This tool lets you study how variations in corneal asphericity (Q factor) influence spherical aberration (Z4,0), the vergence distribution and the depth of field. Through interactive 3D visualisations and real-time computations, it connects theoretical optics to clinical practice by showing the link between corneal shape and visual quality. It is particularly useful for presbyopia-correction procedures and for choosing an aspheric IOL.
Key features
- Interactive manipulation of the Q factor with real-time spherical-aberration analysis
- Vergence mapping (radial and Laplacian) to assess the induced multifocality
- Through-focus MTF analysis and depth-of-field optimisation
- PSF visualisation and convolved-letter simulation
- Conversion between the corneal plane and the spectacle plane
- Inclusion of the eye’s native spherical aberration in the model
