“What an amazing job the team at Optical Express Glasgow have done. Dr David Teenan and his team have left me speechless. I am totally amazed by the results of my surgery."

Robert McMahon - Lens Replacement Surgery

“I feel incredible, somewhere between the bionic woman and a sheer miracle. One of the things which hammered it home was sitting with my 19-year-old daughter on the night of the second operation and being able to read her texts. Although I didn’t tell her that, obviously!"
