Dry Eye Syndrome
Dry Eye Syndrome occurs when the eyes produce insufficient or poor-quality tears, leading to rapid evaporation. A stable tear film is essential for a healthy eye surface and clear vision. Inadequate lubrication causes inflammation and irritation, and while often chronic, the condition can be effectively managed with appropriate treatment.What Is Dry Eye Syndrome?
Tears do more than provide moisture – they protect the surface of the eye, support clear vision and help prevent infection. Dry eye develops when either tear production is insufficient or the tear composition is unstable.
In many cases, inflammation of the eyelids or tear glands contributes to symptoms. Over time, untreated dry eye can affect the integrity of the corneal surface and, in more advanced cases, impact visual quality.
Dry eye is increasingly common and may be influenced by:
- Ageing
- Hormonal changes
- Environmental exposure (air conditioning, wind, low humidity)
- Prolonged screen use (reduced blinking)
- Certain medications (including antihistamines, beta blockers and long-term eye drops)
- Contact lens wear
- Refractive surgery
- Underlying medical conditions such as diabetes or autoimmune disease
- Eyelid conditions such as blepharitis
- Identifying the underlying cause is essential to effective management.
Symptoms
Dry eye symptoms can vary in severity and may fluctuate throughout the day.
Common symptoms include:
- Stinging or burning sensation
- Gritty or sandy feeling
- Redness
- Eye fatigue
- Sensitivity to light
- Intermittent blurred vision
- Excessive watering (a reflex response to irritation)
- Reduced tolerance for reading, screen use or sustained visual tasks
If left untreated, moderate to severe dry eye can lead to ongoing discomfort and, in rare cases, corneal damage.
Next Steps
If you are experiencing persistent dryness, irritation or fluctuating vision, a comprehensive eye assessment can determine the underlying cause and severity.
Dry eye cannot be permanently cured, but with appropriate treatment it can be very well controlled. Early management helps prevent progression and improves long-term comfort.
Assessment & Diagnosis
Evaluation includes:
- Assessment of tear production and tear film stability
- Examination of the eyelids and meibomian glands
- Corneal surface assessment
- Identification of contributing environmental or systemic factors
Because dry eye is often multifactorial, treatment is tailored to the individual rather than applying a single approach to all patients.
Treatments
Treatment for dry eye focuses on improving tear quality, increasing tear volume, and reducing inflammation.
- Artificial Tears
Lubricating eye drops and ointments supplement the natural tear film and provide symptomatic relief. Preservative-free formulations are often recommended for regular use. - IPL (Intense Pulsed Light)
IPL is a non-invasive therapy used mainly for meibomian gland dysfunction. Gentle pulses of light are applied around the eyes while protective shields are worn. This stimulates gland function and improves tear quality. Multiple sessions are usually needed for lasting results. - Punctal Occlusion
Small plugs can be inserted into the tear ducts to reduce tear drainage, helping maintain moisture on the eye surface and improve comfort.
Recovery & Aftercare
Most dry eye treatments are performed in a clinic setting and involve minimal downtime.
Ongoing management may include lifestyle adjustments such as:
- Optimising screen habits
- Managing environmental exposure
- Reviewing medications where appropriate
- Supporting general health and hydration
Dry eye is a chronic condition that benefits from structured, long-term care. With the right management strategy, symptoms can be significantly reduced and visual comfort restored.
