Israeli scientists have unveiled a novel vision correction technology that could potentially free individuals from spectacles, contact lenses, and surgical procedures. This involves specialized eye drops based on nanotechnology, capable of altering the refractive properties of the cornea.
The advancement is being pursued by a team of specialists from the Shaare Zedek medical center and the Institute of Nanotechnology and Advanced Materials at Bar-Ilan University. The method’s foundation is a multi-step, yet non-invasive, process. Initially, a dedicated smartphone application gauges the individual visual parameters. Subsequently, a low-power laser applies a microscopic optical pattern onto the corneal surface. Following this, the drops themselves, containing synthetic protein nanoparticles, come into play, activating this pattern and adjusting light refraction.
According to the creators, this approach fundamentally differs from established techniques.
“We aimed to devise a remedy that bypasses surgery and can be tailored to the specific patient,” note the project participants.
Preclinical trials were conducted on animals. In experiments involving pigs, the scientists managed to achieve considerable vision improvement for both nearsightedness and farsightedness. The outcomes demonstrated that the nanodrops can modify the eye’s optical characteristics without causing tissue damage.
The technology holds particular appeal for people experiencing age-related farsightedness, as well as patients for whom only surgical correction was previously indicated. The new approach potentially lessens dangers, shortens the recovery time, and might be utilized outside of a hospital setting.
Researchers emphasize that, despite the encouraging findings, the technology requires further verification. Clinical trials involving humans are necessary to confirm long-term efficacy and safety.
Nevertheless, experts regard the development as a significant stride for ophthalmology. Employing nanotechnology for precise and gentle vision correction could render treatment more accessible and noticeably ease the lives of millions globally.
