Abstract

Abstract In this paper, we present a cornea deformation model based on the idea of extending the ‘neutral axis’ model to two-dimensional deformations. Considering this simple model, assuming the corneal tissue to behave like a continuous, isotropic and non-compressible material, we are able to partially describe, e.g., the observed deviation in refractive power after lenticule extraction treatments. The model provides many input parameters of the patient and the treatment itself, leading to an individual compensation ansatz for different setups. The model is analyzed for a reasonable range of various parameters. A semi-quantitative comparison to real patient data is performed.

一个简单的角膜变形模型

摘要本文提出了一种基于“中性轴”模型扩展到二维变形的角膜变形模型。考虑到这个简单的模型，假设角膜组织表现得像一个连续的、各向同性的、不可压缩的材料，我们能够部分地描述，例如，在晶状体提取处理后观察到的屈光功率偏差。该模型提供了患者和治疗本身的许多输入参数，导致不同设置的个体补偿分析。对模型进行了分析，以确定各参数的合理取值范围。与真实患者数据进行半定量比较。
