AT ELANA trifocal intraocular lenses are advanced artificial lenses used during cataract or lens replacement surgery. They aim to reduce dependence on glasses for far, intermediate, and near vision.
How AT ELANA lenses work
These lenses sit inside the eye, replacing the cloudy natural lens. Their trifocal design splits light into different focal points so you can focus at multiple distances.
- Distance focus supports tasks like driving and watching television.
- Intermediate focus helps with computer work and everyday indoor activities.
- Near focus assists with reading, phones, and labels.
- The lens is permanent and does not usually need replacement.
- Results depend on eye health, tear film quality, and accurate measurements.
What patients should consider
Trifocal lenses offer more spectacle freedom but are not perfect for everyone. Some people notice haloes or glare around lights, especially at night, which often reduce with time.
- A detailed assessment checks suitability, including corneal shape and retinal health.
- Astigmatism may need extra correction with laser or specific lens designs.
- Good lighting and patience with adaptation improve early reading comfort.
- Night driving may feel different at first while the brain adapts.
- Discuss your lifestyle and visual priorities carefully with your surgeon.
