Looks interesting (pun intended). Science is going places :)
Researchers are exploring a groundbreaking method to correct vision without cutting the eye, called electromechanical reshaping (EMR). Unlike traditional LASIK surgery, EMR temporarily alters the cornea’s chemistry so it becomes malleable. Using a platinum contact lens electrode, the cornea can be reshaped in about a minute, then “locks” into its new form as its chemistry returns to normal.
The technique works by adjusting pH levels in the cornea to loosen chemical bonds that maintain its rigid shape. Once softened, gentle pressure molds the cornea to the desired curvature. When the pH returns to normal, the tissue hardens in its corrected shape. Early experiments in rabbit corneas have successfully corrected nearsightedness and show promise for reversing certain corneal cloudiness.
While still in early stages, EMR could eventually provide a safer, faster, and possibly reversible alternative to LASIK. Researchers aim to expand testing to live animals and explore corrections for farsightedness, astigmatism, and other vision issues. If successful, this electric reshaping technique could transform eye care, making vision correction less invasive and more accessible worldwide.
