Extended depth of focus lenses are intraocular lens implants that provide a continuous range of vision from distance to intermediate, with some support for near tasks, while aiming to minimise glare and halos.
How EDOF lenses differ from multifocals
Instead of distinct distance and near focal points, EDOF lenses stretch the focus into an elongated zone. This can give smoother vision for activities like driving, computer work, and shopping, with fewer visual side effects for many people.
- Often provide excellent distance and arm’s length vision
- Many everyday tasks can be done without glasses
- Very fine print may still need simple reading spectacles
- May suit those worried about night-time halos from traditional multifocals
Suitability and real world experience
EDOF lenses work best in healthy eyes with regular corneas and no significant retinal disease. A detailed consultation helps decide whether your priorities are maximum spectacle independence or the best possible contrast and night vision.
- Ideal for people who value driving and screen use with minimal visual phenomena
- Adaptation is usually gentle, with the brain learning the new focus pattern
- Glare and halos can still occur but are often milder than with multifocals
- Regular follow up ensures the implant is well positioned and eyes remain comfortable
