During the last few decades Electronics engineering is used more and more in the medical field, especially to aid surgeons in performing surgeries. Different light sources are needed for surgical applications depending on the range of color temperature that is required. Traditional light sources are xenon or halogen lamps emitting white light at varying color temperatures. Ophthalmologists performing vitrectomy procedures require illumination that provides high contrast and clarity. Use of fibers that are in the order of 700 micrometer or less is typical, as this allows the least invasive solution for the patient. A fully functional module of a multi-modal LED meeting specifications and programmable to vary the percentages of RGB components of light for clearer and enhanced vision, and an LED driver to control the LED using a microcontroller have been successfully identified and procured. This prototype is used to design and engineer a biomedical optical device for enhanced vision for ophthalmologists during vitrectomy.
