A cystitome is not an ophthalmic procedure
but is included in the "Ophthalmic
Procedures" section because it is an implement used in ophthalmology.
A cystitome is a very small specialised knife used to
cut the lens capsule of the eye
when performing an extracapsular cataract
extraction (i.e. removal of the cataract-affected lens only, with
the lens capsule left in place) or a capsulotomy.
A cystitome is suited to this purpose as it is appropriately
small in size and has a curved or hooked blade ideal for this particular
surgical procedure.
