Keratoconus treatment in Allen ten minutes down US-75.
Cross-linking to stop it getting worse. CTAK to reshape what it already changed. Specialty lenses to make the day-to-day work. One cornea-trained surgeon, one facility, and the shortest drive of any city we serve.
Keratoconus usually shows up young. That is the part nobody explains at the first appointment.
It rarely announces itself. A prescription that moves twice in one year. A teenager who rubs their eyes through allergy season and cannot get the left one to sharpen no matter how the phoropter clicks. An optometrist who says the word keratoconus, hands over a topography printout, and refers you onward — which is where most families in Allen start reading rather than being told.
Here is the part that matters: in younger eyes keratoconus tends to move faster, and cross-linking cannot give back what has already been lost. It strengthens the collagen bonds in the cornea and halts progression. That makes the months after a diagnosis genuinely consequential, and it makes an early, honest assessment of whether the cornea is actually progressing more useful than a wait-and-see year.
Dr. Shehz is a cornea-trained surgeon performing FDA-approved cross-linking and CTAK corneal tissue addition at our Plano facility, roughly ten minutes from most of Allen on US-75. Consultations include corneal topography, pachymetry, and a progression assessment — the diagnostics that decide whether to treat now or monitor. We take referrals from Allen optometrists directly and send our findings back.
Cross-linking protects the cornea you still have. Everything about the timing follows from that one sentence.
i.
Progression decides, not the diagnosis.
Topography and pachymetry establish whether the cornea is actually changing. Some keratoconus is stable and wants monitoring, not a procedure — and we will say so.
ii.
Stabilizing is not the whole plan.
Cross-linking stops the decline. CTAK addresses the distortion left behind. Having both under one roof means the sequence is a clinical decision, not a referral.
iii.
Ten minutes, not a project.
Allen is the shortest drive of any city we serve. Mapping, consultation, and follow-ups fit around school and work instead of replacing a day.
02/Beyond stabilizing
Keratoconus has three separate problems. Most clinics only treat one.
A cone-shaped cornea is progressive, it is irregular, and it is hard to correct. Those are three different problems. Cross-linking answers the first by halting progression. It does not answer the second — a stabilized cornea is still a distorted one.
CTAK answers the second. By adding laser-shaped donor tissue inside your own cornea, it works toward a more regular surface, which is what makes the third problem tractable: glasses and contacts start working again. Which combination your eye needs, and in what order, is what the consultation is for.
03/Treatment options
The pathway runs in order. Stabilize, reshape, refine.
Which of these your eye needs, and in what sequence, comes out of the corneal maps rather than off a menu. Cross-linking is the time-sensitive one. Reshaping can wait for a stable cornea, and usually should.
Reshape without a transplant
CTAK (Corneal Tissue Addition)
A piece of sterilized donor cornea, laser-shaped to the map of your own eye and placed inside your cornea to round the cone back toward its natural shape. Nothing is removed, so a transplant stays on the table rather than behind you.
The FDA-approved treatment that uses riboflavin and ultraviolet light to strengthen the collagen bonds holding your cornea's shape. It does not reverse keratoconus — it stops it getting worse, which is why timing matters more here than anywhere else.
Scleral and rigid gas-permeable lenses vault over an irregular cornea and give light a smooth surface to pass through. Often the bridge between diagnosis and stability — and, after CTAK, frequently easier to fit and wear.
Three steps, in this order. Skipping one is how people end up stuck.
Keratoconus care is a sequence, and the order is not arbitrary. Stabilizing a cornea that is still changing comes first, because reshaping one that has not settled does not hold. Each step below answers a different question about your eye.

Stop the progression
Corneal cross-linking strengthens the collagen bonds holding your cornea's shape. It is the time-sensitive step: it protects the cornea you still have rather than recovering the cornea you had.

Reshape the cone
CTAK places a laser-shaped piece of sterilized donor tissue inside your own cornea, working the cone back toward a regular shape. Nothing of yours is removed, which is what separates it from a transplant.

Sharpen what is left
Once the cornea is stable and more regular, glasses or specialty lenses do the remaining work — and a more regular cornea is markedly easier to fit and more comfortable to wear against.
04/Getting here
The drive is the easy part.
The route
Straight down US-75 — about ten minutes from most of Allen. Ground floor, free parking, no garage to navigate.
A keratoconus consultation runs about 60–90 minutes and includes topographic mapping. Cross-linking and CTAK are both performed as outpatient procedures at our Plano facility.
Open Monday–Friday 8:00–5:00 and Saturday 9:00–3:00, with English- and Spanish-speaking staff. Questions before booking? Call 214-972-2020 and a human answers.

My teenager was just diagnosed with keratoconus. How urgent is this?
Worth an evaluation soon rather than at the next annual exam. Keratoconus tends to progress faster in younger eyes, and cross-linking halts progression rather than reversing it — so the cornea you protect is the cornea you keep. The consultation determines whether it is actually progressing, which is the question that sets the timeline.
What is CTAK, and how is it different from cross-linking?
They do different jobs. Cross-linking strengthens the cornea to stop keratoconus getting worse. CTAK adds a laser-shaped piece of sterilized donor tissue inside your cornea to round the cone back toward a more regular shape. Many patients benefit from both — stabilize first, then reshape.
Is CTAK a corneal transplant?
No. A transplant replaces your cornea. CTAK adds tissue within the cornea you already have and removes none of it, which is why it preserves more of your future options than a transplant does.
Does eye rubbing actually cause keratoconus?
Rubbing is strongly associated with progression, and it is one of the few factors you can control. If allergies have your teenager rubbing constantly, treating the allergy is part of treating the keratoconus — we will cover that at the consultation.
How far is the clinic from Allen?
About ten minutes straight down US-75. Ground floor with free parking — the shortest drive of any city we serve.
Will insurance cover this?
Most medical plans cover FDA-approved cross-linking when keratoconus is documented as progressive. Coverage for CTAK varies by plan. We verify your benefits before you commit and put any out-of-pocket portion in writing.
Still have questions?
Talk to our team, no pressure, no sales pitch. We answer the question, not the upsell.
Not sure where you are on the path? The mapping answers that.
Stabilize, reshape, refine — keratoconus care is a sequence, and corneal topography is what tells us which step your eye is on. The consultation is diagnostic before it is anything else.
A diagnosis is not a plan. Ten minutes away, you can get one.
Corneal mapping, a progression assessment, and a straight answer about whether cross-linking, CTAK, or monitoring fits your eye. About ten minutes from Allen on US-75. Call 214-972-2020 or book online.
