Somebody handed you a sheet with four lens names on it and asked you to pick one. You've never heard of any of them, you're guessing at what your vision would be like with each, and some of them cost extra. So you're wondering whether the extra is worth it.
The video below is the conversation I'd have with you in the exam room. Eleven minutes, unhurried. Watch it before your lens appointment, and if you can, watch it with whoever's coming with you.
What to listen for
- The question to ask instead of "which lens is best." Once you have it, the four options sort themselves.
- The four lenses, set apart by one thing you already know about yourself.
- Why the lens that does the most isn't automatically the one to pick, and who's happiest with it anyway.
- My mom and my dad. Same house, two very different daily needs, and what that meant for their lenses.
- How the money actually works, and a straight answer to "is this an upsell?"
- Two short lists of questions. One is about your eye. The other is about your surgeon.
What didn't make the cut
Some extra things I didn't have time to mention in the video.
Do this for one week before your appointment. Keep a note on your phone. Every time your vision gets in your way, write down what you were doing and how far away it was. Backing out of the driveway. A price tag. A grandchild's face across the table. At the end of the week you'll have a list of what your eyes actually do all day, not what you remember them doing. Bring it. It's the most useful thing you can carry into that conversation.
You have the time. Cataract surgery is elective. In most cases you have a window of time to decide. The decision people tend to regret is the one made in four minutes because they felt put on the spot. Take the week. Then come back and have the conversation.
What's on the bill, in writing. The medical part of cataract surgery, removing the cataract and placing a basic lens, is what a plan generally covers. One line that got trimmed from the video: some of the laser-assisted steps of surgery can also sit on the part you pay for, because they're aimed at your glasses prescription rather than at the cataract. Ask for the list of what's covered and what isn't before you decide.
Have realistic expectations. Not all people who don't want to wear glasses are a good fit for a lens that gets them there. The one answer that gives me pause is "I want to be free of glasses no matter what," because no lens can promise that, and a decision built on a promise is the kind that disappoints. Say instead what you'd most like to do without glasses, and what you could live with. That's a request a surgeon can actually meet.
The lens types, in plain words
A few words you'll hear in the room:
- Monofocal. One focus point. Far, or arm's length, or near. You pick which.
- Multifocal. More than one focus point. Far, arm's length and near from one lens.
- Extended depth of focus (EDOF). One focus point, stretched. Far through arm's length, and some near.
- Toric. Any of the above, with astigmatism correction built in.
- Astigmatism. The front of the eye isn't perfectly round, so edges look smeared or shadowed.
- Presbyopia. The eye's own lens stops changing focus, usually in your forties. It's why reading glasses appear.
- Light adjustable lens. A lens whose power is fine-tuned with light after surgery.
For night driving
A monofocal lens set for distance gives the crispest night vision with the least glare, which is why it suits people who drive a lot after dark or work in low light. If you have astigmatism, the toric version corrects it. You'll wear glasses for close work and reading. The basic version is the one most plans cover.
For astigmatism
If you have astigmatism, a toric lens corrects it at the same time as the cataract comes out, and it comes in monofocal, extended depth of focus and multifocal versions. Once in a while the lens shifts in the first hours or days and needs a small repositioning to sit exactly right. In a 2026 review of 1,564 eyes, 12 needed that. The astigmatism part is usually not covered by insurance.
For reading without glasses
A multifocal lens covers far, arm's length and near from one lens, so readers become an occasional thing instead of a constant one. It gives the widest range of any lens on this page. In exchange, some people see halos around lights at night, most notice a few weeks of settling in, and it needs a healthy eye to work well, so the screening beforehand is more thorough. Most plans don't cover it. There's a separate guide to the multifocal lenses if that's the direction you're leaning.
An extended depth of focus lens is the middle ground. It covers far through arm's length with fewer night-time halos than a multifocal, and you keep readers for small print. Not every extended depth of focus lens behaves the same at night, though. Some designs, Vivity is one, cause fewer halos than others, Symfony is one, so it's worth asking which design your surgeon has in mind.
