Is there any medical reason to get new prescriptions after IOL implants?

Hawaii (and at least one other state I know of - Texas - and probably others) has a law that you can’t get new prescription eyeglasses or contact lenses with a prescription that is more than a year old.

Since I’m posting in GQ, I’ll spare you all my diatribe about what I think the money-motivated reasons are behind such laws. Instead I will simply ask: since I had IOL replacement, is there any chance my eyeglass prescription will change? Or could I safely get new eyeglasses using the prescription I received after a thorough exam which was conducted about 6 months after the IOL replacement was done?

If you’re that current, I would not get a new exam. There are a number of online eyeglass places that will make you glasses based on your existing information.

A couple are;; (3 actually :blush:).

Your eyes may/will change. My replacements were done back in 91/92. Both eyes up to 20/20 at distance (I was tired of being a 4-eyes and wanted cool sunglasses). Things changed after 20 years; I now wear corrective lenses for distance again.

I’m not current at all - I had IOL replacement about 5 years ago and my last eye exam was about 2-3 years ago. Should I decide I want new eyeglasses, I will need to get an optometrist to make a new prescription.

My question isn’t about “how can I get new eyeglasses without going through the tedium and expense of an eye exam,” it is whether there is a MEDICAL basis for making people who have had IOL replacement get checked annually in order to get new lenses. (Changes after 20 years are in a different category, but getting checked every 12 months? I’m curious if that is justifiable.)

I was very nearsighted and wore glasses from about the 6th grade.I had IOLs implanted during cataract surgery. My surgeon advised against multi focal implants due to pupil size etc.

I need glasses to read and have progressive lenses. I had the implants about 15 years ago and my reading prescription has changed a little as has my distance vision. I can do all my daily activities without glasses unless I need to see clearly closer than about 25".
So there can be additional changes after the implants.

Okay, that’s 2 data points suggesting some change in prescription is possible (though I suspect not much in a year’s time, but who knows).

I’ll add that an eye exam is not only for a lens prescription. They’re also looking for other changes that may occur with or without implanted lenses.

My wife developed some opacity at the back of the lens capsule with required a shot or two with a laser to create an opening. Both eyes about 2 years apart. Also looking for increased fluid pressure in the eye. Macular degeneration can be another issue.

In my opinion it’s a worthwhile exam if you like looking at things.

Thanks GaryM. I’ve been under the care of a retinal specialist for years, mostly thanks to retinal degeneration plus a few other fun things on the side. For a while I had to have thorough exams every 6 months. But they don’t do eyeglass stuff, they leave that to the optometrist.

Sure eyes change. I had a prescription when I was in HS and used the same prescription for about 50 years and it worked fine. Of course, by that time, I was taking my glasses off to read, but so what. Now I have progressives. I do go to the optometrist every year for a general exam and pressure test, but my prescription doesn’t change.

It’s a different situation entirely when you have IOL, though. Of course “normal” eyes will change prescription - but those of us with “bionic” eyes will not experience the same kinds of changes that regular eyes do.

This boggles my mind. I try to put on glasses from HS now that I’m about 20 years removed, and it’s basically like nothing at all. I definitely notice my eyes very very slowly having a harder and harder time seeing distance, and it’s now to the point where “distance” is anything beyond one foot… It’s been happening my entire life, and sometimes I dread just how strong my glasses will eventually have to be; presumably at some point I’ll get some sort of surgery to correct the problem if it’s too far gone, but I don’t really mind wearing glasses so I’m not going to do that unless it’s really the only option.

I think the point is that when you need a new prescription, you know it. You don’t need to be told it by some guaranteed-income-for-optometrist law.

There are a number of reasons why a prescription would change even if the lens was an artificial replacement. Changes in the shape of the cornea (something that I’m experiencing) and movement of the lens implant are two big ones. Even if the prescription doesn’t change, there’s all the vision-threatening stuff that could get picked up at an annual exam, like glaucoma or retinal degeneration or blood supply issues or macular edema.

It’s the same reason that you don’t get to refill your medications an unlimited number of times - someone should be checking to see that the dose that was appropriate in 2015 is still appropriate in 2020.
