  • An antiphogistic iridectomy is the surgical removal of part of the iris to reduce intraocular pressure in inflammatory conditions of the eye.
  • A basal iridectomy is an iridectomy which includes the root of the iris.
  • An optical iridectomy is the surgical removal of part of the iris to enlarge the existing pupil, or to form an artificial pupil, when the natural pupil is ineffectual.
  • A peripheral iridectomy is the surgical removal of a portion of the iris in the region of its root, leaving the pupillary margin and sphincter pupillae muscle intact. It is used in the treatment of glaucoma.
  • A preliminary iridectomy, or preparatory iridectomy, is the surgical removal of part of the iris preceding cataract extraction. It facilitates the removal of the cataractous lens.
  • A sector iridectomy, also known as a complete iridectomy or total iridectomy, is the surgical removal of a complete radial section of the iris extending from the pupillary margin to the root of the iris. A key-hole pupil is left by the removal of a wedge-shaped section of iris.
  • A stenopeic iridectomy is the surgical removal of a narrow slit or a minute portion of the iris, leaving the sphincter pupillae muscle intact.
  • A therapeutic iridectomy is the surgical removal of a portion of the iris for the cure or prevention of an ocular disease.

Famous quotes containing the word types:

    “The rank and file have let their servants become their masters and dictators.... Provision should be made in all union constitutions for the recall of leaders. Big salaries should not be paid. Career hunters should be driven out, as well as leaders who use labor for political ends. These types are menaces to the advancement of labor.”
    —Mother Jones (1830–1930)

    “The American man is a very simple and cheap mechanism. The American woman I find a complicated and expensive one. Contrasts of feminine types are possible. I am not absolutely sure that there is more than one American man.”
    —Henry Brooks Adams (1838–1918)

    “As for types like my own, obscurely motivated by the conviction that our existence was worthless if we didn’t make a turning point of it, we were assigned to the humanities, to poetry, philosophy, painting—the nursery games of humankind, which had to be left behind when the age of science began. The humanities would be called upon to choose a wallpaper for the crypt, as the end drew near.”
    —Saul Bellow (b. 1915)
