Punctal Occlusion

Punctal Occlusion is a procedure for management of dry eye and ocular surface disease by which one or more of the lacrimal puncta are occluded. Occluding the puncta increases or preserves the level of natural tears on the surface of the eye. Each of 4 puncta may be occluded temporarily with a collagen plug or gel (Lacrifill). For more permanent occlusion, a silicone plug is utilized. Any of these methods is reversible in that the plug may be irrigated through or removed.
