Presbyopia is a natural condition. Beginning around age 40 to 45, the lens of the human eye looses its flexibility and thus its ability to change its shape and focus correctly on images at different distances. As a result, near objects are blurry.
Until recently, reading glasses were the primary option for people with presbyopia. Today, a few surgical procedures are available that may help some people to avoid reading glasses.
With Monovision LASIK, one eye is treated for distance vision and the other eye (usually non-dominant eye) is treated for near vision.
Laser Refractive Lens Surgery with Multifocal Lens Implants
Multifocal lenses are implanted into the eye replacing the normal lens. They provide relief for presbyopia at the same time as for nearsightedness or for farsightedness. Thus, the goal of multifocal lenses is to provide freedom from needing any eyeglasses or contact lenses.
