Blindness Treatment - Artificial Cornea Has Cured 10 years Old Blindness - News -

Blindness is obviously a very dangerous condition which puts the patient's life in immense darkness. Any abnormality in the structure of the eye can lead to blindness. For example, Any abnormality in the following structures can lead to blindness.

  • Cornea
  • Pupil
  • Aqueous Humor
  • Vitreous Humor
  • Lens
  • Intraocular pressure
  • Retina 
  • Optic nerve.
Therefore, the localization of abnormality is necessary for proper treatment. The identification of the false structure and appropriate treatment is the goal of the therapy.

A man who's been blind for ten years and had given up hope of ever seeing again has received the gift of sight this Christmas. A new artificial cornea has allowed him to see.

Norman Simpson badly damaged the front of his one good eye in an accident.

Corneal transplants from donor's eyes failed and doctors said there was nothing more they could do.

But the artificial cornea - the window at the front of the eye - has improved his vision so much he can read newspapers and see his wife again.

"The first person I saw was Carmel. She came up to me and I could see her smiling face. That was lovely," he said. "I haven't seen her properly for 10 years.

"After the accident, we were going in a taxi to the hospital and I kept stroking her face and saying 'that's the last time I ever see it'. So this is just great."

The new device, called a kerato-prosthesis, consists of a plastic lens which slips through a stabilising ring.

Sandwiched between the two is a doughnut of donated eye tissue, which is stitched to the patient's eyeball to hold the device in place.

The operation takes two hours and can be done under local anaesthetic.

Sheraz Daya, medical director at the Centre for Sight in Sussex, said the technique could help around 5,000 patients who suffer from corneal blindness.
