136:. Before the cauterization, the surgeon tests for the effectiveness of the local sedation. Depending upon the type and depth of the cauterization, it is effective for a few months to a few years, by which time the puncta can possibly regrow and reopen. In this case, cauterization can be repeated. It initially offers complete closure of the duct. It also obviates the need for a punctal plug. It is performed for one puncta per appointment. Depending on the need, it can eventually be done for all four puncta.

Some plugs are made of thermally reactive material. Some of these are inserted into the punctum as a liquid, and then harden and conform to the individual's drainage system. Others start out rigid and become soft and flexible, adapting to the individual's punctal size after they are inserted.

Cauterization can result in temporary redness for a few hours which is caused by the avoidable use of a protective cover over the eye. Any lasting sensitivity as a result of this cover can be reversed using short-term use of steroid eye drops such as those containing

The risks of punctal plugs are fairly small. There is a risk of eye irritation, excessive tearing (lacrimation), and, in rare cases, infection.
