Well it's difficult to express the depth of transformation really. I lived with -13 since I was a teenager and only recently at the age of 53 did I elect to have the RLE with Professor Gartry. I no longer have to feel any sense of discomfort or impracticality from glasses or contact lenses and my vision is now better than I have experienced throughout my whole life. I cannot recommend enough the quality, dedication and expertise of David Gartry and all of his team.
