As some of you know, I recently had a cataract surgery in my right\neye, with a new IOL implant. The cataract developed after a macular\nhole surgery (vitrectomy and 2-month gas bubble), followed by a\nretinal detachment shortly thereafter (another vitrectomy, laser,\ncryotherapy, scleral buckle and another 2-month gas bubble).\n\nBoth surgeries were successful, but resulted in a pucker right above\nthe macula, and a very thick cataract (stage 3), impairing my vision.\nMy myopia also was increased by about 3.5D in the affected eye.\n\nMy good left eye has stage 1 cataract with no significant impact on my\nvision.\n\nMy vision after the cat removal and the IOL was improved\nsignificantly, but will not be correctable to 20/20 due to the retinal\ndamage.\n\nI have read a lot about the brightness of colors following cat\nsurgery, however my experience is somewhat different, given my\nopportunity to compare side-by-side color vision through stage 1\ncataract against clear new IOL.\n\nThe no-cat white is whiter. The no-cat sky is bluer. Some othe light\ncolors are somewhat brighter (as if they were mixed with white). But\nall other colors are more intense through my other eye -\- the yellow\nis yellower, the green is greener, the red is redder, and even the\ndarker blue is bluer through my stage 1 cataract. In addition, my\nnight vision in the no-cat eye is quite poor.\n\nHow could it be? One explanation I have is that I might have lost a\nsubstantial amount of cones due to macular damage. Does it make\nsense? Could it be?\n\nBTW, my color vision in both eyes combined is somewhat in the middle\nand I get both the brightness and the intensity.
