The 90-year-old, who plays Dot Cotton in the soap, volunteered to undergo the surgery as part of a trial.
A thrilled June said: “I can see people’s faces and recognise my children again. I can read again.”
The procedure, which treats the leading cause of blindness, will be rolled out across the country later this month.
I can see people’s faces and recognise my children again
Trials have shown a dramatic improvement in the sight of patients with intermediate to advanced macular degeneration, affecting up to five million Britons, most of whom have no other treatment available.
June, the second longest-serving character in soap, plays chain-smoking launderette assistant Dot, one of EastEnders best-loved characters.
She was one of the first patients to undergo the Eyemax Mono technique with “astonishing” results.

Twice-married Ms Brown, a mother of five, from Surrey, who lost her first husband to suicide and her second to dementia in 2003, was diagnosed a decade ago and had developed an advanced stage of the disease.
Her condition which was written into her on-screen tragicomic character last year left her unable to drive and barely able to read.
She was also struggling to learn the lines of her scripts which were printed in very large type for her.
Speaking after the operation June said: “I can see people’s faces and recognise my children again.

“I can now distinguish colours and the pattern on a rug that I couldn’t see before. I can read again and I don’t think I would be able to see at all if I hadn’t had the operation.
The star was diagnosed with macular degeneration
“It is slowly improving all the time. I think my brain is teaching my peripheral vision to come into operation."
June’s eye surgeon Bobby Qureshi, who pioneered the new technology at the London Eye Hospital, said he was amazed by the success of the operation.
He said: “When I tested her eyes after the operation, I nearly fell off my chair. The improvement was astonishing.”
“This is so exciting. Up to 20 million patients worldwide could benefit. It can give back life to people who could no longer do normal everyday things.
June’s daughter Sophie Johns, a 56-year-old former zookeeper, said: “The loss of vision got mum down. She felt life was completely closing in on her and she felt isolated.”
Ms Johns had a lens implant last year to treat age-related sight loss. She was astonished by the outcome.

She said: “By the time I had the operation my vision was very fuzzy and I couldn’t see people’s faces very well nor read at all without glasses. Life was closing in. When I took off the eye patches after the operation the colours and brightness were astonishing. Within a couple of days I could read my phone again. It was spring and the bluebells looked deep purple rather than sludgy blue.
”This technology means we can help maintain people’s vision for as long as possible and in most cases improve it.”
The lens surgery helps readjust the nerve signals in the brain to access the remaining healthy parts of retina.
The Eyemax Mono technology will be introduced to UK surgeons at the Royal College of Ophthalmologists annual meeting in Liverpool next month.
More than 5,000 surgeons from around the world have already asked for the technology. The procedure, which can take up to five minutes but which was achieved in just 60 seconds with June, will be made available to eye surgeons across the UK and 25 countries in Europe next week following trials in five European countries which showed 96 per cent of 300 patients involved saw improvements in vision.

On average those fitted with the lens could read four lines below their previous level on the eye chart improving both distance and near vision. No patient lost vision.
Results from a separate trial of 100 patients were presented at the European Society of Cataract and Refractive Surgery last year and further trials from 500 patients across five countries are awaiting publication in leading journals.
It is hoped that UK health watchdog, the National Institute for Health and Care Excellence can then consider the technology to make it available on the NHS.
Fifteen per cent of people between 60 and 70 have age related macular degeneration and this increases to half of those aged over 85.
This includes hundreds of thousands with an advanced form of the disease and millions with the intermediate form.
June's scripts had to be printed in large letters
Dr Qureshi said: “We are just trying to help these patients slowly losing their vision who have been told for a generation that nothing can be done. This is not a cure but we could treat most patients with this disease and improve their sight.”
A lens is inserted into an incision of less than 2.2mm and redirects focused light from damaged parts of the retina to healthier areas extending the area of usable macula.
Dr Qureshi’s team were inspired by the same Nasa technology that fixed the Hubble space telescope to create a lens redirecting light in one direction.
The first version consisted of two lenses but the technology has now evolved allowing light to be diverted in three dimensions.
