Presbyopia Correcting Lens Simulator

Multifocal and extended depth of focus lenses will very likely improve your depth of field and decrease your dependence on reading glasses.  You may also experience side effects including loss of contrast, glare, and halos.    

 

Understanding your personality, physique, pathology and predispositions (the 4 P's) may help you decide whether you want to opt for these lenses.

The pictures below approximate the difference between standard intraocular lenses and multifocal or extended depth of focus lenses.    Your actual experience is affected by lighting, pupil size, and the task at hand.  

Note:  Your cataract may make simulations more difficult to appreciate.  Consider going over these simulations with a friend who has already benefited from cataract surgery, or someone who is younger and does not have cataracts.

Improved near vision

Improved near vision, the primary effect of presbyopia correcting specialty lenses, is seen below.

Standard Intraocular Lens

Reading glasses are usually necessary

Extended Depth of Field/Multifocal Lens

Reading glasses are often not necessary

Reduced Contrast

 

One side effect of multifocal and extended depth of focus lenses is reduced contrast. This evident in the pictures above, is simulated again below:

Standard Intraocular Lens- Normal Contrast

MF/EDOF Lens- Reduced Contrast

Halos

Multifocal and Extended Depth of Focus lenses cause varying degrees of halo surrounding images.  This is more evident at night surrounding streetlights and headlights.

Glare

Glare and starbursting can also occur with presbyopia correcting lenses.

Summary

When you choose presbyopia correcting lenses, it is likely that you will experience a balance of desirable effects and undesirable side effects.   Who you are may decide how happy you are with presbyopia correction.   Learn about the Four P's- personality, physique, pathology, and predispositions- that may help predict how happy you would be with presbyopia correcting lenses.
