Visible Wavelength Laser for Corrective Eye Surgeries – Easier and Cheaper

A group of researchers led by Prof. Zeev Zalevsky from the Alexander Kofkin Faculty of Engineering at Bar Ilan University are the first to show clinical evidence following the use of a visible wavelength laser for laser eye surgery. Currently, visible wavelength lasers are not used in clinical practice due to their absorption by the cornea (therefore not interacting with corneal layers). In order to overcome this issue, the researchers combined a visible wavelength laser with an organic substance, approved by the FDA called fluorescein, in order to cut the cornea. Unlike the laser techniques currently used, the use of visible wavelength lasers will make it easier for surgeons to perform operations, while also significantly reducing the price of surgeries due to lower production and maintenance costs.
