Cure for presbyopia?
Reported by Susan Aldridge, PhD, medical journalist
You may be able to abandon your reading glasses, if new research comes to fruition.
One hundred per cent of people over 50 need reading glasses because of presbyopia - the inability to focus on near objects because of aging of the eye lens, which loses its flexibility. Treatment by laser surgery is thought risky, but researchers at the University of Michigan now suggest a new approach.
They are using a combination of microscopic bubbles and ultrasound to re-shape the eye lens. An ultrafast laser is used to create tiny gas bubbles within the lens and these are hit by high frequency ultrasound - this helps the surgeon to measure the pliability of the lens. The laser then re-shapes the lens in a very controlled way. It works in animals and it's hoped that it will be tested in humans in the not too distant future.

If presbyopia is defined as loss of corneal flexibility for near focusing for reading comfortably, then I have yet to discover any curative surgical procedure, quite simply because none of them improve flexibility.
The opening statement, "One hundred percent of people over 50 need reading glasses because of presbyopia" is inaccurate. I am over 50 and still do not need reading glasses.
That's true it's inaccurate,.and it's rare in the genetics that one should not need reading glasses or have any eye problems concerning presbyopia.
