A team of American researchers has developed a technique that allows reshaping the cornea and correcting vision problems, including nearsightedness and farsightedness, without the need for surgical incisions. This innovation highlights significant scientific progress, offering a safe alternative to traditional LASIK surgery.
EMR: A Non-Surgical Alternative to LASIK
According to the Saudi Press Agency (SPA), the technique, called Electromechanical Reshaping (EMR), works by modifying the pH levels in the corneal tissue using a precise electric current, allowing the tissue to be reshaped without surgery.
Researchers used special platinum contact lenses as molds for shaping the cornea. In experiments, a rabbit’s eye was fitted with the lens in a saline solution simulating natural tears. Within 60 seconds, the cornea conformed to the lens shape, achieving results similar to LASIK without any surgical incisions.
Potential Treatment for Corneal Opacity
Beyond correcting vision problems, scientists are exploring the potential of EMR to treat certain cases of corneal opacity, such as damage from chemical exposure, which currently requires a full corneal transplant.
The research team tested the method on 12 rabbit eyes, 10 of which were nearsighted. The results showed improved visual focus while maintaining the integrity of corneal cells.
Next Steps and Future Implications
Although this advancement could revolutionize eye surgery, especially for those wary of LASIK, the technique is still in experimental stages. No official approval date has been announced.
Future studies will involve a wider range of animals to determine the effectiveness and safety of EMR for various eye conditions. According to Michael Hill, a chemistry professor at Occidental College, the method could also be less expensive than traditional LASIK surgeries.
