Modelling oblique astigmatism in eyes with known peripheral refraction and optical dimensions.
The optical dimensions of 34 young adult eyes were measured by optical and A-scan ultrasound methods. Peripheral refraction was recorded up to field angles of 40 degrees to produce results for oblique astigmatism. These findings were modelled in schematic eyes with a monoindicial crystalline lens but with varying levels of asphericity of the optimal surfaces.
