Abstract: An orthokeratological contact lens includes a treatment zone extending radially outward from a center point and return and alignment zones extending radially outward from the treatment zone, the return zone shaped to create an empty hypertrophy volume between the lens and the cornea when the lens is applied to the cornea, wherein the treatment zone is shaped based on a target treatment curve as to cause collagen fibrils located in a stroma of a cornea to shorten and flatten the cornea in the treatment zone and to lengthen and steepen it in the return zone when the rigid contact lens makes contact with the cornea without putting excessive pressure on or compressing the cornea, the treatment curve being based on a difference between a first arc length determined when a load is applied to the cornea and a second arc length determined when no load is applied to the cornea.

Abstract: Embodiments of this application are directed toward an orthokeratological contact lens to be worn on a patient's cornea and methods for prescribing the same. The method may comprise receiving patient corrective parameters and generating a target treatment curve for a target zone, wherein generating the target treatment curve comprises calculating a difference of a first arc length determined when a load is applied to the cornea and a second arc length when no load is applied to the cornea. The contact lens comprises a parabolic lens having an inner surface configured to face an epithelium of the patient's cornea, wherein the parabolic lens is adapted to reshape the cornea by way of stromal remodeling via collagen fibril lengthening or shortening from the strain induced by the stress imposed by the unique lens design. The change in fibril length without a change in its chord diameter changes its radius of curvature and hence changes the radius on the corneal surface.

Abstract: The present invention provides an orthokeratological contact lens to be worn on a patient's cornea and methods for prescribing the same. The contact lens comprises a parabolic lens having an inner surface configured to face an epithelium of the patient's cornea, wherein the parabolic lens is adapted to reshape the cornea by way of epithelium tissue growth. In a pre-treatment configuration, an outer surface of the epithelium does not conform to the contours of the inner surface of the parabolic lens such that there exits a gap comprising a hypertrophy volume that is disposed between the epithelium and the parabolic lens.

Abstract: A dog muzzle or similar device attachable to a dog, and having attached thereto an accessory pod which can comprise or include a remotely actuable stun gun. The device further includes a quick release unit which allows the muzzle and stun gun to be released from the dog, and the quick release unit also is remotely controllable.

Abstract: A remotely controllable dog muzzle apparatus includes a cup-shaped snout shield to which is attached an accessory pod provided with stimulus generators such as a stun gun or sensors interactive with a physical environment of a dog fitted with the muzzle. In the preferred embodiment, the pod contains a stun gun having a pair of forward projecting electrodes, and a high voltage power supply having an ON/OFF control terminal connected to an electronic switch controlled by the demodulated output of a radio receiver. The apparatus includes a remote radio transmitter adapted to transmit coded signals on a modulated radio frequency carrier to the receiver, thereby actuating the electronic switch and causing high voltage electrical sparks to arc between the electrodes, the sparks encouraging a suspect to obey orders or have pain inflicted by the electrodes.
