Bausch + Lomb, a global manufacturer of contact lenses and related products, has launched enVista™, its new, glistening-free, hydrophobic intraocular lens (or IOL). The company announced this fact during the 2011 Congress of European Society of Cataract and Refractive Surgeons (ESCRS) in Vienna, Austria.
enVista lenses, which are Bausch+Lomb’s first hydrophobic IOLs, constitute an important step forward in the technology of intraocular lens manufacture. The new lenses differ from other IOLs in that they combine aspheric, aberration-free optics with a glistening-free material, providing improved vision quality. Moreover, enVista lenses minimise posterior capsular opacification, which consists in patient vision becoming clouded after surgery.
According to Professor David Spalton from St. Thomas Hospital, London, the new lens offers increased visual acuity, because it has been clinically demonstrated to be glistening-free. Glistenings, often occurring in hydrophobic acrylic intraocular lenses, are microvacuoles filled with fluid that can appear within an IOL, negatively affecting the quality of vision.
The new lens has received CE Mark approval in the EU.
