You were told your cataract isn't bad enough yet. Or you were told it's time, and something about it didn't sit right. I see both of you every week, and you've usually been handed the same thing to decide with: a line on an eye chart.
The video below is the conversation I'd have with you if you were sitting across from me. Nine minutes. Watch it before you decide anything.
What to listen for
Not a full summary but what to listen for in the video:
- The test every eye office in the country uses, and the one thing about your vision it can't see.
- The three things I rule out before I'll blame a cataract for anything.
- Whether there's a deadline. There's a straight answer in there.
- The decision that comes right after this one, which is the one people regret getting wrong.
If your eye doctor gave your cataract a stage or a grade and you want to know what the words mean, the stages article walks through them. This page is about the other question: what to do with that information.
Three things I didn't cover in the video
Every video gets trimmed, here are three more things you should know.
Going early isn't a mistake, but there is something you should know. If you're already seeing fairly well and we operate, there's less room for it to get better. The people who go in with the least to gain are the ones most likely to come out thinking, is that it? That isn't the surgery failing. It's the gap between what somebody pictured and what was on offer, and nobody closed it beforehand. The numbers don't punish going early when the cataract is already costing you something: people who had surgery while still reading 20/30 or better gained measurably on everyday tasks and were still ahead a year later. Early can be right. It needs somebody to tell you plainly what you're buying.
The dementia link has a control group. In the video I mention that cataract surgery is tied to a lower rate of dementia and that nobody has shown the surgery causes it. What I cut is why I take the signal seriously anyway. The same study looked at people who had glaucoma surgery. Glaucoma surgery doesn't give your vision back, and in that group there was no effect. The link tracks with getting sight back, not with having an operation. Still an association. A more interesting one.
And one line I meant to say and didn't. If you were told it's time and you're still not sure, you're allowed to say not yet. Being told it's time is a recommendation.
When to see an eye doctor
If your vision is getting in the way and nobody has looked at the whole eye recently, book the exam. What a proper look includes is in the video.
Some things shouldn't wait for a routine visit. A sudden drop in vision, new flashes of light, a curtain or shadow across your sight, or eye pain need to be seen sooner rather than later.
Common questions
Can a cataract be too early to remove?
Not by its grade. The evidence doesn't punish going early when the cataract is already costing you something. What it punishes is going in with a picture of the result that nobody checked with you first. That conversation is most of the video.
Do I have to wait until the cataract is ripe?
No. That idea belongs to an older generation of surgery, when the operation needed a hard, dense lens to work on. Today a dense cataract makes the operation harder, not easier. What I look at instead of ripeness is in the video.
The next decision
The video ends on the question that comes right after this one, and it's the one people wish they'd thought harder about. Which lens goes in your eye. I made a whole video on it: 4 Cataract Lens Implant Options: Which One Should You Choose?
