Keratoconus
Keratoconus treatment in Mexico: cross-linking, intracorneal rings, specialty lenses, and corneal transplant. I catch early keratoconus most exams miss.
Dr. Emmanuel Bolaños Betancourt: ophthalmic surgeon with subspecialty training in Cornea, Refractive Surgery, and Cataract Microsurgery. I practice at Hospital Aranda de la Parra Puerto Interior (20 minutes from León) and at Oftalmo-Visión Clínica Oftalmológica in downtown Silao.

Early diagnosis, effective control, and safe options for every stage of keratoconus
Just diagnosed, and the first thing on your mind is whether you’ll go blind? I answer that here: Can keratoconus make you blind? What can happen, and how to stop it.
Keratoconus treatment at Hospital Aranda de la Parra Puerto Interior, 20 minutes from León. I see patients from across Mexico and abroad, including forme fruste keratoconus and advanced cases that no longer tolerate contact lenses.
If you have already been diagnosed with keratoconus, or you have symptoms that concern you, schedule an evaluation with me. I will explain your diagnosis clearly, how far your cornea has progressed, and the treatment that fits your case.
What is keratoconus?
Keratoconus is a progressive corneal disease. The cornea loses its round shape and thins, forming a cone-like bulge. This distorts vision in a way that regular glasses often cannot fully correct.
It can affect one or both eyes, and usually appears during the teenage years or early adulthood.
Over time it can progress through stages, from forme fruste keratoconus (mild or subclinical) to more advanced stages (grade 2, 3, or 4), where the cornea is visibly deformed.
What are the symptoms of keratoconus?
- Distorted vision, like waves or shadows
- High sensitivity to light or glare
- Frequent changes in your glasses prescription
- Trouble seeing at night
- Gradual loss of visual acuity
- Poor tolerance to contact lenses
- Irregular astigmatism
How is keratoconus diagnosed?
To detect this condition accurately, I run a combination of studies in my office, all in one place:
Corneal topography: maps the shape of the corneal surface
Corneal tomography: evaluates thickness, elevation, and internal structure
Pachymetry: measures corneal thickness across different zones; key for catching the central thinning typical of keratoconus
Aberrometry: analyzes the complex optical aberrations keratoconus produces, the kind regular lenses cannot correct
Full slit lamp exam: lets me observe the curvature, clarity, and structure of the cornea directly, along with other clinical signs
With these studies I can also detect forme fruste keratoconus, the earliest stage, before symptoms appear.
What types or grades of keratoconus are there?
Keratoconus is classified by severity and stage of progression:
-
Forme fruste or subclinical keratoconus: No clear symptoms, but visible on corneal topography.
-
Grade 1-2 (mild to moderate): Visual distortion partially correctable with glasses or rigid contact lenses.
-
Grade 3-4 (advanced): Clear corneal deformity. Vision heavily affected. Many patients can no longer tolerate contact lenses.
What does someone with keratoconus see?
Many patients describe their vision as ghosting, double images, or blur with several edges. In advanced stages, even with glasses or magnification, vision stays poor and distorted.
This kind of distortion is not the same as ordinary nearsightedness or astigmatism. It comes from a corneal deformity that affects image quality at all times.
Can keratoconus cause blindness?
No, keratoconus does not cause total blindness, but it can cause severe visual disability if it goes untreated.
In its most advanced stages, it can keep you from studying, driving, or working without specialized optical aids or surgery.
That is why catching keratoconus early and stopping its progression matters so much.
How can keratoconus progression be stopped?
The most effective treatment to stop keratoconus progression is Corneal Cross-Linking (CXL).
This procedure strengthens the collagen fibers in the cornea using ultraviolet light combined with vitamin B2 (riboflavin), increasing its natural rigidity and strength.
It is also essential to avoid rubbing your eyes, since repeated microtrauma is one of the main drivers of progression. If you have allergies or itching, I treat those too, to lower that risk.
Until what age does keratoconus progress?
In most cases, keratoconus progresses until age 30 to 35. After that it tends to stabilize.
Some patients keep progressing beyond that age, especially with a family history, severe allergies, or frequent eye rubbing.
What is the treatment for keratoconus?
Treatment depends on how far the disease has progressed. I offer several safe, effective options in my practice:
1. Corneal Cross-Linking (CXL)
This is the main treatment I use to stop keratoconus from progressing.
- Strengthens the collagen fibers in the cornea
- Stops keratoconus from progressing further
- Recommended in early stages or when progression is documented
2. Specialty contact lenses
- Rigid gas permeable, scleral, or hybrid lenses
- Fitted to the irregular shape of the cornea
- Improve vision without surgery (in mild to moderate cases)
3. Intracorneal implants (rings)
- Placed within the thickness of the cornea
- Improve corneal shape and stability
- Indicated for grade 2 or 3 keratoconus with poor lens tolerance
4. Surgery for advanced keratoconus
- In severe cases (grade 4), a partial or full corneal transplant may be necessary
- This decision is made based on precise studies, after the options above have been exhausted
Do I see patients from across Mexico and abroad?
Yes. My office is inside Hospital Aranda de la Parra Puerto Interior, 20 minutes from León and minutes from Bajío International Airport (BJX). I treat keratoconus patients who travel from León, Silao, Irapuato, Guanajuato City, San Miguel de Allende, all of Mexico, the United States, Canada, and Latin America.
I am fluent in English, so the whole consultation can be in English. If you are traveling for diagnosis or treatment, I can coordinate with you so your visit counts, and, when possible, finish the studies and treatment planning in just a few days.

Want me to look at your case?
Send me a WhatsApp with the reason for your visit. I will tell you whether an evaluation makes sense and which of my two offices to come to, before you make the trip. The whole visit can be in English.
