The principle of Weis procedure is to split the lower lid transversely to create a fibrous tissue scar barrier which prevents the upward movement of the pre-septal muscle. This is combined with everting sutures which shorten the lower lid retractors and transfer their pull to the upper border of the tarsus.
This procedure gives a long term cure of an entropion with little horizontal lid laxity.
