When your eyes burn, feel gritty, or become blurry between blinks, the problem may start along your eyelids. Tiny oil-producing glands help keep tears from evaporating too quickly. When those glands become clogged, eye drops alone may not fully address the cause.

At Alamo Eye Care, home of The Dry Eye Center of San Antonio, we evaluate what is disrupting your tears and recommend care tailored to your eyes. For appropriate patients, our in-office MiBo Thermoflo treatment can help improve oil flow and dry eye symptoms.
 

Why Clogged Eyelid Glands Affect Your Tears

Your meibomian glands release oils that form the outer layer of your tear film. This layer helps slow evaporation and supports a smooth, comfortable eye surface.

With meibomian gland dysfunction, or MGD, these oils may thicken or gland openings may become blocked. Less oil reaches the tear film, allowing moisture to evaporate faster. The resulting instability can contribute to irritation and fluctuating vision.

Even watery eyes can signal dry eye. Irritation may trigger extra tearing without correcting the underlying oil imbalance.
 

Signs Your Tear Film Needs Attention

Symptoms can overlap with allergies and other eye conditions, so an examination is important. Common concerns include:

• Burning, stinging, or a sandy sensation
• Blurry vision that briefly improves after blinking
• Redness or persistent eye irritation
• Excessive watering despite a feeling of dryness
• Contact lens discomfort or symptoms that worsen during screen use

For our San Antonio patients, long hours at a computer and direct airflow from fans or air conditioning can add to tear evaporation.
 

How MiBo Thermoflo Helps Address Blockages

MiBo Thermoflo uses controlled heat applied to the outside of the eyelids with a handheld treatment pad and gentle massage. The warmth helps soften thickened oils, making them easier to release from the glands.

Improving oil flow can support the tear film’s protective outer layer and may reduce discomfort associated with MGD. This treatment addresses a contributor to evaporative dry eye rather than simply adding moisture to the eye surface.

MiBo Thermoflo is an external heat and massage treatment. Its method differs from automated thermal pulsation systems, which use programmed heat and pressure.
 

What We Evaluate Before Treatment

Not every case of dry eye begins with clogged glands. Reduced tear production, inflammation, allergies, and other conditions may also contribute.

During your dry eye evaluation, we assess your symptoms, eyelids, tear film, and ocular surface. These findings help us determine whether heat-based treatment is appropriate or whether another approach should be part of your care.
 

Maintaining Comfort After Your Visit

MGD is often a chronic condition, so improvement may require ongoing management. We may recommend eyelid hygiene, appropriate home warming, lubricating drops, or other therapies based on your needs.

Results and treatment schedules vary. Follow-up visits help us assess your response and adjust your plan as needed. Screen breaks, complete blinking, and reducing direct airflow can also support everyday comfort.
