As our crystalline lenses age, they become less flexible, and by the time we reach around age 40 to 45, we find ourselves, as a natural occurrence, in need of assistance for near vision correction if our eyes have seen normally previously.
The easiest method for correction is with the use of glasses that are made specifically for near vision, or with a bifocal.
For some individuals that wish to avoid the glasses, there is the option of Conductive Keratoplasty. This procedure utilizes radiofrequency applications to the cornea to tighten the cornea and increase the ability to focus on near objects.
The procedure is relatively easy,, and recovery is swift. It may, however, need to be repeated after a few years, since the presbyopic process is progressive. However, it does have the potential of restoring the near vision lost in the presbyopia.
