New procedure to help save eyesight of patients

Patients in Somerset with a "debilitating" condition that causes blurred vision can now access treatment that prevents progression of the condition.
Keratoconus, which causes the cornea to thin, normally develops during teenage years or early adulthood and tends to gradually worsen over time.
A new procedure has been introduced at Taunton's Musgrove Park Hospital in Somerset to treat patients – called corneal cross-linking.
Kevin Slade, 48, from Taunton, has had the procedure in his left eye and said it had made his vision "so much better".

Keratoconus is a type of corneal ectasia, where the round clear window of a patient's eye becomes progressively thin, causing it to become cone shaped and irregular.
The speed and severity of change in vision is most common in people with connective tissue diseases, allergic eye disease, conditions such as Down's Syndrome, and children with learning difficulties or autism.
Mr Slade said he was relieved to have his left eye operated on December.
The 48-year-old has learning disabilities and was anxious about having to travel to London for the procedure.
He was on the verge of losing his driving license because of blurred vision but is now able to carry on living and normal life as his condition has been stabilised.
Mr Slade said: "It was quite a big impact on driving for me before but having the operation has made it so much better and that amazing surgery was very very quick, and no pain at all."

The cross-linking procedure helps fix it by removing the surface layer of the cornea (the epithelium) and then placing riboflavin drops onto the eye which are excited by using UV light and then form free radicals.
Those free radicals lead to covalent bonds forming within the cornea making it stronger.
It is the only treatment available that stops keratoconus from getting worse, and has a 95% success rate, with only 5% of patients going on to need further treatment, according to NHS figures.
Patients with keratoconus will no longer need a lifetime supply of contact lenses, which tended to cost the NHS £600 per patient, per year, over their lifetime.

Ruta Balakit, from Bridgwater has also recently had the procedure after discovering she had a problem with her vison a year ago.
The 38-year-old said: "My eyes were quite itchy mostly in the evenings.
"Even sometimes it would wake me up. I started to think what's wrong?"
After a check up at Specsavers, Ms Balakit was referred to hospital.
"I am happy its hear I don't need to go far away for treatment - that is really good," she said.
Somerset NHS Foundation Trust is the only trust in the South West area to offer the procedure.

Mr Indy Sian, consultant ophthalmologist at Musgrove Park Hospital, said: "Historically, our patients have needed to be seen at a specialist clinic in London to have this treatment, which was understandably very difficult for young families, or those individuals with additional needs.
"Patients with a learning disability or Down's Syndrome may struggle to understand the whole process, so being able to have their treatment in a more familiar setting will be to their advantage.
"It will also make subsequent follow-up care much easier."
He added the condition can have a "debilitating effect" on peoples lives, as it can impact schooling, lead to other injuries through falls and can lead to needing a corneal transplant.
"Being able to offer this cross-linking procedure here in Somerset means we have an effective way of stabilising a patient's sight, so it does not get any worse over the years, and it can even improve the sight in some cases," Mr Sian added.
