Treatment for Dry Eye

Punctal Plugs

Tiny devices that help your natural tears stay on your eyes longer

Punctal plugs are tiny, biocompatible devices inserted into the tear ducts (puncta) in the corners of your eyelids. By partially blocking tear drainage, they help your natural tears stay on the surface of your eye longer. This simple, in-office procedure can provide significant relief for people whose dry eye symptoms haven't fully responded to artificial tears alone.

How it works

Your tears normally drain through small openings called puncta, located in the inner corners of your upper and lower eyelids. These openings connect to channels that carry tears away from your eye and into your nose (which is why your nose runs when you cry).

Punctal plugs work like tiny stoppers in a sink drain. By partially blocking these drainage channels, they help tears stay on your eye's surface longer, keeping your eyes more lubricated throughout the day. The plugs are about the size of a grain of rice and are designed to fit comfortably without being felt.

Is this right for me?

This may be considered if you have:

  • Moderate to severe dry eye symptoms not fully controlled by artificial tears
  • Aqueous-deficient dry eye (your eyes don't produce enough tears)
  • Need to reduce your dependence on eye drops
  • Dry eye related to autoimmune conditions like Sjögren's syndrome
  • Contact lens discomfort related to dry eye

It may not be a good fit if you have:

  • Active eye infection or inflammation that needs to be treated first
  • Significant eyelid abnormalities affecting the puncta
  • Severe allergies — trapping allergens in tears could worsen symptoms
  • History of severe dry eye with active inflammation (may need treatment first)

Your eye doctor will examine your tear production and drainage to determine if punctal plugs could help your specific type of dry eye.

What to expect

1

Before

  • •Your doctor may start with temporary dissolvable plugs to see if you benefit
  • •No special preparation is typically required
  • •Continue your normal eye drop routine until your appointment
2

During

The procedure takes just a few minutes and is done in the office. Your doctor may apply numbing drops for comfort, then gently inserts the plug into the punctum. Most patients feel little to no discomfort — perhaps a slight sensation of pressure. No stitches or recovery time is needed.

After

  • •You can resume normal activities immediately
  • •The plugs should not be felt once in place
  • •You may notice improved comfort and reduced need for artificial tears
  • •Temporary plugs dissolve over days to months; permanent plugs can last years
  • •Follow-up appointments help ensure the plugs are working well
Punctal plugs are generally very safe. Rare complications include mild irritation, the plug moving out of position, or infection. Contact your eye doctor if you experience significant discomfort, swelling, or discharge after placement.
