Presbyopia
Presbyopia describes the condition where the eye exhibits a progressively diminished ability to focus on near objects with age.
Presbyopia's exact mechanisms are not known with certainty, however, the research evidence most strongly supports a loss of elasticity of the crystalline lens,
Although changes in the lens's curvature from continual growth and loss of power of the ciliary muscles (the muscles that bend and straighten the lens) have also been postulated as its cause.
Normal and Presbyopic Vision
New Laser Treatment
A special kind of laser is used for
cutting, a femtosecond laser (fs-
laser), which is not only
extremely precise, but which
also makes very fine cut
grooves. Since the size and
position of the lens differ from
patient to patient, control and
monitoring of the cutting is done
via optical coherence
tomography (OCT). The grooves
form gliding planes in the tissue
of the lens and can restore
elasticity.

Cataract
In the United States, age-related lenticular changes
have been reported in 42% of those between the ages of
52 to 64, 60% of those between the ages 65 and 74, and
91% of those between the ages of 75 and 85
