Dysfunctional Lens Syndrome (DLS)
Losing the ability to focus on close objects, or accommodation, occurs in Stage 1 of DLS. We typically don’t notice this until after the age of 40, when decreasing lens elasticity causes tasks such as reading or working on a computer to become more difficult and more tiring. At this point, the proteins that make up the lens are still clear, but just become less flexible. At first, one can still focus by holding objects a little further away. Eventually, one relies on reading glasses for near tasks. The Kamra inlay can help Stage 1 eyes become less dependent on or even free of the need to use reading glasses.
In the second stage of DLS, the proteins in the lens become discolored and cause glare, mild visual blur, and decreased contrast sensitivity. A diagnostic test called the AcuTarget HD can measure the light scatter and decreased visual quality in your eye seen when the lens proteins begin to change. At this stage, visual function can be restored with a Dysfunctional Lens Replacement. During this procedure, the lens is replaced with a plastic intraocular lens implant (IOL). For more information on different IOLs, please visit our educational videos page and intraocular lenses page. While these lens implants are certainly not perfect, they can provide spectacular improvement in distance, intermediate, and near vision.
The final stage of DLS is the formation of a cataract. This occurs when the lens inside of the eye becomes yellow, cloudy, or even brown. The eye completely loses the ability to focus even with the proper glasses prescription, and glare can become an intensifying symptom. At this stage, cataract surgery is warranted.
