Wavefront aberrations, depth of focus, and contrast sensitivity with aspheric and spherical intraocular lenses: Fellow-eye study

Aspheric IOLs significantly reduced spherical aberration, improving mesopic contrast sensitivity. Vertical coma was reduced with aspheric IOLs. Reduction of aberrations may be responsible for reduced depth of focus with aspheric IOLs. This may be disadvantageous for near vision and reading ability.
