Brillouin Microscopy for Corneal Biomechanics

In this interview about his Refractive Subspecialty Day talk at AAO 2022, Dr. Bradley Randleman discusses Brillouin microscopy, a non-invasive, non-contact method of measuring corneal biomechanics and long-term reduction of corneal strength after LASIK or PRK. Dr. Randleman has looked at the technique in a variety of populations and shown its ability to differentiate early-stage keratoconus from controls. His latest pilot study looks at the differences in corneal strength reduction between LASIK, PRK, and SMILE as measured by this technique. This better corneal imaging with actual biomechanical data may help doctors make choices among the procedures for more patient satisfaction.
