EDOF IOLs
Extended depth of focus lenses, often discussed as their own category.
EDOF stands for "extended depth of focus." These intraocular lenses (IOLs) are designed to provide a continuous range of focus rather than distinct focal points, and they are frequently discussed as a category of their own.
The general idea behind EDOF
Where a multifocal lens is built around separate focal points, an EDOF design aims to stretch a single, extended zone of focus. People often bring EDOF into conversations about intermediate vision, though how any lens performs across ranges varies by design and by individual. Some people compare EDOF and multifocal approaches when thinking about the range they want and the tradeoffs they are willing to consider.
Discussion points people often raise
- How is the range of focus described for a given EDOF design?
- What visual effects, if any, are part of the tradeoff?
- How does EDOF compare with multifocal or monofocal options for me?
- Is a toric version relevant if astigmatism is part of my situation?
Results vary
Individual experiences with any lens category differ. A qualified ophthalmologist can explain whether EDOF options may apply to your individual situation.
