Which statement accurately reflects Vladimir Filatov's 1935 corneal transplantation work?

• A. He used cadaveric corneas for transplant, stored at 2-4 degrees, and donors screened for infections
• B. He opened the Eye Bank for Sight Restoration in 1944
• C. He performed the first US transplant
• D. He was the first corneal recipient

Answer: (A)

Filatov’s 1935 corneal transplantation work showed that donor corneas from cadavers could be preserved at low temperatures (about 2–4°C) and then transplanted, proving that corneal tissue could be stored and banked for future use. He also emphasized screening donors for infections to reduce disease transmission, laying early groundwork for safer, stored corneal grafts. This focus on preserved tissue and safety is why this statement is the best fit. The other points refer to events or roles not tied to his 1935 work—opening an eye bank in 1944, performing the first US transplant, or being the first corneal recipient.
