David F. Chang MD has been passionate about phacoemulsification cataract surgery ever since he saw a medical student. He happened to see a video of Charles Kelman MD performing phaco and he was hooked. He has since gone on to become a true leader in ophthalmology with so many innovations and discoveries that improve the way that we all operate. He described IFIS: intra-operative floppy iris syndrome, studied endophthalmitis risk, compared MSICS to phaco, leads the way to reduce medical waste in ophthalmology, and so much more. I have personally known Dr Chang for 20 years and I learned so many new and interesting aspects about his life, philosophies, and his drive. I am confident that you will absolutely enjoy this podcast and learn so much.
