摘要目的:分析白内障手术患者术前视功能期望影响变量，并探讨其与疾病不确定感的相关性。方法:以便利抽样法从2023年1～12月在济南市第二人民医院接受治疗的白内障手术患者中选出511例作为研究样本，以一般资料调查问卷收集相关资料，以中国版视功能指数量表(Chinese Version of Visual Function Index-12，VF-12-CN量表)开展调查，并利用多重线性回归分析确定白内障手术患者术前视功能期望的关联因子，通过Pearson分析患者疾病不确定感和术前视功能期望的相关性。结果:调查结果表明，接受白内障手术的511例患者术前视功能期望水平评分均值(71.48±8.22)分；Pearson分析结果表明，患者术前视功能期望与疾病不确定感总分、各维度评分之间均存在正向相关关系，相关系数为0.434～0.754(均 P<0.05)；多重线性回归分析表明，年龄、术前教育、视功能影响程度、自我效能、既往手术经历均是影响白内障手术患者术前视功能期望的独立因子(均 P<0.05)。 结论:白内障手术患者术前视功能期望水平和年龄、术前教育、视功能影响程度、自我效能、既往手术经历紧密关联，且疾病不确定感水平和术前视功能期望亦呈明显的正向关系，因此，临床上要强化患者术前健康宣教、心理支持等措施，让患者树立积极的手术预期与信念。

abstractsObjective:To analyze the factors influencing preoperative expectations of visual function in cataract surgery patients and explore their correlation with disease uncertainty.Methods:A total of 511 cataract surgery patients treated in Jinan Second People's Hospital from January to December 2023 were selected as the research sample by convenience sampling.Relevant data were collected using a general information questionnaire. The Chinese Version of Visual Function Index-12 (VF-12-CN scale) was employed for the survey. Multiple linear regression analysis was used to identify the associated factors of preoperative visual function expectations in cataract surgery patients, and Pearson analysis was conducted to explore the correlation between patients' disease uncertainty and preoperative visual function expectations.Results:The investigation results indicated that the average preoperative visual function expectation level score of 511 patients who underwent cataract surgery was (71.48±8.22) points. The results of Pearson analysis showed that there were positive correlations between patients' preoperative visual function expectations and the total score of disease uncertainty as well as the scores of each dimension, with correlation coefficients ranging from 0.434 to 0.754( P<0.05). Multiple linear regression analysis indicated that age, preoperative education, the degree of impact on visual function, self-efficacy, and previous surgical experience were all independent factors affecting the preoperative visual function expectations of patients undergoing cataract surgery( P<0.05). Conclusions:The preoperative visual function expectation level of cataract surgery patients is closely related to age, preoperative education, the degree of visual function impact, self-efficacy, and previous surgical experience. Moreover, the level of disease uncertainty also shows a significant positive relationship with the preoperative visual function expectation. Therefore, in clinical practice, measures such as preoperative health education and psychological support for patients should be strengthened to help them establish positive surgical expectations and beliefs.
