Corneal Edema: Symptoms, Causes, and Treatment Options

Written by Medicover Team and Medically Reviewed by Dr Gargi Apte Jankar , Ophthalmologist

Corneal edema is a condition where the cornea, the clear front surface of the eye, swells due to fluid buildup. This can affect vision and cause discomfort. The cornea plays a key role in focusing light into the eye, so any swelling can lead to blurred or distorted vision. Early diagnosis and treatment help prevent lasting damage and support better eye health.

What are the Symptoms and Warning Signs of Corneal Edema?

Corneal edema often affects how you see and how your eyes feel. Early symptoms may seem mild but can become more serious without treatment.

Common Symptoms

• Hazy or Blurred vision
• Seeing halos or glare, especially around lights
• Eye discomfort or irritation
• Feeling like there's something in your eye

Severe Symptoms

• Eye pain
• Noticeable swelling of the cornea
• Vision that worsens over time

What Are the Different Types of Corneal Edema?

Corneal edema can appear in different forms, depending on what causes it and how it develops:

• Acute Corneal Edema: Sudden onset, often due to surgery, injury, or sudden rise in eye pressure. Needs immediate care.
• Chronic Corneal Edema: Develops slowly over time, commonly seen in conditions like Fuchs' dystrophy.
• Bullous Keratopathy: Severe swelling that forms painful blisters on the cornea, often requiring surgical treatment.

What Are the Common Causes and Risk Factors of Corneal Edema?

Fluid buildup in the cornea can occur due to various medical or external factors.

Causes

• Eye surgeries (especially cataract surgery)
• Eye injuries or trauma
• Glaucoma (high eye pressure)
• Fuchs' Endothelial Dystrophy (a hereditary corneal condition)
• Eye infections (e.g., herpes simplex keratitis)

Risk Factors

• Overuse or poor hygiene of contact lenses
• Aging
• Having a family history of corneal diseases
• Previous eye surgeries
• Poorly controlled glaucoma

How is Corneal Edema Diagnosed?

A thorough eye examination is needed to identify corneal swelling and determine its severity.

Diagnostic Tests

• Slit-lamp Exam: Allows doctors to view corneal swelling and cell damage
• Pachymetry: Measures corneal thickness to detect fluid buildup
• Specular Microscopy: Examines the health of the cornea's endothelial cells

At Medicover, we use advanced tools to assess the cornea and offer expert care by trained ophthalmologists for precise diagnosis and management.

What Are the Treatment Options for Corneal Edema?

Treatment depends on the cause and how severe the swelling is. Some patients improve with medication, while others may need surgery.

Medications

• Hypertonic saline eye drops or ointments to reduce fluid buildup
• Anti-inflammatory eye drops if inflammation is present

Special Lenses

• Bandage contact lenses to protect the cornea and relieve discomfort

Surgical Options

• DSEK (Descemet's Stripping Endothelial Keratoplasty): Replaces damaged inner corneal cells with donor cells
• Penetrating Keratoplasty (PK): Full corneal transplant for advanced or unresponsive cases

We offer both medical and surgical solutions customized to your condition, supported by expert ophthalmologists and advanced technology at Medicover.

When to See a Doctor?

You should consult a doctor if:

• Vision becomes blurry or foggy
• You feel persistent discomfort or pain in your eye
• You're recovering from eye surgery and notice unusual symptoms
• You wear contact lenses and experience changes in vision or irritation

---

What Is the Recovery Process After Corneal Edema Treatment?

Recovery depends on the cause and treatment type. Most patients see improvement with the right care.

What to Expect

• Regular follow-ups with your eye doctor
• Use of eye drops or medications as prescribed
• Avoid rubbing or touching the eye after surgery

We offer ongoing care, individual recovery plans, and lifestyle guidance to help you protect your vision.

What Precautions Can Help Prevent Corneal Edema?

While not all cases are preventable, you can reduce your risk with good eye care habits.

Prevention

• Practice safe and clean contact lens use
• Avoid overnight lens wear unless prescribed
• Use eye protection during sports or high-risk activities
• Manage existing eye conditions (e.g., glaucoma, Fuchs' dystrophy)

Complications (if untreated)

• Chronic vision problems
• Painful blisters on the cornea
• Permanent corneal damage
• Need for a full corneal transplant
