Percentage of spectacle independence (overall)
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.
Time frame: 1 month post-cataract surgery
