Ophthalmologic Surgical Procedures Categories.

	Blepharoplasty - Plastic surgery of the eyelid. (Cline et al., Dictionary of Visual Science, 4th ed)
	Cataract Extraction - Surgical removal of a cataractous lens. (Dorland, 28th ed)
	Corneal Transplantation - Partial or total replacement of the cornea from one human or animal to another.
	Dacryocystorhinostomy - Surgical fistulization of the lacrimal sac for external drainage of an obstructed nasolacrimal duct.
	Eye Enucleation - The surgical removal of the eyeball leaving the eye muscles and remaining orbital contents intact.
	Eye Evisceration - The surgical removal of the inner contents of the eye, leaving the sclera intact. It should be differentiated from ORBIT EVISCERATION which removes the entire contents of the orbit, including eyeball, blood vessels, muscles, fat, nerve supply, and periosteum.
	Filtering Surgery - A surgical procedure used in treatment of glaucoma in which an opening is created through which aqueous fluid may pass from the anterior chamber into a sac created beneath the conjunctiva, thus lowering the pressure within the eye. (Hoffman, Pocket Glossary of Ophthalmologic Terminology, 1989)
	Iridectomy - Surgical removal of a section of the iris.
	Keratotomy, Radial - A procedure to treat myopia by cutting radial slits into the cornea to flatten it and thereby change its refractive properties.
	Lens Implantation, Intraocular - Insertion of an artificial lens following removal of the crystalline lens, usually after cataract extraction.
	Light Coagulation - The coagulation of tissue by an intense beam of light, including laser (LASER COAGULATION). In the eye it is used in the treatment of retinal detachments, retinal holes, aneurysms, hemorrhages, and malignant and benign neoplasms. (Dictionary of Visual Science, 3d ed)
	Orbit Evisceration - The surgical removal of the contents of the orbit. This includes the eyeball, blood vessels, muscles, fat, nerve supply, and periosteum. It should be differentiated from EYE EVISCERATION which removes the inner contents of the eye, leaving the sclera intact.
	Scleral Buckling - An operation for retinal detachment which reduces the size of the globe by indenting the sclera so that it approximates the retina.
	Scleroplasty - Plastic surgery of the sclera. This procedure is used frequently to prevent blindness and poor vision in children with myopia.
	Vitrectomy - Removal of the whole or part of the vitreous body in treating endophthalmitis, diabetic retinopathy, retinal detachment, intraocular foreign bodies, and some types of glaucoma.
