研究目的: |
本研究评估干眼合并白内障患者滴用羟甲基纤维素钠、聚乙二醇、玻璃酸钠人工泪液后,相关眼部生物测量参数的即时变化。采用RCT设计,观察滴用后5/10/15分钟时各参数波动规律,分析制剂类型及作用时间对测量稳定性的影响,阐明人工泪液成分与角膜屈光状态、眼轴测量偏差的关联性,为白内障术前精准化生物测量策略建立提供依据。 |

Objectives of Study: |
This study evaluates the immediate changes in ocular biometric parameters following the instillation of carboxymethylcellulose sodium, polyethylene glycol, and sodium hyaluronate artificial tears in patients with dry eye and cataract. Utilizing a randomized controlled trial (RCT) design, we observe fluctuations in these parameters at 5, 10, and 15 minutes post-instillation. The study analyzes the effects of tear formulation type and duration of action on measurement stability, elucidates the relationship between artificial tear composition and corneal refractive status/axial length measurement deviations, and establishes evidence-based strategies for precise preoperative biometry in cataract surgery. |
