Treatment of Dry Eye

Punctal Occlusion

• Punctum and intra-canalicular occlusion are appropriate for certain patients with aqueous abnormalities, and it is important that a correct diagnosis is made to allow selection of suitable patients for the procedure.

Collagen plugs

• These are "temporary" ; that is they dissolve over 4 to 7 days. This allows them to be useful for diagnostic and prognostic purposes. In other words, they could be used to predict the likelihood of benefit.
• Plugs are available in a range of diameters (0.2mm, 0.3mm, 0.4mm, 0.5mm, and 0.6mm) and lengths (a "standard" 2mm and a shorter 1.6 mm).
