25 years ago, Dr. Milton Chu MD performed a corneal transplant on my left eye with an amazing 90,% vision results and no rejection of the cornea. 25 years later I still haven’t experienced any rejection and I can still wear hybrid contacts with a very satisfactory sight at my 50 years of age. Thank you Dr Chu!!! I will always remember you. Sincerely Raul Gamboa Patient of Keratoconus for 30 years.
