About Robert “Bob” J. Stevens

Mr. Stevens is currently Chief Technology Officer at CorneaGen, based in
Seattle, WA, specialized in cornea care through medical devices and
biologics. Previously, he worked at Novartis/Alcon Laboratories for
nearly 35 years. During his tenure, he spent more than 20 years leading
all research and design for surgical products in the field of
ophthalmology. The technology he helped bring to market significantly
impacted the practice of medicine and positioned Alcon as the leading
company in manufacturing of ophthalmic surgical products. Mr. Stevens
introduced several industry-leading innovations, including a proprietary
intraocular lens material, AcrySof, along with proprietary intraocular
lens designs, Viscoelastics and surgical instruments for both anterior
and posterior segment surgery.

Mr. Stevens’ experience in eye banking dates back to 1991 when he
received the Thoth Award for his role in developing a plan to support
U.S. eye banks during a crisis involving cornea preservative storage
media. The storage media used by 80 percent of the market was recalled
due to bacterial contamination, but the plan Mr. Stevens developed with
partners prevented a shut down of the corneal transplant business in the
U.S. Mr. Stevens has served on the University of Washington Eye
Institute Community Action Board. He earned his bachelor’s degree in
medical technology and his master’s degree in clinical microbiology from
the University of Washington.
