Cataracts are one of the most common reasons older adults notice their vision changing. Colors look duller, headlights seem to have halos, and reading gets harder in low light. If your eye doctor has mentioned cataract surgery, one of your first questions is probably a practical one: will Medicare pay for it?

The short answer is yes, Original Medicare covers medically necessary cataract surgery. But “covered” does not mean “free,” and there are a few choices during surgery that Medicare does not pay for. This guide walks through what is included, what you can expect to pay, and how your coverage choices as a California Medicare beneficiary fit in. It is educational information only, not medical or financial advice.

What Medicare covers for cataract surgery

Cataract surgery is one of the clearest examples of a service Original Medicare treats as medically necessary rather than cosmetic. When an ophthalmologist determines that a cataract is affecting your vision enough to warrant surgery, Medicare Part B covers the procedure as an outpatient surgery.

Coverage generally includes:

Because cataract surgery falls under Part B, it is handled like other outpatient medical care rather than routine vision care.

What you can expect to pay

Original Medicare does not cover 100% of the cost. After you meet the annual Part B deductible, you generally pay 20% of the Medicare-approved amount as coinsurance, and Medicare pays the rest. The exact deductible amount and approved charges change each year, so for the current figures it is best to check Medicare.gov or your plan documents rather than rely on a number that may be out of date.

How much of that 20% actually comes out of your pocket depends on how you get your Medicare:

This is one of the everyday differences between coverage paths, and it is worth understanding before a procedure rather than after. Our overview of Medicare costs explains how deductibles and coinsurance work across Parts A, B, and D.

What Medicare does not cover

Two upgrades come up often in the surgeon’s office, and neither is covered by Original Medicare:

Premium lenses. Medicare pays for a standard monofocal lens, which corrects vision at one distance. Many patients are offered premium intraocular lenses — multifocal, extended-depth-of-focus, or toric (astigmatism-correcting) lenses — that can reduce the need for glasses afterward. Medicare does not pay the extra cost of these upgraded lenses. That upgrade is an out-of-pocket expense, and it can add a significant amount per eye.

Elective vision correction. Procedures done purely to reduce dependence on glasses, such as LASIK, are considered elective and are not covered.

Cosmetic or convenience extras on the eyeglasses covered after surgery — progressive lenses, anti-glare coatings, transition tints, or premium frames — are also out-of-pocket. Medicare covers the standard lenses and frames; the upgrades are yours to pay.

None of these upgrades are required for a successful surgery. They are optional, and it is entirely reasonable to ask your surgeon what the standard, Medicare-covered option looks like for you.

How this fits into your California coverage choices

Cataract surgery itself is covered the same way nationwide, because Part B is a federal benefit. What differs from person to person is the coverage that sits alongside Part B — and that is where your choices matter.

If you are approaching cataract surgery and are also weighing Medicare Advantage against Medicare Supplement, the cost-sharing on procedures like this is one real-world example to think through. Our guide comparing Medicare Advantage and Medicare Supplement lays out the trade-offs. And if you are new to all of this, the turning 65 guide for Southern California explains how the parts fit together.

Plan lineups, networks, and available benefits vary by county across Southern and Central California, so what works for a neighbor in a different county may not be identical to your options. If you would like help thinking through how a specific plan would handle a procedure like cataract surgery, that is the kind of question an independent broker can walk through with you. You can review how we work and the plans we help with, or browse every guide in our “Does Medicare cover it?” series — including screening colonoscopies, where the same preventive-versus-diagnostic distinction decides what you pay.

When you can change plans

If reviewing your coverage makes you want to switch, timing matters. Most people can make changes during the Annual Enrollment Period (AEP), October 15 to December 7, with changes taking effect January 1. If you are already in a Medicare Advantage plan, the Medicare Advantage Open Enrollment Period (January 1 to March 31) gives you one more chance to change. Outside those windows, special circumstances such as moving may open a Special Enrollment Period.

A cataract diagnosis on its own does not open a special enrollment window, so if plan fit is a concern, note the dates above and plan ahead.

Frequently asked questions

Does Medicare cover cataract surgery in both eyes?
Yes. When surgery on each eye is medically necessary, Part B covers each procedure. The eyes are usually done in separate surgeries a few weeks apart, and cost-sharing applies to each.
Does Medicare pay for the eyeglasses I need after cataract surgery?
Original Medicare covers one pair of standard eyeglasses or one set of contact lenses after cataract surgery, from a Medicare-enrolled supplier. Upgrades like anti-glare coatings, progressive lenses, or premium frames are out-of-pocket.
Will Medicare pay for a premium or multifocal lens?
No. Medicare covers a standard monofocal lens. If you choose a premium lens — multifocal, extended-depth-of-focus, or toric — you pay the additional cost of that upgrade yourself, typically per eye.
How much will cataract surgery cost me out of pocket?
After the Part B deductible, you generally pay 20% coinsurance for the Medicare-approved amount, unless a Medicare Supplement or Medicare Advantage plan changes that. Because the deductible and approved amounts update annually, check Medicare.gov or your plan for current figures.
Does Medicare Advantage cover cataract surgery?
Medicare Advantage plans must cover everything Original Medicare covers, including medically necessary cataract surgery. Your specific copay, coinsurance, and network rules are set by the plan, so review your plan’s benefits.
Does Medicare cover LASIK or laser vision correction?
No. Elective vision correction such as LASIK, done to reduce dependence on glasses rather than to treat a medical condition, is not covered by Medicare.
