Surgical procedures
Excision
of an eyeball
Indications include a blind, painful eye, a
blind, cosmetically poor eye, intraocular neoplasm and in cadavers for use in
corneal grafting.
Evisceration of
an eyeball
As a result of the danger of opening up
lymphatic spaces at the back of the globe, and thus favouring meningitis,
evisceration is to be preferred to excision in panophthalmitis. The sclera is
transfixed with a pointed knife a little behind the corneosclerotic junction,
and the cornea is removed entirely by completing the encircling incision in the
sclera. The contents of the globe are then removed with a curette, care being
exercised to remove all of the uveal tract. At the end of the operation the
interior must appear perfectly white.
Incision and
curettage of chalazion (meibomian cyst)
The lid margin is everted to allow the
application of a meibomian clamp. The ring of the clamp is placed on the
palpebral conjunctiva with the granuloma in the centre. An incision is made with
a sterile
blade in the axis of the gland. The herniating
granulomatous tissue is -removed with a curette and the gland is scraped clear.
