Susan Wright, 57, a charity consultant from Macclesfield, Cheshire, is one of the first people in the world to test the new implant.
She had surgery on both eyes six weeks ago and had her final follow-up appointment with ophthalmic surgeon, Brian Little, at the London Claremont Clinic last week.

Ms Wright suffered from cataracts and struggled to see objects up close which made driving virtually impossible and working at a computer increasingly difficult.
“I have never had particularly good eyesight,” said Ms Wright, “I had cataracts and long-sightedness and I would get a sense that there was a blank space in part of my vision.
“I stopped driving a while ago because I didn’t really feel comfortable with it, particularly finding my way anywhere if it was dark. I work with spreadsheets and it was getting difficult to tell the difference between the numbers ‘6’ and ‘8’ on a screen.
“Now my mid and long-range vision is absolutely excellent and I have been told my short range vision will continue to improve. Colours are much brighter and everything is sharper.
“I had planned to do a driving trip across the Pennines to see friends and I have achieved that now. And I can thread needles for the first time when I am sewing and read books and newspapers without reading glasses.”
The lenses are made of plastic and should never need to be replaced. Users have the added benefits that after cataracts are removed, they will never develop again.
Previous multi-focal lenses which can correct near and far vision have produced halo bursts and glare and there is a notable jump when switching rather than the smooth focus of a natural eye.

However the new implants have tiny circular grooves which change the way light is bent at various parts of the lens allowing for a seamless change when shifting focus.
The new lenses – called TECNIS Symfony Intraocular lenses - also allow more light to get through so that colours are more easy to distinguish.
There are almost two million people in the UK living with sight loss and the poor vision increases with age. 1 in 5 people aged 75 and 1 in 2 aged 90 and over are living have difficulty seeing.
Jenny Brindley, 58, a speech and language therapist, of Camberwell, South London, has also recently had the implants.
“Before the operation my eyesight had deteriorated a lot. Gradually things were becoming more and more yellow,” she said.
“I was quite short sighted and that had got worse and things were quite misty. I like art and visiting galleries and watching foreign films so my eyesight was stopping me doing a lot of the things I love.
“I wore prescription glasses since the age of seven, but I work with children with autism and they grab at them a lot.
“After the first operation it was the first time I could see the end of the bedroom clearly. I noticed for the first time that my husband’s jumper was purple. I had always thought it was brown. It’s really much better than I expected.”
Recent clinical trials of the implant showed that 81 per cent of participants reported 20/20 long-distance vision after surgery. 98 per cent said they never needed glasses for distance vision, 96 per cent for middle distance and 73 per cent for near distance.
The lenses cost around £3,900 per eye and are not yet funded by the NHS.
