Lens Implant Options

During cataract surgery, your cloudy lens is replaced with a clear artificial lens called an intraocular lens (IOL). The type you choose affects how much you'll rely on glasses afterward.

Your options

Monofocal

Focuses clearly at one distance, usually far away.

After surgery
Reading glasses for close-up. You may also need glasses for distance if you have astigmatism.
Trade-offs
The lowest chance of glare or halos at night.
Cost
Covered by insurance

Toric

Corrects astigmatism, a common uneven curve of the eye that blurs vision at every distance.

After surgery
Clear distance vision without glasses for many people. Usually reading glasses for close-up.
Trade-offs
The lens has to be lined up precisely along your astigmatism.
Cost
Added out-of-pocket cost

Extended depth of focus (EDOF)

Stretches focus from far away to arm's length, such as a computer screen or a car dashboard.

After surgery
Less need for glasses for most daily tasks. You may still want readers for small print.
Trade-offs
Some people notice mild halos around lights at night.
Cost
Added out-of-pocket cost

Multifocal

Gives focus at distance and up close, and often in between.

After surgery
The least need for glasses, including for reading.
Trade-offs
More chance of halos and glare at night, and a few weeks to months for your brain to adjust.
Cost
Added out-of-pocket cost

EDOF and multifocal lenses also come in toric versions for people with astigmatism. Another approach, monovision, sets one eye for distance and the other for near using standard lenses. It works best for people who have used monovision contact lenses before.

How to decide

  • How much do you want to avoid glasses? If you don't mind reading glasses, a monofocal lens is an excellent choice.
  • Do you drive a lot at night? If halos would bother you, a monofocal or toric lens may suit you better than a multifocal.
  • What does your eye health allow? Conditions such as macular degeneration or advanced glaucoma can make some lenses a poor fit. Dr. Hwang will tell you which options suit your eyes.

Cost

Medicare and other health plans cover cataract surgery with a standard monofocal lens. Toric, EDOF and multifocal lenses have an added out-of-pocket cost for the lens and the extra testing they need. We'll give you the exact cost in writing before you decide.

Common questions

Can a lens implant wear out?

No. Lens implants are made to last for the rest of your life.

Will I be able to feel the lens?

No. Once it's in place, you won't feel or see the implant.

Can each eye get a different lens?

Sometimes, for example with monovision. Dr. Hwang will recommend what works best for your eyes and your daily life.
