Dr. Truong treats keratoconus, Fuchs’ dystrophy, keratitis, pterygium, and corneal scarring with medical care, corneal cross-linking, and corneal transplant surgery when it is needed.

Conditions
Which corneal conditions does Dr. Truong treat?
The cornea has to stay clear and evenly curved for you to see well. These are the most common conditions that change its clarity or shape:
- ✓Keratoconus. Progressive thinning that pushes the cornea into a cone shape, blurring and distorting vision.
- ✓Fuchs’ dystrophy. Loss of the endothelial cells that pump fluid out of the cornea, causing swelling and haze.
- ✓Keratitis. Inflammation of the cornea, often from infection, injury, or contact lens overwear.
- ✓Pterygium. A fleshy growth that starts on the white of the eye and can grow onto the cornea.
- ✓Corneal scarring. Scars from injury, infection, or surgery that block or distort light.

Treatments
Cornea treatments and procedures at Azure Eye Center
Most corneal conditions are treated without surgery at first. When surgery is needed, Dr. Truong replaces or repairs only the tissue that is damaged whenever possible.
Corneal cross-linking
Strengthens the collagen in a thinning cornea to help slow or stop keratoconus.
Corneal cross-linking →DMEK
Replaces only Descemet’s membrane and the endothelium, the layers that fail in Fuchs’ dystrophy.
DMEK and DSEK →DSAEK
Replaces the inner layers of the cornea with a thin donor graft for corneal swelling.
DMEK and DSEK →Penetrating keratoplasty (PKP)
A full-thickness corneal transplant when both the front and inner layers are damaged.
Advanced corneal treatments →Superficial keratectomy
Removes or smooths the outer layer of the cornea to clear irregular or cloudy tissue.
Advanced corneal treatments →Pterygium removal
Removes a growing pterygium that causes irritation or reaches toward the center of the cornea.

Corneal transplant options compared
Dr. Truong matches the type of transplant to the layer of the cornea that is damaged.
| Procedure | What is replaced | Often used for | Recovery |
|---|---|---|---|
| DMEK | Descemet’s membrane and endothelium only | Fuchs’ dystrophy and corneal swelling | Often the fastest visual recovery of any transplant |
| DSAEK | The inner layers, with a thin layer of supporting tissue | Fuchs’ dystrophy and corneal swelling | Faster than a full-thickness transplant |
| Penetrating keratoplasty (PKP) | The full thickness of the central cornea | Damage to both front and inner layers, deep scars, advanced keratoconus | Longest; vision can take a year or more to settle |
| Superficial keratectomy | The outer epithelial layer is removed or smoothed | Surface irregularity or haze in the outer cornea | A bandage contact lens protects the eye while it heals |
Symptoms
When should you see a cornea specialist?
Corneal symptoms can be mild or severe depending on the cause. Schedule a visit if you notice:
- ✓Eye pain, discomfort, or a scratchy feeling
- ✓Sensitivity to light
- ✓Excess tearing, mucus, or crusting
- ✓Redness that does not clear up
- ✓Blurred, hazy, or worsening vision
- ✓Glasses or contacts that no longer correct your vision
The cornea is one of the fastest-healing tissues in the body, so a minor scratch may resolve in days. A more serious injury or infection can quickly get worse. If symptoms are sudden or you wear contact lenses, call (817) 886-4600 the same day.

FAQ
Cornea specialist FAQs
What does a cornea specialist treat?
A cornea specialist treats diseases of the cornea, including keratoconus, Fuchs’ dystrophy, keratitis, pterygium, and corneal scarring. Care ranges from medicine and specialty lenses to cross-linking and corneal transplant surgery.
What is the difference between DMEK, DSAEK, and PKP?
They differ in how much of the cornea is replaced. DMEK replaces only the thin innermost layers, DSAEK replaces the inner layers with a little supporting tissue, and PKP replaces the full thickness of the central cornea.
How long does it take to recover from a corneal transplant?
It depends on the type. Partial-thickness transplants such as DMEK and DSAEK usually restore vision faster, while a full-thickness PKP can take a year or more for vision to fully settle.
Can keratoconus be treated without a transplant?
Yes, in most cases. Glasses or specialty contact lenses can improve vision, and corneal cross-linking can help slow or stop the cornea from thinning further. A transplant is reserved for advanced cases.
What causes a pterygium?
A pterygium is strongly linked to ultraviolet light exposure, along with wind, dust, and dry conditions. It is common in sunny climates like North Texas, and sunglasses help protect against it.
