More Information
Summary:Apparatus and methods are provided for interfacing an ophthalmic surgical laser with an eye using a patient interface (PI). The PI may include a closed, fluid-filled bladder having fiducials that contacts and deforms to the eye. Or, the PI may have an applanation lens with an 5 outer ring portion and an inner concave portion for receiving the apex of the cornea. Another PI features a suction ring with a flexible skirt for contacting the sclera that is non-circular and/or non-planar. A system for injecting an index matching fluid into the area above the eye may also be incorporated. An integrated system includes a co-molded lens cone and attachment ring, with a lens window at the bottom of the lens cone which provides a sealed volume for vacuum 10 attaching a laser delivery system above the lens cone.
