As one meta-analysis put it:
It’s estimated that an increase of one hour per day of outdoor time could reduce the occurrence of myopia in children by 45%.
Make sure your kids spend time outside, folks!

Well, yeah, I’m old, and there were cataracts in both eyes, but one went bad real fast, over the course of a few months. The doc told me that it’s kinda rare, but it happens. What was weird is that it only happened in one eye, so at least I could see with my one good eye, but if it happened to that eye too, before I could get the surgery, I’d be screwed. I literally wouldn’t be able to see well enough to drive, read, anything.
So the new lens corrected for any bad eyesight, more or less. I haven’t had it tested now that it’s fully healed, but it probably isn’t perfect 20/20, but it’s close. I have a contact in my other eye, which is still at a 9, so very bad. It also has a light cataract.
Now I can see the difference between the two eyes. In my new eye, colors are brighter and sharper. In my other, cataract eye, colors are slightly, but noticeably muted. I probably wouldn’t even have noticed it, if I didn’t have the new eye for comparison.
I’ve also noticed that late at night, when I’m tired but still watching TV, I get double vision. I have to consciously focus. The doc warned me that having a good eye, and a contact lens eye would mess with my vision, and I think this is what he was talking about.
The doc said that now that I’ve had one done, the insurance will probably spring for the second one, even if it isn’t necessary yet. That means I’ll have nearly perfect vision, and maybe need reading glasses. I use reading glasses with my new eye, but if I don’t have them, it isn’t a big deal, I see well enough for most stuff.
Sorry to yak so much about it, but It’s kind of exciting, being able to see so well for the first time, as an old person, and I don’t really have anyone else to tell it to that would care.
That’s fascinating. Is it typical for cataract surgery to cause near 20-20 vision or is this something that just happened to you because you have a unique eye shape?
No, the doc said this would get pretty close. I don’t think they can ever predict exactly where your vision is going to land, but he knew it would be close enough for reading glasses, which I never go anywhere without anyway, even with contacts. They are replacing your lens, so why replace with just a clear lens that is the same as your poor vision, that has to be corrected with supplemental lenses, when you can just replace the lens with a correct one, and fix the entire problem at once.
Of course, an immoral eye doctor might want to fix the blurry cataract, but keep your eyesight poor so they can continue to sell you glasses and contacts.
So I was expecting an improvement, and it certainly got darn close. Closer than I’ve experienced for most of my life.
BTW, it also wasn’t really painful at all. It was uncomfortable the first day, but not itchy or painful, much less so the next day, and was pretty normal in 48 hours. I took a Tylenol/Advil combo, and drops they gave me.
They can’t predict with 100% accuracy, because vision isn’t a completely objective matter as it also takes into account your brain’s interpretation of the image, but they can get pretty close. The exams you took probably measured your eye’s axial length, your cornea’s keratometry, diameter and other measurements.
Your ophthalmologist then selects the formula that best suits your eye (there’s different mathematical models for different cases of myopia, hypermetropia and how extreme they are) and then the lens’ power is calculated according to the measurements that were taken. Usually the device that takes your exam already does like 80% of the job (in the mathematical side of things), but your doctor uses their criteria to define the final IOL and from where it’ll be inserted during surgery*.
It’s pretty cool to take that exam. In my country I used to take it for patients that were going into eye surgery.
* It usually means a little bit more math
Is this procedure ever performed on someone with healthy cataracts to improve their eyesight?
Amazing! Congratulations on your new eyesight!
