Improvement of Eye Surgery Microscope Through Design and Construction of Adjustable Led Lighting System

Anterior eyeball surgeries require the use of microscopes with specific characteristics that provide, test and guarantee the surgeon and/or his assistants in the operating room the best possible image. By increasing the level of illumination, the long wave (IR infrared) that causes heating and suffocates the interior must be stabilized outside the spectrum used, as well as the short wave (blue-violet AV), since it is the part that damages the clear vision for the surgeon and/or TV camera, since it is related to fluorescence, spreading and apoptosis, it is about providing the ophthalmologist with resources to minimize light trauma in the patient’s eye. Some chromatic-light enhancement options from incandescent, fluorescent, and LED sources of specific Kelvin Temperature and high brightness were analyzed, both with delivery through multi-strand fiber optics and within a confocal microscope geometry configuration, the comparative analysis and choice of specific LEDs and their performance, constitutes the main result of this research. For this purpose, a power supply with power control by pulse length was expanded and built, also equipped with a thermal safety system to prevent LED overheating, mini radiators with a coolant pump as well as heatsinks were expanded and tested, and ventilation. The finished fountain, together with the cooling systems, are in themselves another result.
