Professor Graham Barrett, the innovator behind RayOne EMV in partnership with Rayner, joins Mr Alastair Stuart, Medical Director of Optegra UK, in his clinic to discuss why he frequently chooses RayOne EMV for his patients. Mr Stuart shares both his clinical expertise - covering patient selection, calculations, and outcomes - and his personal experience of recommending the lens for his own father’s cataract surgery. Together, they examine the lens' advantages in managing spherical aberration, its benefits for post-corneal refractive patients, and how it compares to other intraocular lenses (IOLs) in the field.
