Over his medical career, Professor Dan Reinstein has built an international reputation as a uniquely experienced and pioneering LASIK surgeon. His particular expertise in LASIK research and the systematization of surgical technique are key assets for his work with HCP. 

Professor Reinstein graduated from Cambridge University, and did his ophthalmology training at Mount Sinai Hospital in New York. During several years of research in ultrasound bioengineering at the Weill Medical College of Cornell University he led the development of the Artemis VHF digital ultrasound technology -  the most accurate diagnostic technology for measuring and studying the individual corneal layers as well as ocular dimensions of the anterior segment with one micron precision. Professor Reinstein has pioneered the application of the Artemis technology to the understanding of LASIK safety and accuracy, and is recognized as one of the leading authorities in the repair of the complications of LASIK. He developed Laser Blended Vision - the LASIK treatment for presbyopia (ageing eyes) now distributed as by Carl Zeiss in their MEL80 laser platform. Professor Reinstein has also developed new algorithms for the safe treatment of very high refractive error by LASIK. He brings exceptional expertise and experience accrued as the former Chief Medical Officer of a group of clinics across North America in which high standards of care and surgical systematization enabled over 100,000 procedures to be performed in one year by 58 surgeons in 28 clinics.

Concurrently with his medical career Professor Reinstein has been playing the saxophone for over 40 years including two years of study on a performance scholarship at the Berkley College of Music, Boston, and he is continuing to play jazz on a regular basis.

He is the founder and Medical Director of the London Vision Clinic where he practices full-time. For additional information on Professor Reinstein and his work please visit London Vision Clinic.
