研究目的:

本项目拟通过纳米压痕测量方法,探讨角膜基质透镜的弹性模量、渗透性等,研究不同近视程度患者的生物力学变化,为角膜生物力学探测的临床应用奠定重要的科学基础。为评估高度近视患者的角膜生物力学特性提供了参考,同时对近视风险预测、个性化屈光手术安全规划具有重要的指导意义。  

Objectives of Study:

This project intends to use the nanoindentation measurement method to investigate the elastic modulus, permeability, etc., of corneal stromal lenses, and study the biomechanical changes in patients with different degrees of myopia, so as to lay an important scientific foundation for the clinical application of corneal biomechanical detection. It provides a reference for evaluating the corneal biomechanical characteristics of patients with high myopia, and also has important guiding significance for myopia risk prediction and the safety planning of personalized refractive surgery.
