A 109-year-old woman has proved that age is no obstacle when it comes to correcting vision, after becoming the oldest woman in the world to undergo treatment for cataracts.
Chinese woman Guo Liansheng, who was born in 1903, is set to enter the Guinness Book of World Records after she underwent a procedure known as intraocular lens (IOL) surgery.
The patient has been unable to see anything except minor changes in light for the best part of a decade and was deemed too old to have laser eye surgery.
However, she was referred to eye specialist Dr Chu Tao, a cataract expert at Shanghai New Vision Ophthalmic Hospital, who suggested IOL treatment.
Dr Chu Tao used C-Flex 570C lenses to carry out the procedures on each eye, which were conducted almost a year apart.
The hospital, which covered all of Ms Liansheng's costs, reported that there were excellent final refractive results, and she was able to see clearly once again.
According to the patient, the best thing about having the surgery done was that she was finally able to see her great-great-granddaughter.
Rayner, the company that developed the lens, noted that it is the latest in a long line of successes that, with the help of worldwide charity organisations, has benefitted thousands of people.
Donald Munro, chief executive of Rayner, said IOL lenses improve the lives of people all over the world but it is "especially gratifying" in a case like this.
He explained: "The technology is so advanced now, and the procedure so simple, that almost anyone can benefit from vastly improved eyesight. It's also proof that age is no barrier to health aspirations."
Rayner became the first and only IOL manufacturer to receive the Queen's Award for Enterprise in International Trade in 2009 and has been helping to provide visual clarity to patients across the world for over 60 years.
