The goal of dry eye treatment is not only temporary lubrication, but identifying the cause: is the problem tear quantity, tear-film quality, or inflammation of the ocular surface and eyelids? Once the cause is known, appropriate treatment can be selected instead of relying only on lubricating drops.

When Should You Be Evaluated?
An eye examination is recommended when dryness is recurrent or does not improve adequately with lubricants.
- Persistent redness or burning.
- A gritty or foreign-body sensation.
- Blurred vision that improves with blinking.
- Recurrent eyelid inflammation.
- Frequent use of lubricants without adequate improvement.
In the Clinic
The ocular surface, tear film, eyelids, and meibomian glands are evaluated to identify the type of dry eye and build the appropriate plan.
- Determine whether the dry eye is aqueous-deficient or evaporative.
- Evaluate the eyelid meibomian glands.
- Assess associated inflammation.
- Select treatment appropriate for each case.
1. Definition of Dry Eye
What Is Dry Eye?
Dry eye is a disorder of the ocular surface and tear film that causes tear instability, reduced tear volume, or poor tear quality. Symptoms may include burning, a gritty sensation, redness, reflex tearing, intermittent blurred vision, or a feeling of heaviness in the eyes.
Although it may seem simple, chronic dry eye can be associated with inflammation of the ocular surface, eyelids, or meibian glands. It may therefore require a stepwise treatment plan rather than a lubricating drop alone.
2. Causes of Dry Eye
Common Causes
Dry eye has many causes, and more than one may be present in the same patient.
- Reduced tear production by the lacrimal gland.
- Meibomian gland dysfunction, causing tears to evaporate too quickly.
- Chronic blepharitis or crusting around the eyelashes.
- Prolonged screen use with reduced blinking.
- Dry air, air conditioning, dust, or direct airflow.
- Contact lenses.
- Certain medications, including some allergy, acne, depression, or diuretic medicines.
- Hormonal changes, particularly with increasing age.
- Certain autoimmune or systemic diseases that affect tear production.
- After some eye surgeries such as vision correction or cataract surgery; dryness may be temporary or require treatment depending on the case.
3. Types of Dry Eye
Type 1: Aqueous-Deficient Dry Eye
Also called secretory or aqueous-deficient dry eye. In this type, the aqueous tear volume is insufficient to lubricate the ocular surface and may be associated with reduced lacrimal gland function, aging, systemic disease, or certain medications.
- Patients often experience persistent dryness.
- Frequent lubrication or anti-inflammatory treatment may be required.
- Selected patients may benefit from retaining tears on the ocular surface with punctal plugs after medical assessment.
Type 2: Evaporative Dry Eye
In evaporative dry eye, tear volume may be present but the lipid layer that slows evaporation is inadequate because of meibomian gland dysfunction or blepharitis, causing tears to evaporate rapidly.
- It is often associated with warmth or heaviness of the eyelids.
- There may be crusting around the lashes or blockage of the meibomian glands.
- Treatment focuses on the eyelids and meibomian glands, not only lubricants.
Mixed Type: Reduced Tear Production with Evaporation
Many patients have a combination of both types: reduced tear volume together with rapid evaporation related to meibomian gland dysfunction. Treating only one component may not be enough, so management may combine lubrication, control of inflammation, and improvement of eyelid and gland function.
4. General Treatment
General Treatments Used Across Dry Eye Types
These options may be used in many forms of dry eye, but their selection and sequence depend on severity and cause.
- Lubricating eye drops; preservative-free formulations may be preferred when use is frequent.
- Lubricating gel or ointment before sleep in selected cases.
- Reduce direct exposure to air conditioning and dry airflow.
- Take breaks during screen use and blink more consciously.
- Warm compresses when meibomian gland dysfunction is present.
- Eyelid-margin and lash hygiene when inflammation or crusting is present.
- Treat associated ocular allergy or inflammation when present.
- Short courses of anti-inflammatory drops such as corticosteroids when indicated and under medical supervision.
- Cyclosporine drops or other topical immunomodulatory treatments in selected chronic cases.
- Punctal plugs in selected cases after inflammation has been controlled.
- Treat systemic conditions or review medications that may worsen dryness in coordination with the treating physician.
5. Treatment According to Dry Eye Type
Treatment of Aqueous-Deficient Dry Eye
The goals are to increase lubrication, reduce inflammation, and retain available tears on the ocular surface.
- Frequent lubricants, preferably preservative-free when used repeatedly every day.
- Lubricating gel or ointment at night for severe dryness or morning symptoms.
- Cyclosporine eye drops in selected chronic inflammatory dry-eye cases.
- Short-term anti-inflammatory drops when significant irritation or inflammation is present.
- Punctal plugs to retain tears in selected cases.
- Punctal cautery in rare selected cases when plugs are inadequate or unsuitable.
- Autologous serum eye drops in selected severe dry-eye or ocular-surface damage cases.
- Therapeutic or scleral lenses in severe cases to protect the ocular surface.
- Evaluate autoimmune or systemic causes when dryness is severe or unusual.
Treatment of Evaporative Dry Eye
Treatment focuses on the eyelids and meibomian glands because the main problem is often an inadequate lipid layer that normally limits tear evaporation.
- Regular warm compresses to improve meibomian gland secretion.
- Clean the eyelid margins and lashes to manage blepharitis and crusting.
- Treat meibomian gland dysfunction and obstruction.
- LipiFlow in suitable cases to improve meibomian gland function.
- E-EYE IPL sessions in selected cases of meibomian gland dysfunction or associated inflammation.
- Blephasteam or other eyelid-warming devices in suitable cases.
- Treat Demodex when present on the eyelashes or eyelids.
- Topical or oral antibiotics in selected cases of blepharitis or ocular rosacea according to medical assessment.
- Lubricants containing lipid-supporting components when appropriate.
6. Treatment of Mixed Dry Eye
When Reduced Tear Production and Evaporation Occur Together
Mixed dry eye is very common in clinical practice and often requires treatment of more than one component at the same time. Lubricants alone may not be enough, and eyelid treatment alone may also be insufficient.
- Lubricants selected according to dry-eye severity.
- Treat ocular-surface inflammation when present.
- Treat the meibomian glands and eyelids to improve the lipid layer and reduce evaporation.
- Cyclosporine drops or other anti-inflammatory treatments in appropriate cases.
- Dry-eye technologies such as IPL or LipiFlow when meibomian gland dysfunction is significant.
- Punctal plugs when aqueous deficiency is significant and after inflammation is controlled.
- Regular follow-up to adjust the plan according to response.

This article is for health education and does not replace an eye examination. Do not use corticosteroid drops or ointments, cyclosporine, antibiotics, or punctal plugs without medical assessment, because appropriate treatment varies according to the type of dry eye and the presence of inflammation, elevated eye pressure, or other conditions.
