研究目的:

主要目的:比较不同光学设计(单焦点、连续视程型、双焦点、三焦点及单焦增强型)IOL在术后关键屈光点(0D、-1.5D、-3.0D等)的视力、离焦曲线、波前像差、对比敏感度和患者主观Catquest-9SF问卷评估等方面的差异(本研究重点根据临床实际及参考既往文献,选取具有潜在临床价值,以及IOL型号间上述结局指标的差异)。 次要目的:评估不同功能性IOL对倾斜与偏心的包容性,分析IOL倾斜/偏心对波前像差、离焦曲线、对比敏感度患者主观Catquest-9SF问卷评估等方面的影响。 探索性目的:探索术前通过IOLMaster 700和iTrace等设备测量的眼部参数,对不同光学设计IOL植入术后视觉质量的影响  

Objectives of Study:

Main objective: To compare the differences in visual acuity, defocus curves, wavefront aberrations, contrast sensitivity, and patient subjective Catquest-9SF questionnaire evaluations at key refractive points (0D, -1.5D, -3.0D, etc.) after surgery among different optical designs (monofocal, continuous range type, bifocal, trifocal, and monofocal enhanced) of intraocular lenses (IOLs) (This study focuses on selecting outcomes with potential clinical value and differences in these outcomes among IOL models based on clinical reality and reference to previous literature). Secondary objective: To evaluate the inclusiveness of different functional IOLs for tilt and eccentricity, and to analyze the effects of IOL tilt/eccentricity on wavefront aberrations, defocus curves, contrast sensitivity, and patient subjective Catquest-9SF questionnaire evaluations. Exploratory objective: To explore the impact of preoperative ocular parameters measured by devices such as IOLMaster 700 and iTrace on the visual quality after IOL implantation of different optical designs.
