Cohort study 

研究目的:

为白内障手术中IOL的选择提供高级别的临床证据。它不仅仅比较两种不同型号的IOL(SBL-2 和 SBL-3),更重要的是比较一种“差异化植入”策略与两种“标准化植入”策略的优劣。其最终目的是找到一种能最大程度满足患者远、中、近全程视力需求,并具有良好的立体视、对比敏感度和主观满意度的IOL植入方案,从而优化白内障手术后的视觉和生活质量。  

Objectives of Study:

To provide high-level clinical evidence for the selection of intraocular lenses (IOLs) in cataract surgery. This study not only compares two different models of IOLs (SBL-2 and SBL-3), but more importantly, evaluates the advantages and disadvantages of a differential implantation strategy versus two standardized implantation strategies. The ultimate goal is to identify an optimal IOL implantation protocol that maximizes patients’ full-range visual acuity (distance, intermediate, and near), while achieving good stereoscopic vision, contrast sensitivity, and subjective satisfaction, thereby optimizing visual function and quality of life after cataract surgery.
