(1) The surgeon may excise the chalazion through either the conjunctival
surface or the skin of the lid (see figure 1-3). The route of excision depends upon the
surface upon which the chalazion is located. Very fine silk suture on a swaged-on
needle is used if excision is through the skin surface. No suture is required if excision is
through the conjunctival surface.
(2) A chalazion set is used with other instruments, supplies, and sutures
according to the surgeon's preference.

the eyelid. A painful lump occurs in the skin and the abscess, which can form may
break through the surface and drain pus. Although the common treatment is application

f. Ptosis. Ptosis is a drooping of the upper eyelid. It can be caused by
neurological disorder, ocular conditions such as microphthalmus (abnormal smallness
of the eves), and local injury such as traumatic rupture of the levator muscle as well as
other malfunctions. Lid surgery may be indicated if other treatments cannot remove the
