    摘要: A laser chamber has angled reflectors that reflect acoustic and shock waves away from the laser discharge area to minimize acoustic and shock wave disturbances. The angled reflector may have different configurations to assist in the dissipation of the acoustic and shock waves. For example, the angled reflector may have a modulated reflective surface, such as having grooves or holes defined within the surface. Further, the angled reflector may have a reflective surface with acoustic and shock wave absorbing properties. The reflective surface with absorbent properties may be a felt metal or have multiple layered porous surfaces. In addition, the walls of the laser chamber may be modulated to assist in the dissipation of the acoustic waves and shock waves through absorption, scattering, and by generating interference within the reflected waves. Multiple layered porous surfaces may be used along the walls to absorb and scatter incident waves. The walls of the laser chamber may also be covered with an acoustic and shock wave absorbing material, such as felt metal. In other embodiments, the walls of the laser chamber are modulated with grooves, such as triangular or rectangular horizontal grooves, which scatter incident waves and generate interference within reflected waves.

    摘要: A patient interface for an ophthalmic system can include an attachment module, attachable to the ophthalmic system, and a contact module, configured to accommodate a viscoelastic substance between the patient interface and a procedure eye. The viscoelastic substance can include a fluid, a liquid, a gel, a cream, an artificial tear, a film, an elastic material, or a viscous material. The refractive index of the viscoelastic substance can be within a range of approximately 1.24-1.52 at an operating wavelength of the ophthalmic system. The patient interface can further include input ports, output ports, and a suction system. It can be an integrated design or a multi-piece patient interface. The viscoelastic substance can be provided by injection, on the cornea, at the contact module, or in a space bounded by soft elastic films or membranes, such as in a bag.

    摘要: An interface for coupling an eye to a surgical laser is disclosed. A lens cone includes a base ring opposite an apex ring. The base ring defines a first plane and is adapted to couple to the delivery tip of the laser such that the first plane has a predetermined position relative to the delivery tip. An applanation lens is affixed to the apex ring and has a surface disposed in a second plane such that the second plane is parallel to and has a predetermined position relative to the first plane. A gripper is engagable with the lens cone. An attachment ring is affixed to the gripper and is adapted to couple to the anterior surface of the eye. When the lens cone and gripper are engaged, the applanation lens contacts the anterior surface of the eye, placing the anterior surface in spatial registration with the delivery tip.

    摘要: A system and method for resecting and transplanting corneal tissue is disclosed. In a recipient cornea, a resection depth from the anterior surface of the recipient cornea is determined based upon a biomechanical model of the recipient cornea. A resection incision for resecting a posterior portion of the recipient cornea is made at the resection depth. Preferably, the incision is made using a surgical laser. Optionally, a contact lens may be placed against the anterior surface of the recipient cornea, wherein the shape of the anterior surface is conformed to the shape of the contact lens.

    摘要: A method for applanating an anterior surface of a cornea and coupling the eye to a surgical laser is disclosed. A interface is provided which has a central orifice and top and bottom surfaces. A suction ring is removably coupled to the bottom surface of the interface. The interface is positioned over an operative area of an eye, such that the suction ring comes into proximate contact with the surface of the eye. A suction is applied to the suction ring to stabilize the position of the interface relative to the operative area of the eye. An applanation lens is positioned in proximate contact with the operative area of the eye. Finally, the applanation lens is coupled to the interface to stabilize the position of the lens relative to the operative area of the eye.

    摘要: A disposable lens for reconfiguring the cornea of an eye for ophthalmic laser surgery includes a lens which has a flat anterior surface that is formed opposite a contact surface. A skirt surrounds the contact surface and extends outwardly therefrom to define a chamber. The skirt is formed with a groove which creates a suction channel between the skirt and the contact surface in the chamber. In its operation, the lens is positioned over the cornea and a vacuum pump is selectively activated to create a partial vacuum in the suction channel. Due to this partial vacuum, the cornea is drawn into the chamber where it is urged against the contact surface of the lens. The result of this is that the cornea is flattened into a configuration where the introduction of spherical aberration and coma into a light beam passing into the cornea is reduced or eliminated.
