The Scientists


MacuHealth Scientific Advisory Board
Professor Stephen Beatty

Professor Beatty is Honorary Lecturer in the School of Health Sciences, Waterford Institute of Technology. Professor Beatty graduated from the Royal College of Surgeons in Ireland in 1990, and trained as an ophthalmic surgeon in Dublin, Manchester, Birmingham, London and Geneva. He was a Consultant Ophthalmic Surgeon with a special interest in retinal disease from 2001 to 2015, when he made the transition into full-time research; Professor Beatty has over 150 peer-reviewed publications.

“The use of MacuHealth to improve vision in normal, healthy people is the most important advance in eye science since the invention of spectacles.”


MacuHealth Scientific Advisory Board
Felipe Medeiros, MD, PhD

Dr. Mediros joined Duke Ophthalmology as Professor in August 2017.  Prior to joining Duke, he was a full professor of ophthalmology the UCSD School of Medicine where he held the Ben and Wanda Hildyard Endowed Chair for Diseases of the Eye. He also served as medical director of the Hamilton Glaucoma Center, University of California San Diego and director of the Visual Performance Laboratory at UCSD.

Dr. Medeiros’s research focuses on the development of innovative methods to diagnose and detect glaucoma progression as well as on the assessment and prevention of functional impairment in the disease, the leading cause of blindness in the world. In his research, Dr. Medeiros evaluates the impact of eye diseases on activities of daily living, using innovative techniques such as virtual reality. His laboratory was the first to use virtual reality to predict a clinically relevant functional outcome in medicine. He has also concentrated on developing innovative brain-computer interfaces for objective and portable assessment of visual function in several diseases. His research has been funded by numerous federal and private grants. He is the principal investigator on a National Institutes of Health (NIH) R01 to evaluate functional impairment in glaucoma and on an NIH R21 for development of a new method for assessing functional loss in glaucoma. His research has been published in over 300 peer-reviewed publications including major ophthalmology journals, 40 book chapters and five books on the evaluation of the optic nerve, visual field, intraocular pressure, diagnosis and progression of glaucoma. His work has received over 11,000 citations with an h-index of 60, one of the highest in the field of Ophthalmology.

He received his M.D. from the University of Sao Paulo School of Medicine (1997), Ophthalmology Residency at University of Sao Paulo School of Medicine, (2001)

Two-year Glaucoma Fellowship at the Hamilton Glaucoma Center, University of California San Diego (UCSD), 2004 PhD in Vision Science University of Sao Paulo, Brazil, 2005.

MacuHealth Scientific Advisory BoardMihir “Max” Parikh, M.D.

Being the San Diego and Los Angeles Charger’s Team Ophthalmologist since 2003 and the founding partner of the Advanced Ophthalmology Institute in 1999, Dr. Parikh knows the value of precision and the importance of outcomes in vision enhancing surgery.  Having undergone the LASIK surgery himself in the year 2000, he uniquely understands the perspectives of both the patient and the surgeon.

Dual fellowship trained in refractive surgery/anterior segment surgery and Board-certified since the start of the century, Dr. Parikh has now performed over 25,000 refractive procedures.  His impressive patient list includes his immediate family, fellow eye doctors and numerous NFL players and coaches.  He specializes in LASIK, PRK, Corneal Inlays, Crosslinking, ICLs and Cataract surgery with the use of lasers and high technology lens implants.  He was one of the earliest surgeons to use the excimer laser and the femtosecond laser for lasik and cataract procedures.  He was the first surgeon in San Diego to implant the Symfony lens and the Raindrop Inlay.  Even today, there is only a small subset of eye surgeons who specialize in the niche of achieving targeted outcomes using multiple platforms and technologies.

Before dedicating his career to the field of medicine, ophthalmology and the super sub-specialty of refractive surgery, Dr. Parikh was involved in extensive laboratory research in molecular biology and biochemistry at the University of California, Irvine and in clinical research at the University of California, San Diego Burn Center.  He still remains active in FDA clinical trials with medical devices and pharmaceutical products.  He often reminds patients that although making glasses disappear may seem like magic, it is all based on solid science and evidence based medicine.

An award winning surgeon, Dr. Parikh was honored with the Laurence Mehlman Prize and the University of California Regents Scholar Award.  He attended the University of Michigan Medical School and completed his ophthalmology training at the New York Eye and Ear Infirmary of Mount Sinai.  His fellowship presentation on “The effects of intrastromal corneal ring implantation (INTACS) on nerve fiber layer thickness” was awarded Best Paper of Session at the national 2000 ASCRS conference in Boston, Massachusetts.  More recently, his medical peers have voted him as “San Diego’s Top Doc” in 2011, 2012, 2013, 2014 and 2015.

In his spare time, Dr. Parikh teaches ophthalmology and the concepts of refractive surgery to optometrists and ophthalmologists locally and at a national level.  He has been published and quoted in many medical journals and newspapers.  He is a consultant for several medical and health care companies.  He was elected President of the San Diego County Medical Society and he is an active board member on the San Diego Food Bank.   However, he most cherishes the time he spends with his family and living in the outdoor San Diego lifestyle—while wearing his non-prescription sunglasses, of course!
