    Recalibrating a PJ after cataract surgery

    On Tuesday I had cataract surgery on my left eye and had a new lens implant. This new lens has changed how I see color from the left eye and therefore has some affect on vision and how I perceive color when viewing a color picture with both eyes. The new lens pushes blue, so reds are pinkier and greens are wanting. The Doc says this is normal as the new lens implants have UV blockers or something to that effect. Watching a movie now causes me to see pinkier fleshtones and a pinkish tint to whites. So I had to make a few adjustments in the Gains and Bias. All I really had to do to get things back to normal ( for me, anyway) was give the green a little boost. I have only made this adjustment in one setting that I alone will use. When I have company/and or my wife, I go back to my old D65 setting.

    I know most of you guys out there are younger than me and probably years away from cataract problems, but just wanted you to know that if you do have cataract surgery you may also have to recalibrate. A real bummer, isn't it.

    A little curious - If the new lens made you see projected images with these color changes, wouldn't the actual objects in the real world also suffer from the color changes?

    So in time, won't the new color response of your vision become normal looking to you and require you to re-calibrate again back to your original settings?

    I've had some retinal problems with my left eye, and at times, the color vision in that eye gives everything a washed-out, less saturated look. Lately it has returned to normal though. I tend to do color calibrations with only my right eye because of this.

      Actually Brandon, everything changed. My white fridge looks whiter, but with a slight bluish look to it, so, yes I perceive color differently period. Now, over time this may change. In the meantime , though, I am only bothered by the fact that video images do not look right to me anymore.

      Funny thing is, the Doc said that most people say they find colors more vibrant after the lens implant. And colors do become more vibrant. But this is not necessarily a good thing if you have been playing around with projectors for 15 years, like i have, and want natural looking black and white images for your old classical movie collection.

        George,

        Give you eye and your brain time to adjust to the new implant.

          That sounds like good advice, Thomas.
