AIM: To assess the patient-reported outcome of phacoemulsification with posterior chamber single focus foldable intraocular lens(SIOL)using the Chinese version of Catquest-8SF questionnaire. We would mainly evaluate the applicability of Catquest-8SF scale in northern Chinese and evaluate its sensitivity to cataract surgery.

METHODS:Prospective clinical case follow-up study. The patients were recruited from The Central Hospital of Tai'an and completed the Catquest-8SF questionnaire by face-to-face interviews before and 3mo after surgery at the hospital.

RESULTS: A total of 120 cataract patients completed the Catquest-8SF at baseline. The preoperative score of the Catquest-8SF-CN had a significant negative correlation with preoperative binocular mean weighted logMAR visual acuity and age(P<0.05), while a significant positive correlation with education level(P<0.001). The patients without systemic comorbidities got higher score than those who with(P<0.05). Three months after surgery, 102(85%)patients came for follow-up and completed the questionnaire. Significant improvement of visual acuity was observed in both binocular and monocular surgery groups(t=10.404, P<0.001). There was higher improvement in binocular weighted logMAR visual acuity of binocular surgery group than in monocular surgery group(P<0.001). The postoperative score were significantly higher in both groups than before(P<0.001). There was a significant improvement in the total score after cataract surgery. Ninety-four patients(92.2%)were very satisfied or satisfied with the operation. The degree of satisfaction was significantly correlated with the improvement score of the scale and it was also correlated with their expectation of the surgery.

CONCLUSION: The Chinese version of Catquest-8SF questionnaire is suitable for the age-related cataract population in northern China. It is highly responsive to cataract surgery and brief, so it may have the potential to become part of a routine clinical assessment for cataract surgery in China.
