Abstract: An ophthalmic visualization system can include an ocular lens positioned between a macular contact lens coupled to a procedure eye and a surgical microscope. The ocular lens can guide a light beam through the macular contact lens and into the procedure eye, and in combination with the macular contact lens generate an intermediate image of the procedure eye at an image plane between the procedure eye and the surgical microscope. The system can include a reduction lens positioned in the optical path between the surgical microscope and the ocular lens. The reduction lens and/or ocular lens can align a focus plane of the surgical microscope with the image plane. A method of visualizing a procedure eye in an ophthalmic procedure can include positioning an ocular lens and a reduction lens between a macular contact lens and a surgical microscope; and scanning the procedure eye with a light beam.

Abstract: An ophthalmic surgical microscope includes a beam coupler positioned along an optical path of the surgical microscope between a first eyepiece and magnifying/focusing optics, the beam coupler operable to direct the OCT imaging beam along a first portion of the optical path of the surgical microscope between the beam coupler and a patient's eye (an OCT image being generated based on a reflected portion of the OCT imaging beam). The surgical microscope additionally includes a real-time data projection unit operable to project the OCT image generated by the OCT system and a beam splitter positioned along the optical path of the surgical microscope between a second eyepiece and the magnifying/focusing optics. The beam splitter is operable to direct the projected OCT image along a second portion of the optical path of the surgical microscope between the beam splitter and the second eyepiece such that the projected OCT image is viewable through the second eyepiece.

Abstract: An optical system configured to display a composite image includes a projection system that overlays a projected image onto a projected image plane. The optical system further includes at least two eyepieces through which the composite image is viewable to a user and a lens system having a subject image plane viewable through the at least two eyepieces. The subject image plane includes a subject image. The projection system causes the projected image to appear on a projected image plane, viewable through the at least two eyepieces, to include the projected image and the subject image in the composite image. The projection system further includes an adjustable optical component that is adjustable to position the projected image plane relative to the subject image plane.
