At North York Eye Clinic, the doctors can insert both dissolvable and permanent punctal plugs. Punctal plugs, also known as lacrimal plugs or tear duct plugs, are tiny devices used in ophthalmology to treat dry eye syndrome. These plugs are inserted into the puncta, which are the small openings in the inner corners of the upper and lower eyelids where tears drain from the eyes into the nasal cavity.
The purpose of punctal plugs is to block or partially block the drainage of tears from the eyes. By doing so, they help to retain the natural tears on the surface of the eye for a longer period, providing relief for individuals suffering from dry eyes. This can be especially beneficial for people with chronic dry eye conditions, where the eyes do not produce enough tears or the tears evaporate too quickly.
There are two main types of punctal plugs:
- Temporary or Dissolvable Plugs: These are typically made of materials like collagen or a special type of polymer. They are designed to dissolve or break down over time, usually within a few days to a few months.
- Permanent Plugs: These are made from more durable materials like silicone or other long-lasting substances. They are intended to remain in the puncta for an extended period, and they may need to be removed by a healthcare professional if they cause any discomfort or if they are no longer needed.
The decision to use temporary or permanent punctal plugs depends on the severity and duration of the dry eye condition, as well as the individual patient's needs and preferences. The insertion of punctal plugs is a relatively simple and minimally invasive procedure that is often performed in an optometrist's office. It's important to note that the use of punctal plugs should be supervised and recommended by a qualified eye care professional based on a thorough evaluation of the patient's eye health.
