title: [Supernormal sight and high-resolution retinal imaging: a review].
abstract: BACKGROUND
  An analysis of the wavefront in human eyes has yielded new findings with respect to the cones and other elements of the retina. But the correction of higher-order wavefront aberrations in photorefractive processes is still associated with basic difficulties.
  
  
  METHODS
  The world literature relating to wavefront corrections in experimental research and the correction of photorefractive aberrations in the human eye is surveyed.
  
  
  CONCLUSIONS
  The correction of higher-order aberrations has permitted a vast improvement in the resolution of the cone-pattern picture existing in vivo. As a consequence, new findings with regard to colour physiology have been forthcoming. On the other hand, the application of wavefront corrections in photorefractive procedures has been only partially successful.
