To investigate the relationship between preoperative expectations and actual postoperative outcomes of visual function (VF) among patients undergoing first eye cataract surgery.
A longitudinal study of 182 patients from hospitals in urban Southern China were surveyed prior to surgery and 3 month after cataract surgery regarding their preoperative, expected postoperative and actual postoperative VF for each of the items on the Catquest-9SF and their satisfaction with cataract surgery. In addition, detailed clinical data were collected preoperatively and postoperatively.
The majority of cataract patients in urban Southern China had high expectations for VF outcomes after cataract surgery and in most cases postoperative outcomes achieved the expected level of improvement. The mean (standard deviation, SD) preoperative Catquest-9SF score was 15.7 (5.86) and the mean (SD) expected postoperative score was 26.3 (2.93). The discrepancy between actual and expected improvement was significantly correlated with patients' health literacy, presence of systemic and ocular comorbidity, preoperative visual acuity of the surgery eye, LOCS III nuclear opalescence and cortical cataract grading.
Cataract patients in urban Southern China had high expectations for surgery outcomes. Patients with low level of health literacy and the presence of systemic and ocular comorbidity may need a comprehensive counseling to decrease the discrepancy regarding expected and actual outcomes.
探讨首次行白内障手术患者术前期望与术后视觉功能（VF）实际结果之间的关系。
对来自中国南方城市医院的182例患者进行纵向研究，在手术前及白内障手术后3个月，就Catquest-9SF各项内容询问其术前、术后预期及实际的VF情况，以及他们对白内障手术的满意度。此外，术前和术后收集详细的临床数据。
中国南方城市的大多数白内障患者对白内障手术后的VF结果期望较高，且在大多数情况下术后结果达到了预期的改善水平。术前Catquest-9SF评分的均值（标准差，SD）为15.7（5.86），术后预期评分的均值（SD）为26.3（2.93）。实际改善与预期改善之间的差异与患者的健康素养、全身及眼部合并症的存在、手术眼的术前视力、LOCS III核混浊度及皮质性白内障分级显著相关。
中国南方城市的白内障患者对手术结果期望较高。健康素养水平低以及存在全身和眼部合并症的患者可能需要全面的咨询，以减少预期与实际结果之间的差异。
