摘要： An electronically controlled fixation light system is described for ophthalmic systems. The ophthalmic system can include an ophthalmic imaging device that generates an image of a portion of an imaged eye, a fixation light controller that includes an input module, configured to receive an input in relation to the image generated by the ophthalmic imaging device, and a control signal generator that generates an electronic fixation light control signal in response to the received input, and a fixation light source, configured to receive the fixation light control signal, and to generate a fixation light according to the received fixation light control signal. A surgeon can image a portion of an eye with the imaging device, determine a misalignment of the imaged eye relative to the imaging device based on the image, and control the fixation light with an electronic control signal to reduce the determined misalignment.

摘要： The present invention generally relates to a method and system for determining the position and alignment of a plane in relation to an intersecting axis and using that known position and alignment to allow for corrections to be made when using the plane as a reference plane. More particularly, the invention relates to a method and system for determining the angle of tilt of a planar surface in relation to a laser beam, and using the determined angle of tilt to calculate a correction factor to be applied to the laser beam. Briefly stated, the method and system ultimately calculates a correction factor, z-offset, that is applied when using the laser beam in a procedure.

摘要： Optical imaging techniques and systems provide high-fidelity optical imaging based on optical coherence tomographic imaging and can be used for optical imaging in ophthalmic surgery and imaging-guided surgery. One method for imaging an eye includes positioning the eye relative to a Spectral Domain Optical Coherence Tomographic (SD-OCT) imaging system, the eye having a first and a second structure, and imaging the eye with the SD-OCT imaging system by selecting one of a direct image and a mirror image of the first eye-structure and generating a first image-portion corresponding to the selected image of the first eye-structure, selecting one of a direct image and a mirror image of the second eye-structure and generating a first image-portion corresponding to the selected image of the second eye-structure, and suppressing the non-selected images of the first and second structures.

摘要： Systems and techniques for laser surgery based on imaging a target tissue by nonlinear scanning are presented. In one implementation, a method for guiding an eye surgery can include the steps of: positioning an eye in relation to an imaging system; creating first scan data by determining a depth of an eye target region at a first set of points along a first arc; creating second scan data by determining a depth of the eye target region at a second set of points along a second arc; determining target region parameters based on the first and second scan data; and adjusting one or more surgical position parameters according to the determined target region parameters.
