How EDF Technology in the Light Adjustable Lens Works

Dr. Arturo Chayet of CODET Vision Institute discusses Extended Depth of Focus (EDF) technology in the Light Adjustable Lens in a new video. EDF is effective for near, far, and intermediate distances and provides halo-free vision.

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.

For these procedures, there are two different types of Intraocular Lenses: monofocal and trifocal.

The monofocal lens only corrects vision at one distance requiring the use of glasses to see 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.

This is where the third type of Intraocular Lenses comes into play: Extended Depth of Focus (EDF). These types of lenses can correct far, and intermediate distances vision, as well as astigmatism. The EDF technology brings more extension of focus for good near-distance vision. Also, the lenses do not create halos in the vision.

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.

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.
