“Since 1990 I have dedicated my career, to researching and learning everything there is to know about pterygium. As an eye surgeon I was appalled at the fact 1 in 10 patients would need surgery again, and again. My blog and website are designed to inform you of the risks, realities and why a recurrence rate of 1 in 2000 should be the only standard you accept for your eyes.”
– Professor Lawrence Hirst

As well my decision to pursue an ethical and considerate medical practice resulted from a very sad episode in my early medical career.
