Extended Depth of Focus (EDOF) Lenses for Cataract Surgery
Advanced Technology Aimed at Enhancing Vision Across Multiple Distances
At Harvard Eye Associates, we are committed to helping patients achieve their best possible vision after cataract surgery. One of today’s most advanced solutions is the Extended Depth of Focus (EDOF) intraocular lens (IOL), a premium lens option designed to provide high-quality, continuous vision from far to intermediate distances, with functional near vision.
What Is Extended Depth of Focus?
Extended Depth of Focus IOLs use innovative optical technology to elongate the focus range, allowing the eye to maintain sharp, seamless vision across more distances than a standard monofocal lens. Unlike multifocal lenses that create multiple focal points, EDOF lenses offer a smooth visual transition, reducing the visual disturbances that some patients may experience with other premium lenses.
Benefits of Extended Depth of Focus Lenses
Patients often choose EDOF lenses because they provide a strong balance of clarity, comfort, and spectacle independence. Key benefits include:
- Good distance vision for activities such as driving, watching TV, and enjoying outdoor recreation
- Excellent intermediate vision, ideal for computer work, cooking, and daily tasks
- Functional near vision with reduced dependence on reading glasses
- Lower risk of halos and glare compared to some multifocal lenses
- Enhanced depth perception for a more natural visual experience
- Advanced lens technology backed by strong clinical performance
