利用最近获得的关于晶状体形状的新几何信息，开发了一个有限元模型，以估计典型 29 岁人眼在调节过程中作用在晶状体上的力。为了研究前部、后部和中央小带纤维插入区域的影响，建立了三个具有不同配置的模型。所有三种配置似乎都能够引起晶状体所需的调节变化。根据文献中的材料特性，三个模型中每个模型的估计总净力约为 0.08 N。(c) 2006 Elsevier Ltd。保留所有权利。
Using new geometric information on the shape of the lens that has recently become available, a finite element model has been developed in order to estimate the forces that act on the lens during accommodation for a typical 29-year-old human eye. To investigate the influence of the anterior, posterior and central zonular fibres insertion regions, three models with different configurations were built. All three configurations appeared to be capable of inducing the required accommodative changes in the lens. Based on material properties from the literature, the estimated summed net force for each of the three models was approximately 0.08 N. (c) 2006 Elsevier Ltd. All rights reserved.
