3rd September 2025 – (Los Angeles) A groundbreaking technique, Electromechanical Reshaping (EMR), is poised to revolutionise ophthalmology practices by potentially replacing laser surgeries in the future at a fraction of the cost. Unlike Laser-Assisted in Situ Keratomileusis (LASIK), which is currently the gold standard for vision correction, EMR provides a gentler method for correcting corneal issues such as nearsightedness, farsightedness, and astigmatism.
The cornea’s misalignments, whether too steep, flat, or uneven, contribute to various visual impairments. Traditionally, laser procedures like LASIK sculpt the cornea by removing small tissue portions. While effective, LASIK poses risks as it permanently weakens the cornea, increasing the likelihood of future vision complications.
Non-surgical alternatives like specialised contact lenses offer temporary corneal moulding but demand nightly wear and may lead to infections. Scientists and medical professionals are now exploring ways to reshape collagen-rich tissues like the cornea permanently, without invasive methods.
Dr. Brian Wong, a surgeon-engineer at the University of California, Irvine, discovered a potential solution a decade ago during his work with thermal techniques for reshaping tissues, including the cornea. A serendipitous incident involving electrolysis sparked a new approach, leading to the development of EMR.
EMR utilises small electrical pulses to split water on the corneal surface, releasing protons that alter the corneal tissue’s mechanical properties. By disrupting collagen fibers’ bonds and changing the tissue’s pH, the cornea becomes malleable. A custom metal contact lens-like mould shapes the cornea, which retains the new form as the electric pulses cease and natural physiological processes restore the cornea’s pH balance.
Recent tests presented by Wong and Dr. Michael Hill at the American Chemical Society’s conference showcased EMR’s potential. Their proof-of-concept study demonstrated successful reshaping of rabbit corneas without compromising transparency, affirming the technique’s safety and feasibility.
EMR procedures are expected to be more cost-effective compared to LASIK, as they do not rely on expensive laser platforms. This affordability could make the technique accessible to clinics and regions previously excluded from LASIK services.
While EMR requires further testing for safety and longevity, progress is being made towards in-vivo animal trials to ensure lasting results. Hill emphasises the importance of continued funding for basic research to advance transformative technologies like EMR, underscoring the unpredictable yet game-changing outcomes that stem from curiosity-driven scientific exploration.
