1. A method for performing an enhanced visually directed procedure under low ambient visible light on a patient's eye, comprising:
acquiring, from a first high resolution photosensor, at least one first real-time high resolution video signal representing at least one view of the eye in at least one wavelength of light outside of the wavelengths of visible light;
acquiring, from a second high resolution photosensor, at least one second real-time high resolution video signal representing the at least one view of the eye in visible light;
acquiring the at least one first real-time high resolution video signal and the at least one second real-time high resolution video signal after light conditions are low enough such that an intensity of the light conditions is below a predetermined threshold of patient discomfort;
converting, via a processor, the at least one view corresponding to the at least one first real-time high resolution video signal at the at least one wavelength of light outside of the wavelengths of visible light into at least one wavelength of visible light;
displaying, via the processor, the at least one view corresponding to the at least one first real-time high resolution video signal including the at least one wavelength of visible light.
