Paul Klein, OD, of Broward Eye Care in Fort Lauderdale, Fla., uses instrumentation, such as an OCT, for early detection of ocular conditions. This allows him to monitor and treat patients in the practice rather than immediately refer them to ophthalmologists. ODs do a better job, he argues, of explaining ocular conditions and treatments and emphasizing the importance of nutraceuticals. Instruments also provide evidence to demonstrate the need for regular office visits for pre-treatment monitoring.
