Question

What are extended depth of focus intraocular lenses EDOF)?

Hint:

EDOF lenses provide a continuous range of vision with less visual disturbance compared to traditional multifocal lenses, making them an ideal choice for cataract patients who seek a broader range of vision.

Answer 1

Extended Depth of Focus (EDOF) intraocular lenses are a type of multifocal intraocular lens (IOL) designed to improve visual acuity across a range of distances, particularly benefiting patients who have undergone cataract surgery. EDOF lenses are engineered to extend the depth of focus, providing better near, intermediate, and distance vision without the abrupt visual jumps seen with traditional multifocal lenses.
- EDOF lenses are typically used in patients who wish to achieve functional vision at multiple distances with a focus on intermediate vision (such as for computer use), while minimizing the visual disturbances like halos or glare that are common with traditional multifocal IOLs.
