As a retina specialist at Wills Eye Hospital in Philadelphia, the nation’s first eye hospital, Allen Ho ’84 performs surgery to improve patients’ vision—and in one case so far, to restore it.

In July, he implanted a bionic eye in 66-year-old Fran Fulton, enabling her to see shapes and barriers after ten years of complete blindness. The new Argus II Retinal Prosthesis System, which only six people in the US have, uses a video processor and a chip implanted into the eyeball to give vision. Fulton says receiving sight—although limited—was “breathtaking.” She and Allen told their story on CBS’s The Doctors in November.

Allen says his field of surgery is very precise. He mentors surgeons in training and does research, particularly in finding ways to prevent eye disease.

Allen stays in touch with his sprint football teammates and fraternity brothers. He attended his 30th reunion in June.
