Dr. Steven A. Greenstein is the medical director and director of refractive surgery at the Cornea and Laser Eye Institute and the CLEI center for Keratoconus. He is a graduate of Harvard Medical School’s Cornea, Refractive, and External Disease fellowship at Massachusetts Eye and Ear Infirmary. During his time at Harvard, Dr. Greenstein had the honor of being one of twenty graduates to receive the prestigious Heed Ophthalmology Fellow Award.
Dr. Greenstein received his medical degree from the Albert Einstein College 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. Dr. Greenstein completed a one-year pre-residency fellowship at the CLEI Center for Keratoconus, where he concentrated his research on keratoconus and corneal cross-linking. Dr Greenstein has published a multitude of articles in prestigious medical journals, including Cornea and Journal of Cataract and Refractive Surgery, on CLEI’s corneal crosslinking (CXL) clinical trials and on the surgical management of keratoconus and corneal ectasia. In addition to these 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. Dr. Greenstein, with Dr. Gelles and Dr. Hersh, is a co-inventor of Corneal Tissue Addition Keratoplasty (CTAK), a surgical technique to treat Keratoconus.
