Extended Depth of Focus (EDOF) Intraocular Lenses (IOLs) are lens implants designed to provide continuous, high-quality vision at a wide range of distances. These lenses work by enhancing the eye’s ability to focus at various focal points, improving both near and distance vision. EDOF IOLs use advanced optics to create a smooth transition between focal ranges, reducing the need for glasses or contact lenses. Dr. Hu offers this technology to help restore clear, functional vision for daily activities.
Extended Depth of Focus (EDOF) IOLs use advanced optical technology to create a single, continuous range of vision. Unlike traditional lenses, which focus on one specific distance, EDOF IOLs are designed with a unique aspheric surface that enhances the depth of focus.
This minimizes the image distortions often seen with traditional multifocal lenses, providing sharper vision at multiple distances. The result is improved visual clarity at near, intermediate, and far distances, reducing the need for corrective lenses and offering a more natural experience.
EDOF IOLs provide continuous, high-quality vision at various distances. Unlike traditional monofocal lenses, which focus on one specific distance, or multifocal lenses, which divide vision into multiple focal points, EDOF lenses offer a smooth transition between near, intermediate, and far distances. This improves vision quality, especially for those with presbyopia, and reduces the typical glare and halos that can occur with multifocal lenses.
While both EDOF and multifocal IOLs aim to reduce the need for glasses, EDOF lenses provide a more natural and continuous range of vision. Multifocal lenses have distinct zones for near, intermediate, and far vision, which can sometimes cause visual disruptions like glare or halos. EDOF lenses, however, use advanced technology to create a smooth transition between focal points, reducing visual disturbances and providing sharper clarity across all distances.
One of the main benefits of EDOF IOLs is their ability to reduce glare and halos, which are common side effects of traditional multifocal lenses. The continuous focus provided by EDOF lenses allows for smoother transitions between focal points, minimizing visual disturbances, particularly in low-light conditions. While every patient’s experience is unique, most individuals report improved clarity with minimal glare and halo effects compared to older technologies.
Most patients experience a noticeable improvement in vision within a few days to weeks after the procedure. The brain needs time to adapt to the new visual experience provided by the EDOF lenses. While many patients achieve excellent vision soon after surgery, it’s common to experience mild fluctuations in focus during the initial adjustment period.
Although EDOF IOLs significantly reduce or eliminate the need for glasses, some patients may still require them for specific tasks, such as reading small print or engaging in detailed close-up work. However, many individuals can perform most activities without glasses or contacts. During your consultation, Dr. Hu will help set realistic expectations based on your unique visual needs.
