研究目的: |
探究有晶体眼人工晶状体(ICL)植入术不同调整距离(短距离、中长距离)对眼前节生物参数及术后视觉质量的影响。通过前瞻性观察性研究,分析术中调整 ICL 位置这一操作变量与术后眼前节生物参数及视觉质量的关系,明确调整距离对术后稳定性和视觉效果的潜在作用。 |

Objectives of Study: |
To investigate the effect of different adjustment distances (short distance, medium-to-long distance) during Implantable Collamer Lens (ICL) implantation on anterior segment biometric parameters and postoperative visual quality. Through a prospective observational study, this research aims to analyze the relationship between the operative variable of intraoperative ICL position adjustment and postoperative anterior segment biometric parameters and visual quality, thereby clarifying the potential impact of adjustment distance on postoperative stability and visual outcomes. |
