Lacrimal punctum implantation (obturation): how we help reduce lacrimation
Constant tearing, dry eyes, burning, and irritation are often associated not only with a lack of tear fluid but also with a malfunctioning tear film.
In such cases, punctal occlusion is an opportunity to preserve the natural hydration of the eye and reduce discomfort.
At the K+31 clinic, we perform the procedure after an accurate diagnosis, select the appropriate type of obturator, and monitor the results after placement.

When we recommend this procedure
Dry eye syndrome and lacrimal insufficiency
Punctal punctal implantation is most often used in patients with confirmed dry eye syndrome. Typically, patients complain of burning, a gritty sensation, unstable vision in the evening, rapid fatigue, and constant discomfort when working at a computer.
Sometimes, the patient is already using rewetting drops, but the effect is short-lived. In this situation, proper tactic can be an additional way to maintain the film.
When we recommend punctal occlusion:
- Dryness, burning, and a gritty sensation in the eyes
- Insufficient effect of rewetting drops
- Discomfort associated with tear film disruption
- Dry eye syndrome confirmed by examination
- Need for temporary tear fluid support
The procedure can be used to treat dry eyes after surgery, age-related changes, and chronic tear film instability.
Tearing, discomfort, and eye irritation
Many patients are surprised when a doctor suggests dry eye treatment for complaints of constant tearing. In practice, this is common. Due to irritation of the surface, the body begins to produce more tears, but they are unable to retain them on the cornea.
In such cases, treatment for tearing is aimed not at reducing tear production, but at restoring the stability of the film. If the problem is specifically related to disrupted surface hydration, punctal occlusion can significantly reduce discomfort.
When it's important to get a diagnosis first
We always conduct a diagnosis. The doctor evaluates the condition of the cornea, the function of the lacrimal glands, the condition of the tear film, and the patency of the lacrimal canals.
If the patient has an infection, inflammation, or severe tear drainage obstruction, the underlying cause must be treated first. Some conditions directly contraindicate the procedure.
"We always start with an accurate diagnosis, because with excessive tearing, it's important to understand the cause of the symptoms. If punctal occlusion is truly indicated, it can significantly reduce discomfort and improve the patient's quality of life. At K+31, we tailor the solution individually and always monitor the results after the procedure."
What is sectoral laser coagulation of the retina?
This method involves targeted laser treatment of a limited area of the fundus. The laser forms coagulates—small areas of tissue adhesion around the defect or thinning.
This helps the doctor isolate the problem area. The decision is made after an in-person diagnosis.
How does the sectoral technique differ from the barrier and panretinal methods?
The sectoral method is chosen for localized changes. Barrier laser coagulation, or barrier coagulation, helps isolate the tear or edge of a localized detachment. Panretinal treatment is used for other purposes, such as ischemia due to diabetic retinopathy. The extent of the procedure depends on the diagnosis.
Before treatment, we explain the purpose of each method.
| Procedure Type | When Applied | Volume of Treatment | Purpose |
|---|---|---|---|
| Sectoral | Localized Dystrophy, Rupture, Thinning | Single Area | Strengthen Risk Area |
| Barrier | Rupture or Localized Detachment Along the Edge | Along the Defect | Limit the spread of the process |
| Panretinal | Diabetic retinopathy, ischemia | Large area, excluding the macula | Reduce the impact of ischemia |
The doctor selects a specific method after examination, imaging, and risk assessment.
What are the results of the procedure?
Laser coagulation of the retina does not reverse the structure of damaged tissue. The doctor uses a laser to create adhesion points around the damaged area to reduce the risk of widening the tear or worsening the thinning. After the procedure, the condition of the fundus is monitored dynamically.

What is punctal implantation?
Punctural implantation is a modern procedure in which a doctor partially restricts the outflow of tears through the lacrimal ducts. This method is also known as punctal occlusion. To achieve this, a special lacrimal plug or obturator is placed in the area through which tears enter the lacrimal canaliculi.
Normally, the tear film should evenly cover the surface of the eye and protect the cornea from drying out. If tears drain too quickly through the lacrimal ducts, the surface begins to experience a moisture deficit. This is why many patients develop dry eye syndrome. The body may respond by compensatory tear production. This results in epiphora—constant or intermittent tearing.
Punctural occlusion helps retain tears on the surface of the eye longer. This reduces dryness, reduces irritation, and improves comfort throughout the day. The decision to perform therapy is made only by an ophthalmologist after an examination and assessment of the cornea's condition.
It's important to understand that not every tearing problem is caused by dry eyes. Sometimes the problem is caused by inflammation, blocked tear ducts, or eyelid diseases. Therefore, a diagnosis is essential before starting treatment.
