The finite element method is now widely used in all areas of medicine and dentistry. We are pleased to see that Stitzel et al1 used the finite element method to analyze the effects of blunt trauma to the eye. Stitzel and colleagues found that lens stiffness is a critical parameter in the eye's response to blunt injury. However, the proper choice of baseline material properties is essential for the finite element method to reliably predict this or any other outcome.
