If the opacity does not obscure more than one-third of the diameter of the cornea, I practise the operation as described for closed pupil complicated with cataract, and make the newly-formed opening extend from the opacity as nearly to the edge of the sclerotic coat as possible. The crystalline lens, whether transparent or opaque, is thee cut up, and a part placed in the opening of the iris, to act as a plug.* This is my method of practice where the opacity is not very extensive ; but when there is not above a line of the circumference of the cornea remaining clear, I then introduce the knife, though in a similar manner, at the external and upper part of the eye, in order to prevent the escape of the aqueous humour before the operation is completed, and make a perpendicular incision through the outer margin of the iris opposite to and extending
