ISLAMABAD: Surgeons in Oxford have used a gene therapy technique to improve the vision of six patients who would otherwise have gone blind.

The operation involved inserting a gene into the eye, a treatment that revived light-detecting cells,BBC reported.

The doctors involved believe that the treatment could in time be used to treat common forms of blindness.

Prof Robert MacLaren, the surgeon who led the research, said he was "absolutely delighted" at the outcome.

"We really couldn't have asked for a better result," he said.
