The pin-up, who has just turned 20, has become one of the youngest people in Britain to have the procedure done.
The ten-minute op means the model has gone from being unable to see the clock by her bed to reading even the smallest print without glasses.
Rhian says: “I could hardly see anything before but now I’ve got near-perfect vision.
“The first thing I saw next morning was the clock in my room. I couldn’t even read the time on it before. Then I lay there reading tiny words and letters on posters on my wall.
“I was so delighted, I rang all my friends and family to tell them I could see again.”
Laser eye surgery has never been more popular in the UK. More than 300,000 people have had the treatment since it first emerged in the early Nineties.
The number of annual procedures is rising steadily as surgery becomes more freely available.
Actor Ewan McGregor and golf ace Tiger Woods have both had their eyes lasered.
Rhian began wearing glasses at the age of 14 after tests revealed her vision was failing.
She recalls: “I couldn’t see the board at school. And although I didn’t need glasses all the time, my eyesight got bad quite quickly.
“Every time I went back to the optician I needed a stronger prescription.”
The model, who lives with mum Anita, 52, and dad Steve, 49, in Radcliffe, Greater Manchester, had heard of laser surgery but was terrified by the idea of anyone touching her eyes.
In fact, she was so scared she FAINTED when staff at Optical Express in Manchester put drops in her eye during tests to see if she was suitable for surgery.
But she still decided to go through with it.
Doctors gave her the sedative diazepam to calm her nerves before the op itself. She says: “I felt like I was a bit drunk. But I was still scared. Afterwards, my eyes were really streaming.
“It felt like I had peeled more than 100 onions.”
Despite everything she had to go through, the next morning her vision was perfect.
