Another, related condition of cataracts is a secondary effect, whereby the membrane behind the lens becomes clouded. This happened to me (the ophthalmologist had warned me it could), and the vision in my left eye became progressively blurred fairly quickly. Two days ago, I had a laser procedure which, in essence, burns a hole through the clouded membrane, allowing light to pass through unimpeded. It works! Vision in the left eye is restored and is as good as it had ever been. So far, no side effects, and I am very pleased with the improvement. Just FYI, fellow old-timers.
