| Title | Contrast Sensitivity & Colour Vision in Pseudophakic & Normal Eyes: A Thorough Comparison |
| Purpose | To determine contrast sensitivity (CST) and colour vision (CV) in eyes with either aspheric or spheric intra-ocular lens implants (IOLs) and compare those with normal age-matched controls. |
| Methods | Eyes with either spheric (11) or aspheric (34) IOLs and normal eyes (34) were tested for CST for 5 spatial frequencies using a Vistech C configuration at different background illumination levels with best correction. In addition, in a set of normals and eyes with aspheric IOLs, CV testing was performed, including the Farnsworth-Munsell 100 Hue test. All BCVAs were within the normal range both for eyes with IOLs and normal controls. |
| Results | CST levels were generally higher in eyes with aspheric IOLs than in those with spheric IOLs. This difference was more pronounced in mesopic than in photopic environments. CST in eyes with aspheric IOLs was only mildly inferior to that in normal controls in mesopic conditions, whereas no difference was observed in photopic environments. CV in eyes with aspheric IOLs was virtually identical than in normal eyes. |
| Conclusion | CST is better in eyes with aspheric IOLs than in those with spheric IOLs. This effect is more pronounced at low light levels. CST is only slightly better in normal than in eyes with aspheric IOLs in mesopic environments, whereas no difference is observed in photopic conditions. CV shows no major differences between eyes with aspheric IOLs and normals. |
