [ Time Frame: 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.

  4. Spectacle independence subgroup analysis for subjects within 0.50 D spherical equivalent (SE) [ Time Frame: 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.

  5. Binocular, uncorrected distance visual acuity for patients within 0.50 D of intended target [ Time Frame: 3 months post-cataract surgery ]
    This will be measured by visual acuity

  6. Subject satisfaction [ Time Frame: 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.

  7. Uncorrected binocular and monocular visual acuity at all distances [ Time Frame: 3 months post-cataract surgery ]
    This will be measured by visual acuity

  8. Distribution of residual refractive error [ Time Frame: 3 months post-cataract surgery ]
    This will be measured by refractive error

  9. Contrast sensitivity (binocular) [ Time Frame: 1 month post-cataract surgery ]
    This will be measured by contrast sensitivity testing

  10. Contrast sensitivity (binocular) [ Time Frame: 3 months post-cataract surgery ]
    This will be measured by contrast sensitivity testing

  11. Percentage of subjects with <=0.50 D of refractive cylinder [ Time Frame: 1 month post-cataract surgery ]
    This will be measured by refractive error

  12. Percentage of subjects with <=0.50 D of refractive cylinder [ Time Frame: 3 months post-cataract surgery ]
    This will be measured by refractive error
