New Eye Gel Treatment to Improve Aging Eyesight

LONDON (Reuters) - Millions of aging baby-boomers could be spared the need to use reading glasses to see the small print if a new treatment developed by scientists in Australia is proven safe and effective. The technique, which involves replacing the contents of the lens in the eye with a soft polymer gel, will initially be used to improve cataract surgery in elderly patients.

"But once it is shown to be safe and effective, we think that more and more younger people who are starting to need reading glasses will adopt it as well," Arthur Ho, of the University of New South Wales, told New Scientist magazine on Wednesday.

As people age, the lens in the eye, which focuses by changing shape, becomes less flexible so by the time most people reach their mid-to-late 40s they need reading glasses.

Ho, who is a member of the Australian government's multinational Vision Co-operative Research Center, believes he and his team have discovered the right gel formulation for human eyes and hope to begin trials next year.

Tests on animals have been promising.

Inserting the gel would be similar to cataract surgery but the lens would not be replaced. The contents will be sucked out by a tiny incision in the cornea and replaced with the gel.

"This could be a quick 15-minute procedure," Ho added.

And Jiffy-Lube will replace the oil every 50,000 miles.

Just reverse the >< in that command line.

Will it be like breast implants where stuff starts shifting around? Will the stuff leak out?

I was one of the earliest patients for laser corrective surgery for nearsightedness in the US, but I don't have much confidence in the efficacy of a yet-unproven technique that permanently removes the lens if there is nothing actually wrong with it.

Here's an idea. How about a procedure that reverses the age-related stiffening of the existing lens?

Or the lenses contents, as the case may be.

Presbyopia is multifactorial.

It's just not the changes in the lens but also the weakening of the muscles and fibers involved in changing it's shape.

I don't see how this prodedure could correct it, but I wish them luck.

Could eyes exercises improve your vision?

Old animals can read better?

Maybe eye exercises in tandem with the goop.

It is a simple idea, really. Just find some clear goo that has the same index of refraction as natural eye goo and isn't toxic. Voila!

That's what I thought immediately. (Too bad we'd have to actually think up a way to accomplish it in order to get the patent!)

Not according to the American Academy of Ophthalmology and it's been studied.

It's just part of aging and, well at least aging beats the alternative :->

OK, as someone who's had three (3) corneal transplant operations, the most recent May of this year, I simply quote Monty Pyton

"The contents will be sucked out by a tiny incision..."

Now that makes me cringe. < shudder>

It's ... also the weakening of the muscles and fibers involved in changing it's shape.

I thought Viagra would fix that.

LOL! We'll have to ask Bob Dole if he's thrown our his reading glasses.

They should be able to treat more than just presbyopia. By fiddling with the index of refraction, they should also be able to change the focal length of the lens; in effect, adding or subtracting diopters from the eye without glasses. They just need to be careful about dispersion so as not to mess up the eye's color correction.
