Colour vision and retinal nerve fibre layer photography in patients with an Acrysof Natural intraocular lens
Vuori ML; Mantyjarvi MActa Ophthalmologica Scandinavica 2006; 84: 92-94
PURPOSE: To study colour vision and retinal nerve fibre layer (RNFL) photographs in patients with an Acrysof Natural intraocular lens (IOL). METHODS: We carried out a randomized double-blind study. An Acrysof Natural IOL (model SN60AT) was implanted in 25 eyes of 19 patients and an Acrysof IOL (model SA60AT) was implanted in 27 eyes of 18 control patients. The patients returned for colour vision tests and fundus photography 1-6 months after the surgery. RESULTS: Standard pseudoisochromatic plates, part 2, were correctly interpreted and the Farnsworth-Munsell 100-hue test (FM 100) total and individual box scores were normal in all IOL eyes. In the FM 100 hue test there were no significant differences in the results of the total error scores or the error scores of the individual boxes between the eyes with Acrysof Natural and those with Acrysof lenses. The yellow coloration of the Acrysof Natural IOL did not affect the visibility of the RNFL in photographs. CONCLUSIONS: The Acrysof Natural IOL did not affect colour vision in the tested patients, even in the blue region of the spectrum, and can be implanted in patients who need to have normal colour vision for the purposes of their occupation. The Acrysof Natural IOL does not interfere with RNFL photography and can also be used in patients with glaucoma.
