title: Comparison of color perception after tinted blue light-filtering and clear ultraviolet-filtering intraocular lens implantation.
abstract: OBJECTIVE
  To compare color perception after implantation of clear and yellow-tinted intraocular lenses (IOLs).

  METHODS
  Comparative case series.
  
  
  METHODS
  This study evaluated eyes that had implantation of an Acrysof IQ SN60WF yellow-tinted IOL or an Acrysof SA60AT clear IOL. All eyes were evaluated postoperatively at 1 month and 3 months. The uncorrected distance visual acuity, intraocular pressure, and color vision (Ishihara pseudoisochromatic test, Edridge-Green lantern test, Heidelberg anomaloscope, and Farnsworth-Munsell (FM) 100-hue test) were evaluated.
  
  
  RESULTS
  Both IOL groups comprised 50 eyes. There were no significant differences between the 2 groups in color vision on any of the 4 tests (P≥.05). Plotting the error scores on the polarity graph of the FM 100-hue test showed that eyes with a yellow-tinted IOL did not have a specific axis of confusion.
  
  
  CONCLUSIONS
  There was no difference in color perception between the 2 IOLs irrespective of the color vision test used.
