 But K2 Vision RLE will. It's not a question of if your lens becomes dysfunctional. It's when. At that point, you'll need reading glasses and could benefit from refractive lens exchange, a permanent solution to distance, intermediate, and near vision problems. In other words, no glasses, no contacts, and no readers. And no cataracts. Exactly. After K2 Vision RLE, you will never develop a cataract.
