LASIK Without Lasers? Researchers Could Have Discovered a New Method

New Method for Cornea Repair Without Lasers

Imagine if you could repair your eye damage without the need for lasers. Researchers might have found an innovative way to fix the cornea, using a method that’s less invasive than traditional LASIK surgery.

A team from Occidental College and the University of California, Irvine, developed a technique designed to temporarily soften the cornea. Their experiments involved rabbit eyes, and the results looked promising, preserving the corneal cells. While more studies are necessary to confirm the findings, the researchers believe this could be a viable alternative to LASIK.

“We have a long way to go before this technique makes it to clinics. However, if we succeed, it could be much cheaper, widely applicable, and perhaps even reversible,” shared Michael Hill, a chemistry professor at Occidental College, in a statement.

Why Some Avoid LASIK

LASIK is a common procedure for conditions like nearsightedness, farsightedness, and astigmatism. It reshapes the cornea—the clear outer layer that focuses light onto the retina—using a precision laser.

While generally effective, LASIK can weaken the cornea’s structure and lead to side effects like dry eyes and visual disruptions, with rare but serious complications arising for a small percentage of patients. The hope is that this new method could eliminate these risks.

A Potentially Safer Option

The proposed technique is referred to as electromechanical reshaping. Some researchers had previously applied it to modify collagen-rich areas in the body, such as ears. By adjusting the tissue’s pH through short electrical bursts, the cornea could be temporarily reshaped. Once the pH returns to normal, it hardens back into its original form.

In their lab, the researchers tested this technique with rabbit eyes, mimicking human myopia. They placed special platinum contact lenses over the eyes, acting as electrodes to guide the corneal reshaping.

After applying gentle electrical stimulation, the cornea became pliable and conformed to the lens’s shape. Impressively, the procedure didn’t damage any corneal cells or compromise the cornea’s stability. A video explaining their method is available online.

The findings, shared at the American Chemical Society’s fall conference, are still preliminary. The researchers recognize the need for more animal studies before moving on to human trials, with their next step involving live rabbits.

The potential applications of this research are promising, not just for myopia treatment but possibly for addressing farsightedness, astigmatism, and some types of cloudy vision as well.
