Aims To evaluate visual acuity (VA) outcomes of cataract surgery, and factors associated with good visual outcomes, among a population with diabetes. Methods Participants with type 2 diabetes enrolled in The Action to Control Cardiovascular Risk in Diabetes (ACCORD) study and ACCORD-eye substudy. 1136 eyes of 784 ACCORD participants receiving cataract surgery during follow-up (2001–2014) were included. Of these, 362 eyes had fundus photographs gradable for diabetic retinopathy. The main outcome measure was the achievement of postoperative VA of 20/40 or better. Results In the sample of 1136 eyes, 762 eyes (67.1%) achieved good visual outcome of 20/40 or better. Factors predictive of good visual outcome were higher level of educational attainment (college vs some high school, OR 2.35 (95% CI 1.44 to 3.82)), bilateral cataract surgery (OR 1.55 (1.14 to 2.10)) and preoperative VA (20/20 or better vs worse than 20/200, OR 10.59 (4.07 to 27.54)). Factors not significantly associated (p>0.05) included age, sex, race, smoking, diabetes duration, blood pressure, lipid levels and haemoglobin A1C (HbA1C). In the subsample of 362 eyes, absence of diabetic retinopathy was associated with good visual outcome (OR 1.73 (1.02 to 2.94)). Conclusion Among individuals with diabetes, two-thirds of eyes achieved good visual outcome after cataract surgery. Notable factors associated with visual outcome included preoperative VA and diabetic retinopathy, but not HbA1C, underscoring that while certain ocular measures may help evaluate visual potential, systemic parameters may not be as valuable. Sociodemographic factors might also be important considerations. Although the current visual prognosis after cataract surgery is usually favourable, certain factors still limit the visual potential in those with diabetes. Data may be obtained from a third party and are not publicly available. Action to Control Cardiovascular Risk in Diabetes (ACCORD)

2 型糖尿病白内障手术后的视力结果：控制糖尿病心血管风险行动 (ACCORD) 研究


目的 评估糖尿病人群白内障手术的视力 (VA) 结果以及与良好视力结果相关的因素。方法 患有 2 型糖尿病的参与者参加了控制糖尿病心血管风险行动 (ACCORD) 研究和 ACCORD-眼睛亚研究。随访期间（2001-2014 年）接受白内障手术的 784 名 ACCORD 参与者的 1136 只眼睛被纳入其中。其中，362 只眼睛的眼底照片可分级为糖尿病视网膜病变。主要结果指标是术后视力达到 20/40 或更好。结果 在 1136 只眼样本中，762 只眼（67.1%）获得了 20/40 或更好的良好视力结果。预测良好视力结果的因素包括较高的教育程度（大学与部分高中相比，OR 2.35（95% CI 1.44 至 3.82））、双侧白内障手术（OR 1.55（1.14 至 2.10））和术前 VA（20/20）或优于 20/200，或 10.59（4.07 至 27.54））。不显着相关的因素 (p>0.05) 包括年龄、性别、种族、吸烟、糖尿病病程、血压、血脂水平和糖化血红蛋白 (HbA1C)。在 362 只眼睛的子样本中，不存在糖尿病视网膜病变与良好的视力结果相关（OR 1.73（1.02 至 2.94））。结论 在糖尿病患者中，三分之二的眼睛在白内障手术后获得了良好的视力结果。与视力结果相关的显着因素包括术前 VA 和糖尿病视网膜病变，但不包括 HbA1C，这强调虽然某些眼部测量可能有助于评估视力潜力，但全身参数可能没有那么有价值。社会人口因素也可能是重要的考虑因素。 尽管目前白内障手术后的视力预后通常良好，但某些因素仍然限制了糖尿病患者的视力潜力。数据可能从第三方获得，并且不公开。控制糖尿病心血管风险的行动（ACCORD）
