加州大学欧文分校研究团队正在开发一种名为电机械重塑(EMR)的视力矫正新技术，有望提供比LASIK更安全、更经济的替代方案1。该方法采用小电位和特殊形状的铂金镜片暂时软化角膜，使其可在约一分钟内被重塑，无需使用激光或进行切口1。
早期实验在12只兔眼球上进行，其中10只被处理为近视状态，全部成功改变了角膜曲率以达到预期焦点1。研究人员通过精确控制pH梯度实现角膜重塑，同时保持了细胞存活1。整个矫正过程的耗时与LASIK激光部分相当，但避免了创伤性切口带来的风险1。
该研究目前仍处于早期阶段，研究团队的下一步计划是在活体兔子上进行动物实验1。这项工作由美国国立卫生研究院眼科研究所和约翰·斯塔弗慈善信托基金提供资助1。
Researchers at the University of California, Irvine have developed a novel vision correction technique called electromechanical reshaping (EMR) that requires neither lasers nor surgical incisions.1 The method uses small electrical potentials and specially shaped platinum lenses to temporarily soften the cornea, allowing it to be reshaped in approximately one minute.1
Early laboratory experiments conducted on tissue from twelve rabbit eyes demonstrated the technology's potential.1 Of these, ten eyes were treated to simulate myopia, and all successfully underwent corneal curvature changes to achieve the intended focal point.1 The researchers maintained cell viability throughout the process by precisely controlling pH gradients during corneal reshaping.1 Unlike LASIK, which requires incisions, the EMR approach accomplishes correction without cutting the cornea, positioning it as a potentially safer and less expensive alternative.1
The research remains in its preliminary stages, with the next phase involving live animal trials in rabbits.1 The work has been supported by the National Institutes of Health's National Eye Institute and the John Stauffer Charitable Trust.1
