An ophthalmic surgical system , comprising: a light source configured to generate a light beam ; a filter wheel disposed between the light source and an intraocular illumination device , the filter wheel including a clear area that allows substantially all wavelengths to pass through unimpeded; a first filtered area configured to limit transmission of a first range of wavelengths of the light beam to the intraocular illumination device; and a second filtered area configured to limit transmission of a second range of wavelengths of the light beam to the intraocular illumination device; and an actuator configured to selectively move the filter wheel to cause the light beam to pass through at least one of the clear area, the first filtered area, and the second filtered area of the filter wheel; and characterized by a computing device in communication with the actuator and configured to: monitor the wavelength ranges of the light that has been transmitted to a surgical field by the intraocular illumination device ; and automatically rotate the filter wheel based on an amount of blue light included in the light being transmitted to the surgical field such that the light beam passes through at least one of the clear area , the first filtered area , and the second filtered area . a light source configured to generate a light beam ; a filter wheel disposed between the light source and an intraocular illumination device , the filter wheel including a clear area that allows substantially all wavelengths to pass through unimpeded; a first filtered area configured to limit transmission of a first range of wavelengths of the light beam to the intraocular illumination device; and a second filtered area configured to limit transmission of a second range of wavelengths of the light beam to the intraocular illumination device; and an actuator configured to selectively move the filter wheel to cause the light beam to pass through at least one of the clear area, the first filtered area, and the second filtered area of the filter wheel; and a clear area that allows substantially all wavelengths to pass through unimpeded; a first filtered area configured to limit transmission of a first range of wavelengths of the light beam to the intraocular illumination device; and a second filtered area configured to limit transmission of a second range of wavelengths of the light beam to the intraocular illumination device; and an actuator configured to selectively move the filter wheel to cause the light beam to pass through at least one of the clear area, the first filtered area, and the second filtered area of the filter wheel; and characterized by a computing device in communication with the actuator and configured to: monitor the wavelength ranges of the light that has been transmitted to a surgical field by the intraocular illumination device ; and automatically rotate the filter wheel based on an amount of blue light included in the light being transmitted to the surgical field such that the light beam passes through at least one of the clear area , the first filtered area , and the second filtered area . monitor the wavelength ranges of the light that has been transmitted to a surgical field by the intraocular illumination device ; and automatically rotate the filter wheel based on an amount of blue light included in the light being transmitted to the surgical field such that the light beam passes through at least one of the clear area , the first filtered area , and the second filtered area . <EOS>
