ESQ, Eye Symptom Questionnaire; MR, Medical Record; CI, Confidence Interval; freq, frequency

p <0.001 for all eight symptoms, McNemar’s test

^a“Present” reported as “somewhat/very much of a problem” in at least one eye and “Absent” reported as “no problem at all/a little bit of a problem” in both eyes for the symptom

^bMissing data was present for these symptoms, percentages based on: n=160 subjects for Blurry vision and Burning

^c“Present” reported as “moderate/severe/very severe” in at least one eye and “Absent” reported as “none/mild” in both eyes for the symptom

^dSymptoms were “Present” if documented in the medical record for the subject

^eSymptoms were “Absent” if documented as no symptom in the MR or not documented in the MR
