Of course the underlying cause must be cared for, whatever it may beiris scissors, and cocaine 4%. Introduce between the lids the speculum. With the fixation forceps grasp the conjunctiva directly opposite the point of incision (on the opposite side of the cornea, understand), and thus control the eyeball. (A full dose of chloral hydrate is good in irritable patients). The keratome is inserted about a line from the corneo-scleral margin into the cornea, and introduce the blade so as to divide as little tissue as pos Fig. 49. Tumors.--Not much to be done. Simple and malignant, as met with elsewhere. If of sufficient import to render it necessary, excise them.
