Punctal Occlusion
One way to alleviate dry eye is to help the eyes to make better and longer use of the small amount of lubricating tears they do produce. This is accomplished by closing off the small funnel-like drain hole found in the inner corner of the upper and lower eyelids. This microscopic drain hole, called a punctum, can be closed with a tiny plug called punctal plug. The plug is essentially invisible to the naked eye, and can be placed in the two tear ducts, top and bottom, or in only the lower ducts, in one eye or both eyes.
Punctal plugs can be temporary (collagen inserts) or permanent (silicone). Collagen plugs dissolve a few days after insertion and are used to see if punctal occlusion helps your symptoms. Silicone plugs are also temporary, but often can remain effective for many months. If your dry eye symptoms disappear when collagen plugs are inserted, or if dry eye symptoms come back when silicone plugs fall out, Doctor Pabalan may advise permanent punctal occlusion, a minor surgical procedure done in the office.
Punctal occlusion is for those:
- who have been diagnosed with dry eye
- whose doctor has determined that punctal occlusion is the appropriate treatment for their condition
What to expect on procedure day:
Your treatment will be performed in an examination room. It does not require a surgery center. Once you have been checked in and settled comfortably, drops will be used to numb your eye; no injections or needles are used.
The ophthalmic technician will gently pull your eyelid up and ask you to look toward the outside of your head, away from your nose. Using a special applicator, the plug will be placed into the corner of your eye, then released. The applicator or another tool will then be used to gently push the plug into your natural punctal opening and you'll be asked to blink. Once collagen plugs get wet, they will expand to completely fill the opening. Silicone plugs seal the opening immediately. The entire procedure takes only a few minutes. Many patients report immediate relief from dry eye symptoms and resume normal activities immediately.
Realistic expectations:
Serious complications with punctal occlusion are extremely rare, but like any medical procedure, it does have some risks. If you experience side effects, your doctor can remove the plugs. Collagen plugs dissolve in a few days.
If you and your doctor decide that punctal occlusion is an option for you, you will be given additional information about the procedure that will allow you to make an informed decision about whether to proceed.
