To determine the preoperative or postoperative patient-related factors that make patients benefit more or less from cataract surgery.
Multicenter, prospective, cross-sectional Swedish National Cataract Register study.
A total of 14 817 patients who underwent cataract surgery from 2000 to 2006 in 42 Swedish ophthalmology departments.
The patients completed the Catquest questionnaire before and 6 months postoperatively. The 9 questions in the revised Catquest-9SF were selected from the Catquest and recoded by Rasch analysis, which makes it possible to use parametric statistics when analyzing the study data. The change from preoperative to postoperative, the postoperative mean subjective visual function, and satisfaction with vision were assessed with multiple regression or logistic regression with dummy variables where appropriate, in relation to waiting time, age, preoperative and postoperative corrected distance visual acuity (CDVA), ocular comorbidity, a first- or second-eye surgery, gender, achieved postoperative refraction, correct sign biometry prediction error, and absolute biometry prediction error.
Three outcome measures from Catquest-9SF of patient self-assessed visual function after cataract surgery.
Young age (P<0.001), low preoperative CDVA (P<0.001), high postoperative CDVA (P<0.001), no ocular comorbidity (P<0.001), and postoperative myopia (-2 to 0 diopters [D]) instead of hyperopia (>0 to +2 D; P<0.05) led to significantly greater improvement in subjective visual function and a better postoperative subjective visual function than the counterparts. Women (P<0.001) and patients who underwent a first-eye surgery (P<0.001) had greater improvement but lower postoperative subjective visual function (P<0.001) than men and patients who underwent a second-eye surgery. A correct sign biometry prediction error of plus instead of minus led to greater improvement in subjective visual function (P<0.01) but no difference in postoperative subjective visual function. The absolute biometry prediction error had no effect on the change in subjective visual function, the subjective mean visual function or satisfaction with vision.
Several patient preoperative and postoperative factors are related to the self-assessed benefit of cataract surgery. Age, preoperative and postoperative CDVAs, ocular comorbidity, a first- or second-eye surgery, gender, and achieved postoperative refraction were related to changes in subjective visual function, subjective visual function, and satisfaction with vision.
确定使患者从白内障手术中获益更多或更少的术前或术后患者相关因素。
多中心、前瞻性、瑞典全国白内障登记处的横断面研究。
共有 14817 名患者在 2000 年至 2006 年间在 42 家瑞典眼科诊所接受了白内障手术。
患者在术前和术后 6 个月时完成 Catquest 问卷。修订后的 Catquest-9SF 中的 9 个问题来自 Catquest，并通过 Rasch 分析重新编码，这使得在分析研究数据时可以使用参数统计。使用多元回归或逻辑回归（适当情况下使用虚拟变量），根据等待时间、年龄、术前和术后矫正远视力（CDVA）、眼部合并症、第一或第二只眼手术、性别、术后视力、正确的符号生物测量预测误差和绝对生物测量预测误差，评估从术前到术后的变化、术后平均主观视觉功能和对视觉的满意度。
白内障手术后患者自我评估视觉功能的 Catquest-9SF 三个结果测量。
年轻的年龄（P<0.001）、低术前 CDVA（P<0.001）、高术后 CDVA（P<0.001）、无眼部合并症（P<0.001）和术后近视（-2 至 0 屈光度[D]）而不是远视（>0 至+2 D；P<0.05）导致主观视觉功能显著改善，术后主观视觉功能更好。女性（P<0.001）和接受第一只眼手术的患者（P<0.001）比男性和接受第二只眼手术的患者有更大的改善，但术后主观视觉功能较低（P<0.001）。正确的符号生物测量预测误差为正而不是负导致主观视觉功能显著改善（P<0.01），但对术后主观视觉功能无影响。绝对生物测量预测误差对主观视觉功能变化、主观平均视觉功能或对视觉的满意度没有影响。
一些患者术前和术后的因素与白内障手术的自我评估获益相关。年龄、术前和术后 CDVA、眼部合并症、第一或第二只眼手术、性别和术后视力与主观视觉功能变化、主观视觉功能和对视觉的满意度相关。
