Laser-free vision correction uses electrical current to reshape eye

Imagine correcting your vision in under a minute – no lasers, blades or pain. Scientists have developed a novel, non-invasive technique that reshapes the cornea using only a mild electric current and a temporary pH shift. In early trials, it reversed myopia without the need for traditional surgery – and could be the most radical advancement in eyesight correction technology since LASIK.

This emerging method that can remodel the cornea through mild electric potential, known as electromechanical reshaping (EMR), was detailed by researchers from Occidental College and the University of California, Irvine, during the American Chemical Society’s Fall 2025 meeting this week.

The cornea is the clear, dome-shaped surface at the front of the eye, acting as a transparent window that helps focus incoming light. It's made of tightly packed collagen fibers and is designed to be strong and smooth. When light enters the eye, the cornea is the first lens it hits – and it's here that most of light-bending (refraction) occurs in order to focus the light onto the retina at the rear of the eye. However, if the cornea has an irregular curve, it results in conditions such as nearsightedness (myopia) and farsightedness (hyperopia).

If it does what the article says it does, it would seem to be almost without risk.

I already tried this. I clamped jumper-cables on my eyeballs and cranked the car engine.

All that happened was my eyes watered pretty good.

Unfortunately I’m going farsighted.

If the cornea can be shaped one way, there must be a way to shape it the other way. If this does go mainstream, they will probably be able to do farsightedness as well.

If the cornea can be shaped one way, there must be a way to shape it the other way. If this does go mainstream, they will probably be able to do farsightedness as well.

From Grok:

Electromechanical reshaping (EMR) is an emerging, non-invasive technique that uses mild electrical currents applied via a specialized contact lens-like electrode to temporarily soften the cornea through electrochemical changes (such as pH shifts from water electrolysis). This makes the tissue malleable, allowing it to be reshaped with a mold to alter its curvature before it re-hardens, restoring optical transparency with minimal damage to cells or collagen structure.

Yes, EMR can be used to correct farsightedness (hyperopia). By employing a steeper mold during the reshaping process, it increases the cornea’s curvature to enhance focusing power for near vision, addressing the flatter corneal shape typically associated with hyperopia. This capability extends to a range of refractive errors, including myopia (nearsightedness) and astigmatism, with ex vivo studies on rabbit eyes demonstrating controlled curvature changes over various refractive powers while preserving tissue viability. However, as of recent developments, EMR remains experimental—primarily tested for flattening the cornea to treat myopia in animal models—and human clinical applications are still in planning stages, with ongoing research to fully validate corrections for hyperopia.

“If it does what the article says it does ...”

If it does work expect heavy resistance from Big Optical. Just like Big Dentistry quashes any research that leads to a cure for periodontal disease and such. A cure would put a lot of dental folks out of work.

I can sort of relate to him.

My eyes are somewhat inherently lazy. I don’t have really very much in terms of eye muscles.

No fix for that. I’ve been to enough specialists.

I did get lasik in the early 00s. Some of the best money I’ve ever spent. No regrets.

It was like going from so so analog color TV to HD.

How is platinum printed to form the mold?

The eyeball if I remember changes it’s shape as we age, so depending on the newer developing mechanical stresses on the cornea, will the EMR reshaped tissue be more vulnerable to those stresses?
Also, other questions arise. What other parts of the eye are effected by the EMR energy? Does it effect blood vessels in the eye? Help detach retinal tissue? Jumble up the rods and cones? Effect the optic nerve? Loosen up the ocular muscles?

After wearing contact lenses since a teen, now requiring cheaters to read and work on the computer, a new doctor finally (without telling me) fitted one contact for distance, and another for mid-vision/reading in my lazy right eye for the computer/reading. He told me to blink, blink, blink and read the tiny print.
<pHow can I read this tiny print? Then he told me. It was amazing. Life changing. All those years of fumbling for reading glasses—gone.

The early versions of LASIK underestimated the eye’s ability to heal itself...thus returning vision to something resembling the original vision.

However, because you’ve shaved mass from the cornea, it permanently doesn’t heal. Cops are forbidden to have Lasik for this reason, because a blow to the head has a greater chance of leading to blindness and this risk is permanent.

This surgery, because it only reshapes it, doesn’t damage the eye permanently. At least from the article. It seems safer to me than lasik.

All great questions. I have a branch occlusion-a tiny blood clot-in a blood vessel
feeding the retina in my right eye. It’s like looking through a thin film. I also have glaucoma as well. I would be very hesitant about such a procedure without knowing what effects it might have.

LASICS. I’ve had both Caratact and Lasix to fix the screwed up Catract, you live on dry dye drops for the rest of your life. And they are no longer cheap—$20 for a small bottle.

Skip it.
