Long work hours, insufficient nutrients in the diet
and lack of sleep are all contributing factors towards deterioration in
eyesight. Eye problems can also be hereditary in some cases. Spectacles
or contact lenses are the most common options for people suffering from
problematic vision. Some people choose to go for laser eye surgery or laser vision correction,
which is a type of Refractive surgery commonly known as LASIK. But this can be
quite an expensive procedure and can have some side effects such as corneal
infection and development of new visual problems. It is also not 100%
effective. But researchers at Shaare Zedek Medical Center and Bar-Ilan
University in Israel have come up with ‘Nanodrops’ a revolutionary new product
which can reportedly improve both nearsightedness and farsightedness.
‘Nanodrops’ is an eye drop which uses nanotechnology
to improve vision. ‘Nanodrops’ is now a patented product which was created by a
group of ophthalmologists at the research facility of the Shaare Zedek Medical
Center. David Smadja, one of the ophthalmologists who worked on the eye drops,
has said in his interview with the Jerusalem Post that
‘Nanodrops’ is “a new concept for correcting refractory problems.” The
researchers are claiming that ‘Nanodrops’ could not only be used for correction
of the corneas but could potentially replace multifocal lenses.
The product has been tested only on pig’s corneas and is being readied for human testing. The ongoing research work will determine the exact dosage of the eye drops that is required to repair the corneas and ultimately replace glasses or any kind of visual aid. Whether the solution is non-toxic and safe for human use is also something that will need to be determined before the product is marketed for commercial and medical use.
‘Nanodrops’, though far from being perfected as a replacement for visual aids, is still a promising development in the field of ophthalmology. If the team at Shaare Zedek Medical Center is successful in their venture, it could herald a new era for ophthalmologists and eye patients all over the world. We can only hope for a future where a person with visual difficulties can live freely without depending on any kind of visual aids.