Toric and extended depth of focus lenses also do their best work in an eye with a healthy cornea and a healthy retina, which is part of what the measurements before surgery are checking.
For one eye far, one eye near
Monovision sets one eye for distance and the other for near, and your brain uses whichever it needs. It works well for people who already lived with it in contact lenses or after LASIK, and about 9 in 10 people who try it settle into it. Starting it from scratch is harder, depth perception can suffer, and some people want glasses for night driving. It can be done with monofocal, extended depth of focus or light adjustable lenses.
For fine-tuning after surgery
A light adjustable lens goes in like any other lens. In the weeks afterward its power is adjusted with a series of light treatments, then locked in. That makes it useful for eyes where the measurements are less predictable, which includes eyes that have had LASIK, PRK or RK. Results in those eyes are still a little less predictable than in an eye that's never had surgery. The adjustable lens narrows that gap rather than closing it. It means several extra visits, and most plans don't cover it.
Side by side
| Monofocal | Toric | Extended depth of focus | Multifocal | Light adjustable | |
|---|---|---|---|---|---|
| Sharp without glasses | Far | Far, with astigmatism corrected | Far and arm's length | Far, arm's length and near | Far, fine-tuned after surgery |
| Glasses afterward | Arm's length and near | Arm's length and near | Small print | Minimal readers | Arm's length and near |
| Night glare and halos | Least | Least | Some, depending on the design | Most likely | Least |
| Usually covered by insurance | Yes, the basic version | The astigmatism part, no | No | No | No |

When to see an eye doctor
You don't need to rush this decision. A cataract isn't damaging anything while it sits there, and a routine exam is the right pace for it. The reasons to be seen sooner are the usual ones: a sudden drop in vision, new flashes or a shower of floaters, a curtain over part of your sight, or eye pain. Those aren't cataract, and they shouldn't wait.
Common questions
What lens do most people choose for cataract surgery?
Most people, about 86 in every 100, get a standard monofocal lens, because it's the one insurance and Medicare cover, and they wear glasses afterward the way they did before. People who want fewer glasses choose a lens with astigmatism correction, an extended depth of focus lens, or a multifocal. There's no wrong pick. The right one depends on how you spend your day and how you feel about glasses.
How do they know what lens to put in after cataract surgery?
Two things. Measurements of your eye, which set the lens power, and a conversation about your day, which sets the type. Your surgeon also checks your cornea, retina, optic nerve, dry eye and astigmatism, because any one of them can change which lens makes sense. The more clearly you can say what you'd like to do without glasses, the better that conversation goes.
Which lens is best for cataract surgery, monofocal or multifocal?
Neither is best. A monofocal gives the crispest vision at one distance with the least night glare, and you wear glasses for the rest. A multifocal covers far, middle and near so you reach for readers far less, and in exchange some people see halos around lights at night and need a few weeks to adjust. It also needs a healthy eye to work well. Pick the trade you'd rather live with.
Is it possible to put the wrong lens in for cataract surgery?
Your lens power comes from measurements taken before surgery, and the lens is checked against them more than once on the day. Before anything starts, the whole team stops for a time-out to confirm the right patient, the right eye, the right procedure and the right lens. That's standard practice everywhere. If a result does land a little off target, it can usually be fine-tuned afterward.
Do I have to pick my lens the same day?
No. Cataract surgery is elective, and in most cases there's no clock on it. Take the measurements and the printout home, think about your day, talk it over with someone you trust, and come back with questions. A decision made under pressure is the one people regret. A week's thought costs you nothing.
The next decision
The video ends on a question: which lens did I pick for my mom, and what did I tell my dad? Two people in the same house, two different answers, and the reasons are the whole point. That's its own video: I Did My Mom's Cataract Surgery. Dad Just Got My Advice.
