Catherine Cleary, MD

Dr. Catherine Cleary, MD, a corneal surgeon and a fellow of the Royal College of Surgeons in Ireland, worked in the COOLLab from January to December 2010 while she was a research fellow with Dr David Huang at the Doheny Eye Institute, University of Southern California.  During this time she performed research on applications of anterior segment Fourier-Domain OCT combined with femtosecond and excimer lasers to develop novel corneal transplantation techniques. This involved a series of experiments testing novel OCT-guided transplant techniques on eye-bank eyes.  Two papers based on this work have been accepted for publication in the journal Cornea.  She also worked on OCT applications used in guiding laser treatment of superficial corneal scars and opacities and on guiding accurate femtosecond laser keratotomy incisions for the treatment of high astigmatism following corneal transplantation.  Lastly, she collaborated on projects involving Fourier-Domain OCT imaging of the anterior chamber angle.  Following her year with the COOLLab, Dr Cleary returned to Ireland where she is now a faculty member at a University Hospital specializing in the treatment of corneal diseases.
