When we are fairly young (in our first
three or four decades of life), the natural lens of the eye can
adjust its focus, known as accommodation. This altering of focus
power is taken for granted as we look back and forth between near
and distant objects (e.g., reading and watching TV).
Regardless of what age a lens implant is used to replace the
natural lens of the eye, a normal monofocal lens implant will not
be able to adjust its focus. The Tetraflex lens implant is
referred to as an accommodating intraocular lens. This allows the
focusing power of the lens to change similar to our young natural
lens of the eye. The position of the lens changes slightly within
the eye as you focus at different distances.
The Tetraflex lens is best suited for people who are farsighted,
mildly nearsighted, or only require reading glasses before
surgery. Various measurements are taken to determine what lens
power is required for each eye. Once these measurements have been
performed, Boyd Vision will be able to inform you if the Tetraflex
lens is a good option for you.
If you choose the Tetraflex lens, it may take a little while for
the near vision to become clear. There is a muscle inside the eye
that helps the natural lens of the eye to change its focus. As we
get older, this muscle does not see much action as the natural
lens becomes more rigid. As a result, it takes some ‘exercising’
to tone up the muscle again. Focusing exercises include simple
tasks such as reading newspapers, doing crossword puzzles, or
working on the computer. At first, your eyes may tire easily. Over
a few weeks, focusing becomes easier and easier. |
