A low profile tongue scraper includes a handle and a scraping element extending from an end of the handle. A portion of the length of the handle is preferably curved to provide improved access to a bottom portion of the tongue and to reduce the tendency of the user to experience a gag reflex. The scraping element is rigid to facilitate removable of undesirable build-up on the tongue. The scraping element preferably extends from the handle at an acute angle relative to the handle. A plurality of tooth brush bristles are preferably formed on the other end of the handle.
摘要:
A blade and holder combination for use with a microkeratome, and including means for improving mechanical stability when the blade is reciprocated during cutting, as well as a peripheral configuration minimizing local nonuniformities. Blades in accordance with the invention have a generally hemispherical posterior geometry that include an adjacent centralized ovoid coupling aperture and a small centrally disposed access slot that may include indicia for denoting blade type. The hemispherical geometry minimizes both local deformities and the processing needed to assure that the product functions to provide a clean, uniform surgical result.

A contact lens applicator has an elongated housing defining an interior chamber for storing contact lenses, first and second triggers mounted on the housing, a depressor for depressing each eyelid where the depressor is drivingly coupled to the triggers, a pair of opposing wing-shaped members projecting outwardly from opposite sides of the rollers for providing a support surface for facilitating locating the apparatus over the eye, and a pusher assembly slidably mounted within the interior chamber for engaging a contact lens holder and applying a contact lens thereon to the eye when the triggers are actuated. The contact lens is stored in a cartridge within the elongated housing. The lens holder is movable within the cartridge upon actuating the pusher, and includes a predetermined amount of saline or other solution for defining appropriate conditions for storing the lens.

A cutting tool (20null) for a microkeratome (4) is disclosed. This cutting tool (20null) includes a blade handle (24) and a separate cutting blade (56). The blade handle (24) is mounted on the cutting blade (54) on a surface (64) of the blade (54) that also contains a cutting edge (80). This cutting edge (80) is defined by an intersection of the surface (64) and a first cutting edge surface (72). Cutting edge surface (72) actually extends between the major surfaces (60), (64) of the blade (56), which are oppositely disposed.

The invention describes a temporary intraocular lens for use in intraocular lens replacement therapy, and uses of the temporary lens for determining the refractive status of the eye in patients having lens replacement therapy. Also described are methods for manufacturing a temporary intraocular lens.

A sideshield eye protector is presented which includes a comfort and safety wing that is formed as a surface appendage thereon, and extends in a generally perpendicular direction from the surface of the sideshield along the contoured edge of the sideshield positioned closest to the wearer's face. The comfort and safety wing may be integral to the sideshield forming an integral structure therewith or removably attached thereto. The comfort and safety wing is oriented generally parallel with the facial surfaces and generally follows the proximate facial contours. A separate wing portion may be fabricated on both the upper and lower parts of each sideshield, the upper wing portion extending from the upper contoured edge of the sideshield which provides additional coverage over the upper portion of the eye orbits, temple and lower forehead area. The lower face about the lower eye orbit and upper cheek area has a generally parallel orientation with those facial surfaces.
摘要:
A multi-function surgical instrument for facilitating ophthalmic surgery of the eye (3) by laser means, included are a lower ring (1) and an upper ring (2). One or two intermediate rings may also be included. The lower ring (1) includes a central aperture (11) to capture the limbus and aid in positioning of the eye (3). Protuberances on the lower surface (18) of said ring (1), application of vacuum between the lower surface (18) of the ring (1) and the eye (3), or both may be used to more firmly grip the eye (3). Ports (14) disposed on the upper surface (13) of the lower ring (1) and connected to a vacuum source may be used to control hydration of the surgical field. Attached to structures of the lower ring (1) is a sterile platform (17) for reposing temporarily removed tissues (32) during the administration of laser pulses to other tissues. The upper ring (2) is disposed above the surgical bed. Ports (22) disposed along said upper ring (2) and connected to a vacuum source may be used to control smoke and splatters resulting from the ablative procedure and create additional airflow to further control hydration of the surgical field.

A microkeratome cutting blade assembly 10 includes a cutting blade 12 and a blade holder 14 attached to the cutting blade 12. The cutting blade 12 is keyed to aid in ensuring that a cutting blade 12 top surface 24 abuts the blade holder 14 during manufacturing.
摘要:
A device for inserting a flexible intraocular lens into an eye including a tubular member and a plunger. The tubular member includes a staging area, a lumen, and an open distal end. The staging area supports the lens in an unstressed state prior to engagement by the plunger. In the unstressed state, the optic of the lens is suspended in a pocket to avoid any substantial contact with interior portions of the tubular member. The plunger includes a slot in its distal tip for receiving and gripping the lens. With this construction, the lens can be inserted into the eye in one continuous motion. Further, the plunger holds the lens when the lens is moved out of the tubular member.
