Ophthalmic surgical system with blue light filtering

Patent Number: 9386918

Patent Date: 2016-07-12

Patent type: utility

An ophthalmic surgical system can include a light source configured to generate a light beam and a filter wheel disposed between the light source and an intraocular illumination device. The filter wheel can include an unfiltered area, a first filtered area, and a second filtered area. The first and second filtered areas can limit transmission of certain wavelengths of the light beam to the intraocular illumination device. The system can include an actuator configured to selectively move the filter wheel to cause the light beam to pass through the unfiltered area, the first filtered area, and/or the second filtered area. The system can include a computing device configured to provide a control signal to the actuator. The computing device can be configured to provide a control signal to the actuator based on a beam location, a beam composition, an exposure time, and/or a limited visibility condition.
