Postoperative patient satisfaction score and dysphotopsia grading.

Patient satisfaction score (mean ± SD)
Distance vision	97.97 ± 2.13
Intermediate vision	99.36 ± 0.64
Near vision	96.84 ± 2.36
Postoperative spectacle independence [% of patients] (n = 30)
Distance vision	93.33% (28)
Intermediate vision	100% (30)
Near vision	86.67% (26)
Postoperative dysphotopsia grading [% of patients] (n = 30)
Grade 0 (nil)	93.33% (28)
Grade 1 (mild)	6.66% (2)
Grade 2 (moderate)	0% (0)
Grade 3 (severe)	0% (0)

Satisfaction questionnaire included scores ranging from 0 to 100, where 0 indicated not at all satisfied and 100 indicated completely satisfied, without the need of spectacles. Postoperative spectacle independence was evaluated as the percentage of patients who were completely free or did not feel the need of glasses for a particular distance. Dysphotopsia grading was done as per the following questionnaire: 0 = nil, no dysphotopsia symptoms experienced; 1 = mild, minimal dysphotopsia not affecting night vision and routine activities; 2 = moderate, dysphotopsia symptoms affecting night vision and routine activities, but manageable; 3 = severe, bothersome dysphotopsia, severe enough to interfere in routine activities.
