My focus is on corneal and cataract surgery, particularly on corneal disease and corneal transplantation.

I chose to join the Mid-Atlantic Permanente Medical Group so I could focus on patient care and help my patients maintain a great quality of life.

What My Patients Say

I had cataract eye surgery on my right eye in November 2019, and the left eye in February 2020. Dr. Korchak is a very skilled ophthalmologist. He is very professional and compassionate. He took time to address all of my many questions. As I could tell, he took the same care for all of his patients that waited to see him. I can see clearly! Kudos to Dr. Michael Korchak. - VB
