Dan Reinstein
Physics Professor Neil Johnson invites Ophthalmologist and laser eye surgeon Professor Dan Reinstein during his Royal Institution Christmas Lectures series in 1999 to demonstrate how very high frequency ultrasound can be used to measure objects with 1 micron (thousandth of a millimetre) precision and how this is being applied to laser eye surgery beginning in the 1990’s. The VHF digital ultrasound technology developed by Professor Reinstein with colleagues at Columbia University Medical Centre in New York has led the development of systems to anaylize and correct the complications of corneal refractive surgery (the Artemis scanner), LASIK, PRK, LASEK and other forms of corneal surgery that lead to irregular astigmatism or irregular corneal surfaces in general. This video shows a very early prototype of the Artemis technology (in process of commercialisation by Arcscan Inc) being used to scan a small sweet and measure the sugar coating on it as well as a video of a patient being scanned. Professor Neil Johnson is now Professor of Physics at the University of Miami; Professor Reinstein is Medical Director of the London Vision Clinic in London (www.londonvisionclinic.com).
