DMEK Corneal Transplant
Descemet Membrane Endothelial Keratoplasty (DMEK)—the most advanced corneal transplant technique for endothelial cell disease, offering faster recovery and superior visual outcomes.
Superficial Corneal Scars & Dystrophy
Clouding of the anterior cornea from scarring (trauma, infection, surgery) or inherited dystrophies, causing blurred vision, glare, and visual disturbance.
Understanding Superficial Corneal Scars & Dystrophy
Superficial corneal scars and anterior corneal dystrophies affect the front layers of the cornea, causing clouding that interferes with clear vision. While the deeper corneal structures may be healthy, these surface abnormalities scatter light and reduce visual clarity.
Corneal scars can result from previous injury, infection (such as bacterial or viral keratitis), or complications from eye surgery. They represent the cornea's healing response but unfortunately create permanent opacity in the normally clear tissue.
Anterior corneal dystrophies are inherited conditions affecting specific corneal layers. Examples include epithelial basement membrane dystrophy (EBMD), Reis-Bücklers dystrophy, Thiel-Behnke dystrophy, and the anterior variants of granular and lattice dystrophy. These conditions can cause both visual symptoms and recurrent erosions.
Treatment depends on the depth and density of the opacity. Superficial problems may respond well to PTK (phototherapeutic keratectomy), which uses laser to remove the affected tissue. Deeper or more extensive involvement may require corneal transplantation.
Signs You May Notice
If you're experiencing any of these signs, a consultation can help determine the cause and appropriate treatment.
- Blurred or hazy vision
Clarity reduced as if looking through a dirty window
- Glare and halos around lights
Particularly noticeable when driving at night
- Fluctuating vision
Vision may vary with blinking or throughout the day
- Recurrent corneal erosions
Common in some dystrophies like EBMD
- May be asymptomatic if peripheral
Central opacities affect vision more than peripheral ones
Causes
- Previous corneal infection (bacterial, viral, fungal keratitis)
- Corneal injury or trauma
- Complications from previous eye surgery
- Inherited corneal dystrophies (genetic conditions)
- Chemical or thermal burns to the eye
Risk Factors
- History of corneal ulcer or infection
- Contact lens-related complications
- Family history of corneal dystrophy
- Occupational exposure to eye injury risk
- Herpes simplex virus infection affecting the eye
When to Seek Help
Consider booking a consultation if you notice any of the following:
- Your vision is affecting daily activities despite glasses
- You notice increasing haziness or glare
- A known corneal scar appears to be worsening
- You have family history of corneal dystrophy with visual symptoms
- You experience recurrent painful erosions along with visual symptoms
Frequently Asked Questions
Very superficial scars may fade somewhat over time, but most corneal scars are permanent. The cornea heals by forming scar tissue rather than regenerating clear tissue. However, treatments like PTK can remove superficial scars.
PTK (phototherapeutic keratectomy) uses laser to remove superficial corneal abnormalities and is suitable for conditions affecting only the front 10-20% of the cornea. Corneal transplantation is needed when deeper layers are affected or when the problem is too extensive for laser treatment.
Yes, most corneal dystrophies are inherited, typically in an autosomal dominant pattern. This means if one parent is affected, each child has a 50% chance of inheriting the condition. Genetic testing can sometimes confirm the diagnosis.
