Dear Mr Walker, I would like to thank you and all your colleagues who set time aside to treat me beyond their other commitments to treat me so promptly and so efficiently when I came to the Vitreo retinol clinic on Monday for what might have been merely a routine appointment. I feel extraordinarily fortunate that I was able to be seen immediately in the emergency clinic and to be found a slot for the same day in time for me to get home to Oxfordshire that evening. I should be grateful if you could extend my thanks to your colleagues who helped facilitate this. All the nurses and other staff I encountered were extremely helpful. I feel very privileged to have received such kind and expert treatment in a world renowned eye hospital.
