Extended Depth of Focus IOL

Procedure

Extended Depth of Focus IOLs

Extended Depth of Focus IOLs (EDF) provide a continuous range of vision allowing you to see clearly at intermediate and far distances and have functional vision for near distances.

An Overview: Extended Depth of Focus (EDF)

During Cataract Surgery or Refractive Lens Exchange (RLE), the crystalline lens is removed and replaced with an Intraocular Lens (IOL), through a safe and effective procedure. The goal of the IOL is to give you the best visual outcome based on your lifestyle and your eyes’ shape and health.

While there are many IOL options, some, like the monofocal lens, will only correct vision at one distance and may require you to wear glasses at other distances. Trifocal lenses correct the vision at multiple distances but require the eye to refocus when shifting between each distance. Also, the perception of halos around lights has been reported with multifocal lenses.

Extended Depth of Focus IOLs can correct far, and intermediate distances vision, as well as astigmatism. The EDF technology brings more extension of focus for good near-distance vision.

The EDF IOL is revolutionary because in addition to correcting vision at multiple distances, it can also reduce some of the symptoms commonly experienced with multifocal IOLs, such as glare and halos around lights.

At a Glance:

EDF technology brings more extension of focus for good near-distance vision. Also, the lenses do not create halos in the vision.

EDF Lenses:

Light Adjustable Lens (LAL)

Light Adjustable Lens (LAL)
  • Designed using technology that earned the 2005 Nobel Prize in Chemistry
  • EDF technology is used in the Light Adjustable Lens (LAL), a new generation of Intraocular Lenses available at CODET Vision Institute. This lens provides greater accuracy in the refraction with its adjustability after being implanted.
  • Continuous range of vision allowing you to see clearly at intermediate and
    far distances and have functional vision for near distances.
  • Corrects Astigmatism
  • Glare and halo free vision

Vivity Lens

  • Delivers monofocal-quality distance (far) with excellent intermediate (at arm’s length) and functional near vision (up close)
  • Corrects Astigmatism
  • Glare and halo free vision
Laser Cataract Surgery

Why CODET for EDF?

The EDF technology for Intraocular lenses is available at CODET with the Light Adjustable Lens (LAL) and the Vivity Lens.

CODET Vision Institute provides our experienced doctors with advanced, proven technology and the finest surgery rooms and equipment.

CODET is a leader among ophthalmic institutions and has the unmatched experience utilizing Light Adjustable Lens. Dr. Arturo Chayet, Medical Director of CODET, performed the first LAL surgery in the world in 2002. Since that time, he and CODET have been instrumental in developing the LAL technology.

About our Technology and Facilities

One of the keys to successful IOL implantation is pairing it with additional state-of-the art technology:

  • Diagnostics: Intraocular Lens Calculation with the Heidelberg Anterion OCT
  • Surgical: Your surgeon will use the Ziemer Femto LDV Z8 Femtosecond Laser on a case by case basis as needed, at no extra cost
  • The LAL procedure uses the RxSight Light Delivery Device, which allows your doctor to non-invasively deliver UV light to your Light Adjustable Lenses.
