I have a question about the Light Adjustable Lens and extended depth-of-focus (EDOF). Definition: a single, contiguous, elongated focal point that enhances depth of focus. My concern, will glasses still work to sharpen my vision?
This is from Presbyopia Physician March 2023 article The Light Adjustable Lens: Reshaping the Premium IOL Landscape
The Monofocal IOL With a Twist
A misconception about the LAL is that it’s a simple monofocal lens aimed at precision distance vision. While this is partly true, it’s also highly oversimplified. It is indeed a monofocal lens; however, given its aspheric design, it does allow for an element of extended depth of focus (EDOF). This aids in extending visual range even in a plano targeted eye. Additionally, patients can elect to add negative spherical aberration to their nondominant eye during the light treatments. This adds an additional 0.50D-0.75D of EDOF, providing a solution for presbyopia and reducing the need for reading glasses.
Thank you
