EMR Corrects Nearsightedness Without Lasers

SkimNews Take
The temporary nature of EMR's corneal reshaping, requiring contact lenses for the procedure, suggests it could offer a non-surgical equivalent to prescription glasses or contacts, rather than a permanent replacement like LASIK.

- Michael Hill of Occidental College criticizes LASIK as still being tissue-removal surgery, just performed with lasers, motivating the search for non-invasive alternatives.
- Brian Wong at UC Irvine discovered the EMR effect accidentally while studying collagen-rich tissues, finding that electric current can shift pH and temporarily soften corneal structure.
- Electromechanical reshaping (EMR) successfully corrected nearsightedness in rabbit eyes within approximately one minute during early tests, maintaining corneal integrity without incisions or lasers.
Why it matters: If EMR proves safe and effective in humans, millions with refractive vision problems could avoid the risks and costs of LASIK. Patients gain access to a potentially reversible, non-surgical option, while eye surgery clinics and laser equipment makers may face disruption if demand shifts.
