Medical and Surgical Procedures

Eye

Excision of a lens affected by a cataract

Extracapsular cataract extraction (ECCE) and phacoemulsification are the two primary

ways to remove a cataract. In both surgeries, the central part of the lens is removed and

replaced with an artificial intraocular lens (IOL) implant.

Excision of the anterior segment of the lens capsule along with the lens, allowing for

the insertion of an IOL implant

Excision of the lens by inserting an ultrasonic probe whose sound waves break the

lens into tiny particles which are suctioned out of the eye and the IOL is implanted

(See Fig. 11–14.)

Surgical transplantation of a donor cornea (from a cadaver) into the eye of a recipient;

also called keratoplasty

Excision of a portion of the iris used to relieve intraocular pressure in patients with

glaucoma

Iridectomy is usually performed to create an opening through which aqueous humor

can drain.
