Abstract: A system includes a resonant circuit having an inductor coupled to a piezoelectric oscillator. The system also includes one or more light emitting diodes (LEDs) configured to generate illumination based on an output of the resonant circuit. The system further includes a frequency generator configured to frequency modulate the output of the resonant circuit. In addition, the system includes a power supply configured to provide a voltage to the resonant circuit and activate a piezoelectric effect in the piezoelectric oscillator. The piezoelectric oscillator may include a piezoelectric material that is configured to undergo electrical distortion in response to an applied voltage from the power supply. The frequency generator can be configured to alter a capacitance and/or an inductance of the resonant circuit. The illumination can be applied to the retina or other tissue of a body to adjust a pH of cells in the tissue.

Abstract: An ophthalmic surgical instrument (10) for cutting the lens (76) of an eye (70) includes first (12) and second (14) handle members which are interconnected for movement between an open position and a closed position. A wire loop (20) extends from the first end (12a) of the first handle member (12). A plate member (22) is interconnected to the first end (14a) of the second handle member (14) and is disposed adjacent the wire loop (20). In the open position of the handle members (12, 14), the wire loop (20) is spaced apart from the plate member (22) to receive the lens (76) therebetween. In the closed position of the handle members (12, 14), the wire loop (20) contacts the plate member (22) to cut the lens (76) disposed therebetween as the wire loop (20) presses the lens (76) against the plate member (22) to thereby cut the lens (76 ).

Abstract: A method of shoeing a hoofed animal is provided and includes the step of forming a mold (12) having a general configuration of a shoe for the hoof (80). The mold (12) is filled with a liquid acrylic material (64). The hoof (80) of the animal is placed within the mold (12). The acrylic material is cured utilizing ultraviolet light (50, 52), such that the liqid acrylic material solidifies and is integrally joined to the hoof (80) without any intervening adhesive or mechanical attachment. The hoof (80) is then removed from the mold (12).

Abstract: A tubular surgical device (10) is provided for insertion into a cavity of a living body. The device (10) includes an elongated substantially hollow cylindrical tubular flexible conduit (12) having an exterior surface (14) for contact with the tissue of the cavity. The external surface (14) is coated with a hydrophilic material and is impregnated with an infection preventing material for absorption by the tissue of the cavity. The conduit (12) includes a bore (20) which is defined by an annular wall (22). The annular wall includes a plurality of axially spaced alternating annular ridges (24) and grooves (26) to render the conduit (12) flexible. A delivery system (42, 44, 46) is provided for the tubular surgical device (10) for supplying, replenishing, and delivering antibiotics and germicides to conduit (12) for absorption by the cavity tissue.

Abstract: An intraocular implant unit (20) having a lens optic (22) and a limb (24) integral with the lens optic (22) extending outward radially from a first margin portion of the lens optic (22). An arcuate rim (26) is centered on the end of the limb (24) and a flexible support strand (28) is rooted in a second margin portion of the lens optic (22). Flexible support strand (28) is capable of adjusting to various sized anterior chambers such that the intraocular implant unit (20) can be utilized with various sized anterior chamber diameters.

Abstract: A contact lens (14) for insertion into the cornea (20) of a patient is provided. The contact lens (14) includes a circular portion of a donor cornea (10) anteriorly curved for correction of the patient's vision. The contact lens (14) is posteriorly ground (16) to correspond to the curvature of the patient's eye. The posterior portion (16) of the lens (14) includes a depending axially posteriorly directed integral ring (18) for insertion into and retention by the patient's cornea (20).

Abstract: An artificial intraocular lens adapted to fixate in the sclera of the eye while positioned in the anterior chamber with supporting structure to prevent contact between the posterior surface of the lens and the iris, thus preventing postoperative glaucoma.

Abstract: An eye implant has an optical lens anteriorly convex and posteriorly planar supported on two diametrically opposed coplanar feet through two supporting members forming an arch. Each supporting member is unitary with the lens and rooted in one of the feet outside the perimeter of the lens to support the lens with the posterior thereof anterior to the plane of the feet. The lens is formed of a rigid biologically inert material. The supporting members are formed of soft biologically supporting material. The resulting structure, when fixed into the sclera of the eye, will change as to move the lens anteriorly when forces are applied to the feet upon contraction of the ciliary body.

Abstract: An intraocular implant unit having a lens (10) with a first limb (11) and a second limb (12) integral therewith and extending outward radially from opposite margins thereof. A long arcuate rim (13) is centered on the end of the first limb (11) and a short arcuate rim (14) is centered on said second limb (12) wherein the rims (13, 14) and limbs (11, 12) are substantially less in lateral dimension than the diameter of the lens (10) for minimizing the weight of the implant unit while assuring positive fixation.

Abstract: An artificial intraocular lens (10) for encapsulation in the posterior chamber of an eye includes a generally triangular base element (12) with an optic element (14) positioned therein and a pin (22) extending outwardly from one corner thereof. Following extraction of the natural lens, the artificial lens (10) is positioned in the capsular sac with the optic element (14) posterior to the pupil and secured in place by a combination of tissue scarring within the capsular sac and superior clipping of the lens (10) to the iris with the pin (22). Another embodiment (30) includes an optic element (34) mounted in a support element (32) having two pins (42) extending outwardly from the corners thereof.
