title: Interocular differences in higher-order aberrations on binocular visual performance.
abstract: OBJECTIVE
  To analyze the influence of higher-order aberrations on binocular visual performance under mesopic conditions.
  
  
  METHODS
  We measured aberrations in both eyes of 35 emmetropic observers with a Wasca aberrometer. Binocular visual performance was checked with both binocular summation for contrast sensitivity function and a parameter that characterizes stereopsis (maximum disparity).
  
  
  RESULTS
  Binocular summation and maximum disparity significantly decrease with increasing interocular differences in higher-order aberrations (total, coma, and spherical aberration).
  
  
  CONCLUSIONS
  At least some aspects of binocular visual performance are less effective for large interocular differences in higher-order eye aberrations.
