A very successful treatment for dry eye disease is punctal occlusion. Tears are secreted onto our eyes and become part of the tear film. The tear film drains away from our eyes through a drainage channel. With punctal occlusion, your eye doctor inserts a small plug in one or more of these channels to slow the drainage of tears. By slowing the drainage, more tears stay on your eyes, relieving dry eye symptoms. The procedure is simple and can be performed in-office in just a few minutes.
