Methods One hunderd amd ten human subjects (one hunderd and seventy-four eyes) were included in this research. Retinoscopy was made to measure refractive errors, corneal topographer was measured by corneal topography system, Tonometry was used to measure IOP, Ultrasonagraphy was applied to measure anterior chamber length, len thickness and vitreous length respectively, Laser interference biometer was used to measure axial length, Optical coherence tomography was used to measure retina thickness of fovea area. Based on spherical equivalent subjects were divided into four groups: emmetropia group (SE0.50D), low-myopia group (-0.50D≤SE3.00D), moderate myopia group (-3.00D≤SE6.00D) and high myopia group (SE≥-6.00D).

A deformable model is used to reconstruct the shape of the LV: first, the dynamic equation governing the surface deformation is deduced; secondly the image planes are mapped to the reconstruction coordinate system. From the slices data, the external force exerted on the surface is defined and the elastic force of the surface is constructed by mean curvature of the deformation surface. Finally, a level set method is applied to solve the dynamic equation for LV shape.
