Colour discrimination in pseudophakia.

A study was undertaken to examine the colour discrimination of fifty pseudophakic patients and to compare results with fifty age matched normal observers. Using the Farnsworth-Munsell 100-Hue test and Desaturated panel D15, performance does not differ significantly from the age matched normals, although a theoretically superior colour discriminative ability might be expected in pseudophakia. A slight trend for increasing error scores with advancing age in pseudophakia lends some support to the importance of neural factors in the ageing of colour discrimination. Several other factors influencing colour vision in pseudophakia are discussed.
