Fit problems are cornea problems.
Shrinking wear time and repeated refits are usually the cornea talking. We map it before assuming the next lens design is the answer.
Scleral lenses can carry you a long way — until the wear time shortens, the fit fights back, and clear vision costs more discomfort than it returns. CTAK treats the cornea underneath rather than the lens on top of it.

It is a familiar arc. Soft lenses stopped correcting, so you moved to rigid gas-permeable. Those got uncomfortable, so you moved to sclerals, and those worked — genuinely worked — for a while. Then the wear time started shrinking. Midday fogging. A fit that needs revisiting more often than it used to. Another lens redesign, another adjustment, another few months.
Specialty lenses are excellent at what they do, which is giving light a smooth surface to pass through. What they cannot do is change the cornea creating the irregularity. Past a point, refitting is managing a symptom at increasing cost — and around the Addison business district, where the day is screens and air conditioning, that cost lands during every working hour.
CTAK works at the cornea instead. A femtosecond laser shapes sterilized donor tissue to your individual corneal map, and that inlay is placed within your own cornea to round the cone back toward a more regular shape. Patients frequently still wear correction afterward — but a more regular cornea is a cornea that is easier to fit and more comfortable to wear against. Addison is about twenty minutes up the Tollway or the PGBT.
A lens can bridge an irregular cornea. It cannot make the cornea less irregular.
Shrinking wear time and repeated refits are usually the cornea talking. We map it before assuming the next lens design is the answer.
The CTAK inlay is laser-sculpted from your own corneal map — a custom geometry, not a standard ring in a few sizes.
Reshaping and refitting are planned together here, so the lens that follows a procedure is fitted by people who know exactly what changed.
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.
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.
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.
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.
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.
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.
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.

Plan about 60–90 minutes. Bring your current lenses and, if you have them, recent fitting notes — how the lens sits tells us as much as the topography does.
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.

Talk to our team, no pressure, no sales pitch. We answer the question, not the upsell.
Repeated lens revisions are a signal, not a routine. Topography establishes whether the cornea is still changing — and whether stabilizing it, reshaping it, or refitting it is the honest next step.
Cost, safety, candidacy — the questions patients actually ask, answered in plain English in our patient education library.
