comparison of visual performance with photochromic, yellow and clear intraocular lenses

purpose: to evaluate visual function in patients with different types of light-filtering intraocular lenses (iols) methods: in this prospective comparative clinical study cataract patients with different types of iols in khatam-al-anbia eye hospital, mashhad were enrolled and followed for three months postoperatively. corrected distance visual acuity (cdva), color discrimination under photopic (1000 lux) and mesopic (40 lux) conditions were evaluated with roth 28 hue test. contrast sensitivity testing was then performed with 1000e contrast sensitivity unit (csv-1000e, vector vision) with a constant test luminance level of 85 cd/m2. results: in this study, 47 patients were evaluated with different iols (16 clear, 17 yellow, 14 photochromic). there were no significant differences between the three iols in cdva, contrast sensitivity and mesopic and photopic color vision (p<.05).  conclusion: contrast sensitivity as well as the mesopic and photopic color vision are not different in clear, yellow and photochromic iols.   iranian journal of ophthalmology 201426(3):144-9 © 2014 by the iranian society of ophthalmology
