I would like to thank Andrei Nikolaevich Zhuk (an extremely competent doctor and a pleasant person) and the clinic as a whole for the treatment of my mother, Olga Fedorenko! She underwent two surgeries on her left eye: 10/22/2019 vitreoretinal surgery of the macula (retinal tear) and 01/15/2020 lens replacement. Thank you so much that my mom can see again!
