摘要： A cosmetic system and technique are provided for improving the texture and appearance of an individual's skin. The system includes an energy absorption modifier that may be applied to a portion of the individual's epidermis. The energy absorption modifier is designed to displace water within that portion. Energy from an appropriate laser or infrared lamp can then be directed to a treatment area beneath the epidermal layer without detrimental heat buildup in that area of the epidermis.

摘要： A keratome (10) and a method for using the keratome (10) for cutting a cornea of an eye (14) are provided which allow an operator to view the cutting operation as it occurs. The keratome (10) includes an annular housing (12) sized to contact the eye (14) and allow a portion (21) of the cornea to protrude therein. A motor housing (22) is mounted to the annular housing (12) for movement with respect thereto in a feed direction. A blade (36) is mounted by the motor housing (22) for movement in a cutting direction transverse to the feed direction, and a motor (26) mounted by the motor housing (22) is drivingly connected to the blade (36) to provide reciprocal movement thereof in the cutting direction. Movement of the motor housing (22) in the feed direction across the eye (14) accompanied by movement of the blade (36) in the cutting direction cuts the portion (21) of the cornea protruding into the annular housing (12), while an operator can view the cutting through the annular housing (12).

摘要： The multi-plane corneal incision form of this invention includes a frame member in the shape of a segment of a hollow sphere that fits over a patient's cornea. The inner surface of the frame member includes a protuberance that distorts the cornea when the frame member is placed against the patient's cornea. The frame member also includes an aperture adjacent to the protuberance to allow a surgical blade to pass therethrough. By carefully configuring the protuberance and aligning the aperture, a physician can insert a surgical blade into the aperture and through the distorted cornea in a planar fashion that results in a multi-plane incision in the cornea once the frame member is removed from contact with the patient's cornea.

摘要： A method for reducing irregular astigmatism and debris during lamellar surgery of the eye is practiced by preoperatively marking the corneal surface with a pattern or radial and pararadial lines. After making the incision, the incised corneal cap or flap is removed, followed by reshaping of the corneal stroma, irrigating the corneal bed to wash residual debris, and aspirating fluid from the eye. The corneal cap or flap is then repositioned on the cornea by realignment of the pattern of radial and pararadial lines.

摘要： The present invention provides a surgical technique and instrument kit that allows for subtle modification of the corneal curvature by interlamellar injection of a synthetic gel at the corneal periphery while sparing the optical zone. The gel viscosity, volume and disposition within the surgical annular track as well as the diameter of the track, width, depth, and location are all parameters in the refractive change obtained. Following ultrasonic pachymetry performed centrally and at a selected wound entrance located about 2.5 to 3.5 mm from the apex, a one millimeter or so wide, about 75-85% corneal thickness depth radial incision is performed with a micrometric diamond knife adjusted to about 86% corneal thickness. Inserted through the partial-depth incision, a corkscrew-like dissector or helicoidal spatula forms a 360.degree. annular track centered about the apex. A transparent gel is manually injected through the incision, filling the annular channel. Using a surgical keratometer mounted to an operation microscope, the final corneal power is adjusted by massaging and removing the gel as necessary during the primary procedure or subsequent procedures, as the GIAK technique is reversible.

摘要： A pneumatic control system for providing pressurized air and vacuum to ophthalmic microsurgical instruments. The pneumatic system is constructed in a drawer assembly to allow it to be readily inserted into or removed from a modularly constructed cabinet of a microsurgical control console.In addition, the pneumatic system improves upon existing pneumatic control systems by providing a third mode of microscissors operation from a single pneumatic port. The third mode is made possible by a high speed three-way solenoid control valve which provides rapid pulses of air to the pneumatic port.A second improvement involves the use of a pneumatic pressure transducer to monitor pneumatic pressure being supplied to the pneumatic system in order to recognize non-hazardous transient drops in air pressure which can occur under certain normal operating conditions. A third improvement relates to the use of an intraocular pressure accumulator downstream from a final solenoid-operated pinch valve, which reduces fluctuations in air pressure and has other advantages.

摘要： A method and apparatus for correcting refractive errors of the eye are disclosed. Accelerated reshaping of the corneal tissue is accomplished by administering one or more enzymes and/or other agents to the eye which temporarily soften the cornea. The cornea is thereafter fitted with a rigid contact lens or a series of lenses which have a concave curvature that will correct a refractive error. The softened cornea then rapidly reshapes its convex curvature to the concave curvature of the contact lens or series of lenses, thereby rendering the eye emmetropic. The enzymes and/or other agents then dissipate from the cornea, and the cornea "hardens" to retain the new emmetropic shape. After "hardening" has occurred, the lens rendering the eye emmetropic is removed.
