⁵S.B. Ankara Eğitim ve Araştırma Hastanesi 1. Göz Kliniği Klinik Şefi, Ankara, Uzm. Dr. Purpose: To compare two groups of patients who underwent implantation of blue filtering-yellow-pigmented intraocular lens (IOL) (Alcon AcrySof SN60AT-Natural) and nonpigmented IOL (Alcon AcrySof SA60AT) in terms of: Color perception under mesopic and photopic conditions and contrast sensitivity under mesopic conditions.
Materials and Methods: Pseuodophakic patients with a visual acuity better than +0.1 LogMAR and successful color vision test with Ishihara plates in the post-operative 3rd month were included in this study: 16 eyes of 15 patients (8 male, 7 female) with yellow-pigmented IOL and 8 eyes of 8 patients(4 male, 4 female) with non-pigmented IOL were tested. Mesopic (2.4-3.1 cd/m²) and photopic (82-86 cd/ m²) conditions were standardized and patients were tested with Farnsworth-Munsell (FM) 100-Hue test under these conditions. Tri-Va contrast sensitivity test was performed under mesopic conditions.
Results: The contrast sensitivity results of both groups were similar. The error scores and the square root of the error scores of FM-100 Hue tests were lower in patients with yellow-pigmented IOLs. However these differences were not statistically significant.
Conclusion: The patients with yellow-pigmented IOLs have a similar contrast sensitivity performance compare to patients with non-pigmented IOLs, under mesopic conditions. The color vision performance of patients with yellow-pigmented IOLs is as good as patients with non-pigmented IOLs, both under mesopic and photopic conditions. The visual performance with the yellow-pigmented IOLs is similar to nonpigmented IOLs under non-ideal conditions. Keywords : intraocular lens, color vision, contrast sensitivity, photopic, mesopic
