Full-range trifocal lens
A trifocal lens provides three focal ranges — distance, computer range and reading — with the greatest potential to reduce how often you need glasses.
What to expect
A trifocal lens splits incoming light between three focal ranges — distance, computer range and reading. This is why it can do more than other lenses, and also why some people notice rings or starbursts around headlights at night.
Most people adapt to these effects over weeks to months.
Some people do not adapt. This is the lens where expectations matter most, because a patient who is surprised after surgery is the outcome this page exists to prevent.
What it does well
- Provides distance, computer and reading ranges
- Greatest potential to reduce glasses dependence
- Strong option when maximum visual range is the highest priority
Trade-offs to discuss with your surgeon
- Halos, glare or starbursts may occur
- Night vision may be less crisp than with a monofocal lens
- Not appropriate for every eye — the surgeon determines candidacy
Halos and starbursts usually look like soft rings or circles of light around street lamps and headlights, sometimes with faint streaks. They are more noticeable in dark settings such as night driving, and tend to be most noticeable in the first weeks after surgery.
Questions to ask your surgeon
- How much night driving do I do, and does that change your advice?
- What happens if I do not adapt to the night-time effects?
- Is my eye a good candidate — are there conditions that would rule this out?
- Do my measurements show astigmatism, and would you use a toric version?

About astigmatism
If your measurements show meaningful astigmatism, your surgeon may recommend a toric version of the selected lens category.
Your surgeon may also discuss laser-assisted cataract surgery. The laser can help perform certain steps with added precision, soften the cataract before removal, and treat small amounts of astigmatism. It is commonly included with advanced lens packages at participating practices.
Some advanced lens and laser options involve costs that are not covered by insurance. Exact pricing depends on the option selected and will be explained by your surgical scheduler.
This educational tool does not diagnose eye conditions, determine whether you are a candidate for a specific lens, or replace a discussion with your surgeon. Your surgeon will recommend appropriate options after examining your eyes.
