Dr. Steven A. Greenstein, following in Dr. Hersh’s footsteps, is a graduate of Harvard’s Cornea, Refractive, and External Disease completed a Cornea, Refractive Fellowship at Massachusetts Eye and Ear at Harvard Medical School. During his time at Harvard, Dr. Greenstein had the honor of being awarded the prestigious Heed Ophthalmology Fellow Award. Dr. Greenstein was one of twenty graduating ophthalmology residents to receive this award.
Dr. Greenstein received his medical degree from the Albert Einstein College of of Medicine where he graduated with a special distinction in clinical research. Dr. Greenstein completed an Internal Medicine Internship, prior to the start of ophthalmology residency training at Rutgers – New Jersey Medical School. Prior to and during his professional ophthalmic career, Dr. Greenstein worked closely with Dr. Hersh and The CLEI Center for Keratoconus in our research department. Dr. Greenstein completed a one-year pre-residency fellowship with us, where he concentrated his research on keratoconus and corneal cross-linking. Together, Dr. Greenstein and Dr. Hersh published a multitude of articles in prestigious medical journals, including Cornea and Journal of Cataract and Refractive Surgery, on CLEI’s corneal collagen crosslinking (CXL) clinical trial for the treatment of keratoconus and corneal ectasia. In addition to publications, he has presented at numerous scientific meetings. Dr. Greenstein has written many book chapters, including chapters in Cornea: Fundamentals, Diagnosis, and Management, one of the primary references for cornea surgeons around the world.
Ophthalmologist in New Jersey
Under the guidance of Dr. Hersh, Dr. Greenstein has assumed the primary surgical responsibilities of the practice. Dr. Greenstein is a clinical assistant professor at Rutgers – New Jersey Medical School, where he teaches future eye surgeons about LASIK, and other refractive surgery procedures. He is currently a member of the American Academy of Ophthalmology, American Society of Cataract and Refractive Surgeons, the Refractive Alliance, the Cornea Society, and the Society of Heed Fellows. Dr. Greenstein is also a Team Ophthalmologist for New York Jets Football team.
