Multifocal lenses are intraocular lens implants designed to provide focus at more than one distance after cataract or lens replacement surgery, reducing reliance on glasses.
How multifocal lenses work
Unlike standard monofocal lenses that focus mainly at one distance, multifocal designs divide incoming light between distance, intermediate, and near focal points. This allows many daily tasks to be done without spectacles.
- Helpful for reading, computer work, and driving without changing glasses
- Available in different designs, including trifocal and extended range options
- Best results occur when both eyes receive appropriately matched implants
- Careful assessment ensures suitability for your lifestyle and eye health
Benefits, trade-offs, and adaptation
Many people enjoy greater freedom from glasses, but splitting light can reduce contrast and cause halos or glare around lights, especially at night. The brain usually adapts over time, learning to use the information from both eyes efficiently.
- Good lighting and realistic expectations are important in the early months
- Some patients may still prefer weak glasses for particular fine tasks
- Not ideal if you have significant retinal disease or very demanding night driving needs
- Discuss personal goals and hobbies with your surgeon before choosing
