The process of removing hard, dense cataracts is no longer difficult, one expert has claimed.
Eye surgeon Dr JS Titiyal told the Times of India that phacoemulsification has helped to radically alter the way in which cataracts are removed - something demonstrated in procedures he himself has conducted on famous patients including Indian prime minister Manmohan Singh and president Pratibha Patil.
He explained: "There is more effective phacoemulsification, better fluidicas, excellent followability and increased safety in the technique."
Dr Titiyal added that further developments in phaco will only help to simplify the process further and help to improve the visions of hundreds of thousands of people worldwide.
Meanwhile, a new study into the process of how people perceive light of varying brightness may eventually lead to new therapies for those with advanced retinal disease or even blindness, experts at the University of Manchester have claimed.
