Couching

Couching involves transferring the sheet of paper from the mould to the felt.

[C]ataract surgery has been employed for more than 20 centuries. The primary surgical technique for the large majority of this time was a procedure called couching. The first written description of couching is from an Indian surgeon, Susruta, circa 600 BC, involving the insertion of a needle into the eye and displacement of the lens out of the visual axis through either inferior or superior dislocation.
