A Guide To
Cataract Lenses

No single lens is best for everyone. Your surgeon considers your eye health, measurements, daily activities, and budget. At Barnet Dulaney Perkins Eye Center, a cataract evaluation helps you compare options based on your priorities, including reading, computer work, and night driving.

You may still need glasses, regardless of which lens you choose. Monofocal lenses focus at one distance, so choosing distance vision usually means wearing reading glasses. Other lens designs can reduce your dependence on glasses, but none guarantees glasses-free vision for every task. The American Academy of Ophthalmology explains these differences in lenses.

Multifocal lenses provide more than one focus. Trifocal lenses include distance, intermediate, and near focus. Extended depth-of-focus, or EDOF, lenses extend the range of focus, generally emphasizing distance and intermediate vision. Near vision varies by design, and reading glasses may still be necessary. Each option has tradeoffs involving visual range, contrast, and halos.

Yes. Toric lenses can correct corneal astigmatism during cataract surgery. “Toric” describes the astigmatism-correcting feature, not the number of focusing distances. Some monofocal and presbyopia-correcting lenses have toric versions. Your surgeon measures your cornea to determine whether this correction would help.

The Light Adjustable Lens allows your doctor to refine its focusing power after surgery through a series of office-based light treatments. It requires additional appointments and special UV-protective glasses during the adjustment period. Follow your care team’s instructions, including when you can stop wearing the glasses. RxSight’s patient guidance explains these requirements.

Tell your surgeon that night driving is a priority. Monofocal lenses may suit patients who prioritize contrast and fewer visual disturbances. Multifocal and some EDOF designs can produce halos or glare, although experiences vary. The American Academy of Ophthalmology includes night driving as one of the factors to consider when choosing a lens.

Possibly, but your diagnosis and the extent of any vision damage matter. Some lens designs may be unsuitable when an eye condition already affects contrast or central vision. Your surgeon will explain which options offer realistic benefits without adding unnecessary visual tradeoffs.

Medicare and many insurance plans cover a conventional monofocal lens as part of covered cataract surgery. Deductibles and other out-of-pocket costs may still apply. Choosing additional vision-correction features can involve charges that your plan does not cover. Review Medicare’s cataract surgery coverage and request an itemized estimate showing covered services and optional upgrades.
