    摘要： An indirect contact lens is mechanically coupled to a surgical microscope during ophthalmic surgery, such as vitreoretinal surgery. The indirect contact lens rests on a cornea of an eye of a patient during the surgery but is supported by a surgical microscope attachment having multiple degrees of freedom to accommodate small movements of the eye while remaining aligned to an optical axis of the surgical microscope.

    摘要： A method and system perform an ophthalmic procedure on an eye having an optical path from the lens to the retina. An image of at least part of the eye is received in a data processing unit. The image includes the optical path. The data processing unit determines keep out zone(s) and identifies undesirable feature(s) based on the image. The keep out zone(s) include the retina. The data processing unit also selects one of the undesirable feature(s) for removal. At least part of the undesirable feature is outside of the keep out zone(s). Confirmation for removal of the undesirable feature is received in the data processing unit. In response to receiving the confirmation, a control unit controls a laser to perform laser removal the at least the portion of the undesirable feature without targeting any portion of the keep out zone(s).

    摘要： 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.

    摘要： Ophthalmic surgical devices, systems, and methods for regulating aspiration from a patient's eye are provided. A vacuum pump in fluid communication with an aspiration line provides fluid aspiration from a vitreous chamber of the eye through the aspiration line. A sensor disposed adjacent to or inside the eye determines sensor data relating to an intraocular pressure (IOP). The controller receives the sensor data and regulates the aspiration in response to changes in the IOP, such as by controlling the vacuum pump. The controller may determine whether a fluid infusion to the vitreous chamber through an infusion line is below a maximum infusion level, regulate the infusion in response to the IOP being below a threshold value and the infusion being below the maximum infusion level, and regulate the aspiration in response to the IOP being below the threshold value and the infusion being at or above the maximum infusion level.

    摘要： A surgical probe system comprising a surgical probe having an instrument tip, and at least one motion sensor located within the surgical probe that measures movement and orientation data. The system further includes a processor that is configured to determine movement and orientation of the instrument tip based on the movement and orientation data, and adjust at least one surgical parameter of the surgical probe based on the movement and orientation of the instrument tip to affect a predetermined surgical outcome.
