Scott Greenstein, M.D.

Center/Research Area Affiliations

Research Summary

Dr. Greenstein is a clinical innovator who seeks to improve current procedures. For example, he improved the design of a surgical instrument called the “toric axis marker,” which improves the accuracy of toric intraocular lens implantations—a procedure used to treat cataracts and astigmatism. The instrument allows him to more accurately determine the proper orientation for the implant. In addition to his clinical responsibilities, Dr. Greenstein also trains Harvard Medical School students and residents in the clinic, operating room, surgical training facility, and classroom. He is a diplomate of the American Board of Ophthalmology, a fellow of the American Academy of Ophthalmology, and a fellow of the American College of Surgeons.
