Cure for reading glasses may be in view

ANN ARBOR, Mich.---It's 10 p.m., and you've finally relaxed into your favorite comfy chair to browse the day's newspaper. Patting your shirt pockets you realize there's a problem, and now you're not relaxed anymore. You can't find your reading glasses. Again!

Presbyopia---the inability to focus on close objects resulting in blurred vision---affects 100 percent of people by age 50. Historically, laser correction of the intraocular lens for presbyopia has been proposed, but it is risky because there is no way to monitor the procedure---no way for ophthalmologists to see what they are doing to the lens being cut.

But a tool developed at the University of Michigan allows for a potentially noninvasive, painless fix to presbyopia using tiny bubbles that help ophthalmologists reshape the eye's lens and restore its flexibility and focusing ability. Matthew O'Donnell, professor and chair of the U-M Department of Biomedical Research, along with Kyle Hollman, assistant research scientist and adjunct lecturer, and graduate student Todd Erpelding, developed the method. Recently, it was successful when tested in pig lenses.

Presbyopia usually starts around age 40, O'Donnell says. The predominant belief is that fibers created in the intraocular lens accumulate and stiffen, thus making the lens less flexible. Without that flexibility, the lens can't change shape to focus on near objects, a process called accommodation.

So, while a young eye is like an automatic focus camera, the presbyopic eye can be thought of as a fixed focus camera, he says. One way to potentially solve presbyopia is to laser away some fibers to restore flexibility, but there is no way to know how much or where to cut, he adds.

"There are no noninvasive or minimally invasive procedures for presbyopia," said O'Donnell, 55, who explained that he started research on presbyopia when he began to notice his own near-sight failing. He held up his reading glasses: "I got sick
