OR, two, get it done early. You will heal faster, you'll enjoy more years of better vision, You'll be more comfortable driving at night, your sharper vision acuity will make travel/sightseeing more enjoyable, You can stop wearing your 'regular' glasses, opting for either multi-focal (more expensive) lenses, or using reading glasses.
I went with getting it done earlier, preferring more years of clear sight over the alternative of a longer period of gradually worsening vision.
I went with the plain-vanilla single vision lens implants. I have to wear glasses anyway because I'm crosseyed & I need prismatic lenses to correct for that, so there was no need to get tricky expensive multi-focus high-tech lens implants. Medicare plus medigap insurance covered the full cost.
The prospect of getting the 1st cataract operation was nervous-making, bigtime. I mean, the idea of doctors coming at my eyeball with scalpels, etc., was semi-frightening at best & terrifying at worst. As it happened, there was nothing to it (for the patient -- I'm sure the doctors & nurses were working at an intense pace). The 2nd operation a year or so later inspired zero nervousness. Both procedures were successful.
There was 1 minor complication after another year went by. According to the eye doctor, in 30 percent of patients who have had cataract surgery, the membrane encapsulating & supporting the implanted lens starts to darken & cause visual impairment. I am part of the 30 percent, although I had not noticed any worsening vision -- the doctor detected it during a routine follow-up exam. (I guess it's subtle & gradual.) The doctor said mine had already darkened & would get worse if left alone, but a quick laser procedure would take care of it, so I signed up for that.
The laser treatment was done at the same eye surgery center where I had the cataract operations, but it involved hardly any preparation (unlike the cataract operations, which involved plenty). I wasn't even lying down. For the laser procedure, the doctor had me get seated in front of a device resembling those instruments the ophthalmologists use to look at the inner recesses of the eyeball, & prop my chin on the chin rest. He had me gaze at a red light with eyes wide open. He pressed a button & a quick beep sounded -- maybe 5-6 times. That took all of 9-10 seconds. "All done," the doctor said. It remains to be seen whether I'll be going through the same thing for the other eye at some point.
Incidentally, the suburban eye surgery center is right next door to a suburban colorectal surgery center, so was important to pay attention to which door I was about to go in. So far, so good.
