3. Lacking naturalness or spontaneity; forced; contrived; feigned: "Sally greeted us with an artificial smile."

1. A curved disk of opaque glass or plastic, containing an imitation iris and pupil in the center, inserted beneath the eyelids and supported by the orbitl contents after evisceration (removal of the contents of the eyeball) or enucleation (surgical removal of an eye); it may be ready-made (stock) or custom made.
2. A prosthesis for placement in the orbit of an individual whose eye has been removed.

Enucleation is only done under drastic circumstances such as to remove a malignant tumor in the eye or to relieve intolerable pain in a blind eye. Following enucleation, an artificial eye (ocular prosthesis) is implanted as a cosmetic substitute for the real eye.

1. A deep stupor or unconsciousness and reduced organic activity resembling the natural state of motionless exhibited by certain animal species during winter: One use of artificial hibernation is the therapeutically produced medical condition that is caused by the use of drugs alone or drugs and hypothermia which greatly reduces the metabolic state (body activities) during surgical procedures; such as, open heart surgery.
2. The act of retiring into quiescence: The author emerged from his artificial hibernation to produce his first book after several years.
3. A condition of the retarded vital activity of an organism in warm-blooded animals, including humans, which is created in a simulated way, similar to the condition of an organism during the winter: Artificial hibernation can be created through nerve-blocking techniques which stop the neural and endocrine mechanisms of bodily thermoregulation or heat regulation.

Tetanus produced by a drug: such as, strychnine.
