Titel | Colour vision in eyes with IOL implants and normals |
Abstract Nr. | 3022 |
Doel | To determine colour vision (CV) in eyes with intraocular lens implants (IOLs) and compare these with normal age-matched controls. |
Methodes | In a set of 25 phakic eyes and 25 eyes with IOLs, CV testing, including the Farnsworth-Munsell 100 Hue test was performed 1 month after surgery. |
Resultaten | The total error score on the 100 Hue test in the study group was nearly identical to the results of the normals. Eyes with IOLs in patients under 70 years showed a lower error score than their phakic controls, whereas the opposite was observed in patients over 70 years. |
Conclusie | CV shows no major differences between eyes with IOLs and normal eyes, although the error score of younger patients with IOLs is better than the normals. Some patients observe a relative change in perception of some colours. The relative shift is small and is not picked up by standard clinical CV tests. The degradation of colour vision by cataracts is predominantly situated in the tritan-tetartan axis and increases with decreasing visual acuity. After IOL implantation this tritan defect is minimal and nearly similar to age-matched controls. |
