Examples from the Web for discission
After a cataract has been removed, either by discission or extraction, an opaque membrane is usually left.
Discission, di-sish′un, n. an incision into a tumour or cataract.
Although the operation of discission for after-cataract (capsulotomy) is simple it is not to be undertaken lightly.
These are the same as for discission, with the addition of a needle with a long cutting edge.
(ii) In dense capsular membranes following removal of a lens by discission in which a cutting needle cannot make a hole.
