title: Remarks on WaveFront designed aberration correcting intraocular lenses.
abstract: OBJECTIVE
  Aberration correcting intraocular lenses (IOL), design philosophies and terminology are discussed. The study is restricted to wavefront errors and IOLs which exhibit rotational symmetry.
  
  
  METHODS
  Various combinations of corneas and wavefront designed IOLs are analyzed mathematically and numerically. A simple method for converting a plane wavefront into an ideal spherical wavefront is presented. Ocular wavefronts are calculated and Zernike polynomial coefficients of such wavefronts are determined. The study is restricted to wavefront errors which exhibit rotational symmetry.
  
  
  RESULTS
  Potential errors in fitting wavefront designed IOLs are identified and discussed.
  
  
  CONCLUSIONS
  The selection of wavefront designed IOLs should not solely be based on the corneal spherical aberration. Results may fall short of expectations, if corneal refractive power, corneal topography, pupil size, and anterior chamber depth are not taken into account.
