Research summary

 My research over the past forty years has ranged over a number of ocular problems but has concentrated on the inter-relationships between light and ageing, the mechanisms underlying age-related, diabetic and inherited retinal disease, and the development of lasers for use in ophthalmic diagnosis and surgery.  

This work has resulted in over four hundred research papers and numerous book chapters and books.  I invented and patented the revolutionary Excimer laser for the correction of refractive disorders with in excess of 35 million procedures now having been undertaken worldwide.   I also created the world’s first Diode laser for treating eye problems of diabetes, glaucoma and ageing.  I am editor and co-editor of numerous international journals.  I have been awarded the Nettleship Medal of the Ophthalmological Society of the United Kingdom, the Mackenzie Medal, the Raynor Medal, the Ridley Medal, the Ashton Medal, the Ida Mann Medal and the Lord Crook Gold Medal of the Worshipful Company of Spectacle Makers, the Doyne Medal of the Oxford Congress, the Barraquer Medal of the International Society of Cataract and Refractive Surgery, the Kelman Innovator Award of the American Society for Refractive and Cataract surgery, and the Lim Medal of the Singapore National Eye Centre.  I have been visiting professor at numerous universities on every continent.  In 2012 I received the Junius-Kuhnt award and Medal for my work on AMD.  Between 2011-2012 I was the Master of the Worshipful Company of Spectacle Makers. I was awarded the MBE in the 2013 New Year Honours List for services to Ophthalmology and an honorary DSc from Glasgow University in 2013 and delivered the Bowman Lecture and received the Bowman Medal in 2014.
