An Optometrist and an Ophthalmologist discuss - sometimes over a pint of Guinness - how these two previously fractious disciplines have been brought closer together. From different sides of the Irish border, John Ferris and Dermot Keogh know a thing or two about overcoming division. Their guests bring extensive experience and expertise from across the two sectors: they share their passion for all things optical, discuss how the fields of Optometry and Ophthalmology can learn from each other, and the medical developments that are just over the horizon.
