Biomedical scientists have created a non-invasive vision correction procedure that molds living corneas in about one minute using custom platinum contact lenses and low-voltage electricity, providing a potential scalpel-free alternative to LASIK surgery.
Developed by researchers from Occidental College and the University of California, Irvine, the technique is known as electromechanical reshaping. Unlike conventional laser-assisted procedures that permanently cut away corneal tissue to adjust focus, this novel strategy relies on subtle electrochemical adjustments rather than physical excision. During the procedure, a shaped platinum contact lens acting as an electrode is positioned against the surface of the eye.
When a mild electrical current passes through the ocular tissue, it induces a localized, controlled drop in pH. This temporary acidification weakens ionic bonds within the collagen protein matrix, causing the cornea to soften and behave like a pliable material. The tissue then conforms to the exact shape prescribed by the platinum lens mold within sixty seconds.
Once the current is switched off and physiological conditions normalize, the collagen framework stiffens again, holding the cornea in its newly corrected curvature. In laboratory tests conducted on donor rabbit eyes, investigators successfully remedied nearsighted refractive errors while maintaining high rates of cell survival. Early findings also suggest that the approach could potentially reverse corneal cloudiness caused by chemical trauma without requiring a transplant.
Although living animal studies and subsequent human clinical trials remain necessary, researchers hope the device will eventually provide an accessible, low-cost option for refractive eye therapy.
