What a Waste

Most cataract patients like myself would have some useful vision left. When the sun is out, I can't see much. It's just a yellow mist. At night, I can hardly see anything outside, so I don't go out. Car headlights are just a glare, streetlamps have halos. And I can't see well inside at night under electric lighting. But in the daytime, in a partially lit room, I can still see objects, although cloudy. I want to say, when there is some useful vision left, and when ways of improving the remaining vision existed in the past, it seems such a waste to completely destroy the natural lens in cataract surgery, and replace it by a plastic implant foreign to the eye.
For example, if someone was limping and nonsurgical means existed to improve joint or leg function so that he could walk without a limp again, would a doctor amputate that leg and replace it by a wooden or plastic leg? No? Then why replace the natural lens by a plastic one if the natural lens can be saved. It seems such a waste. Once restored, the natural lens will always outperform an IOL, not to mention the risks of surgery. Tweet
