The long-term results of AlphaCor implantations, and evaluation of the main complications and risk factors were descrited. The survival rate of the device at 1, 2, and 3 years was 87%, 58%, and 42%, respectively.
The most significant complications were stromal melt (nine cases), optic deposition (three eyes), and retroprosthetic membrane formation (three eyes). The most common device-unrelated complication was trauma (three patients).
All complications were managed without loss of the eye. AlphaCor provides a treatment option for patients with corneal blindness in which a donor tissue graft would not succeed.
