How does interocular lens affect eye color?

It doesn't. The eye color is determined by the pigmentation of the iris. The intraocular lens is placed behind the iris after removal of the cloudy lens (cataract). When you are looking at (or through) the lens, you are seeing the pupil of the eye, which appears dark. Some types of lens implants can cause some reflections or glistening appearance, but they do not change eye color.
No color change. Intraocular lens is placed behind the iris and its a clear lens. It does not effect the color of the iris. But it may sparkle in certain light.
Shiny eyes. They do not change color of the eyes people may notice a sparkle.
