Ophthalmic Surgical System with Moveable Light Filter

摘要

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.

1. An ophthalmic surgical system, comprising:
a light source configured to generate a light beam; a filter disposed between the light source and an intraocular illumination device, the filter including:
an unfiltered area;a first filtered area configured to limit the transmission of a first range of wavelengths of the light beam to the intraocular illumination device; anda second filtered area configured to limit the transmission of a second range of wavelengths of the light beam to the intraocular illumination device; an actuator configured to selectively move the filter to cause the light beam to pass through one or more of the unfiltered area, the first filtered area, and the second filtered area of the filter; and a processor in communication with the actuator and configured to:
detect a beam composition of the light beam transmitted by the intraocular illumination device within an eye; andbased on the detected beam composition, output a first control signal to modify the detected beam composition by causing the actuator to selectively move the filter to a first position such that a first portion of the light beam passes through the unfiltered area and a second portion of the light beam passes through the first filtered area or the second filtered area.
