Passing a weak electric current through a contact lens made of platinum softened the cornea of a rabbit eyeball enough that its curvature shifted to match the lens in about one minute. Chemist Michael Hill of Occidental College and surgeon Brian Wong of the University of California, Irvine, reported the result, and it remains one of the more unusual candidates for replacing the laser in refractive eye surgery.

The account has been circulating for more than a year, and its dating needs care. The material was presented to the American Chemical Society’s fall meeting in August 2025, and a ScienceDaily page credited to the society carries a September 2026 date for what is the same story, with the same 12 rabbit eyeballs. Everything below therefore reads as an explainer of an early laboratory result, not as a fresh announcement.

Electromechanical reshaping and the platinum mold

The technique is called electromechanical reshaping, or EMR. Instead of cutting or vaporizing corneal tissue, as LASIK does, EMR places a platinum lens shaped to the desired corneal curve against the eye and applies a small electric potential. The American Chemical Society release as first posted on ScienceDaily describes the platinum lens acting as an electrode, with the current temporarily making the tissue pliable.

Hill put the contrast bluntly in the UC Irvine Beckman Laser Institute account: “LASIK is just a fancy way of doing traditional surgery. It’s still carving tissue, it’s just carving with a laser.” In EMR, nothing is removed. The cornea is held against the mold while the chemistry does the work, and when the current stops the tissue keeps its new shape. Because no tissue is removed, the researchers also point to possible reversibility and to simpler, less costly equipment than a surgical laser, though neither advantage has been tested in a living eye. Laser surgery, by contrast, permanently removes a measured layer of corneal tissue in every case.

Wong described how the idea arose. “The whole effect was discovered by accident,” he said, explaining that he had been looking at living tissues as moldable materials rather than as structures to be carved. His team had earlier shown the same principle on rabbit ears and on scar tissue in pigs, according to a second Beckman Laser Institute report, before turning to the eye.

The pH window that keeps the cornea clear

The current does not burn anything. It shifts the acidity of the collagen that gives the cornea its shape. Lower pH loosens the ionic bonds between collagen fibers, so the tissue can be pressed into a new curve, and when the pH returns toward normal the bonds re-form and lock that curve in place.

The difficulty is how little room there is. In an interview with The Scientist, Hill said collagen becomes malleable around pH 2 but turns opaque at pH 1.5, leaving “this tiny, narrow, little window” for reshaping. Delivering the current in intermittent bursts, rather than continuously, gives the acidity time to diffuse away through the tissue. Modeling was used to choose the burst frequency and duration.

Within that window the results were encouraging. Ten of the 12 rabbit eyeballs were treated to mimic nearsightedness, and in those the curvature moved to give the intended focusing power. Live Science’s report notes that the cells survived the treatment, which is the property that separates a reshaped cornea from a damaged one. The same work found the process took about a minute, roughly the duration of a LASIK procedure but without incisions.

Rabbit eyeballs, living tissue and a funding gap

The caveats are large. All 12 eyes were isolated rabbit eyeballs, not living animals and not people. Hill cautioned that a long road separates the laboratory result from the clinic. The team’s next steps are experiments in living rabbits, then tests of whether EMR can correct astigmatism and farsightedness as well as nearsightedness.

Durability is the question Hill raised most directly. A reshaped cornea that drifted back to its original curve within a couple of days would be of little practical use, Hill told The Scientist, and no one yet knows how long a reshaped living cornea would hold its form.

Funding is the other constraint. The work is supported by the National Eye Institute and the John Stauffer Charitable Trust, according to the September 2026 ScienceDaily page, yet Hill has said that uncertain funding is slowing the path toward human trials. A technique that needs only a mold and a modest electrical supply could in principle be cheaper than a laser suite, a point the researchers raise, but that remains a projection and not a measurement.

Corneal cloudiness from chemical injury often requires a transplant, and the researchers suggest EMR might one day treat it. The live-rabbit data from Hill and Wong will decide whether that moves beyond 12 isolated eyes.
