What it is
The cornea has to be clear and have a precise curve. When a disease, a scar or an infection clouds or deforms it, and neither lenses nor treatments bring vision back, it can be replaced with donor tissue.
Today the whole cornea is not always replaced: often only the diseased layer is, which shortens recovery and lowers the risk of rejection. Follow-up after the transplant is long and is part of the treatment.
Techniques and procedures
-
01
Penetrating keratoplasty
The cornea is replaced in its full thickness. It is indicated when the damage involves all its layers, as with deep scars.
-
02
Anterior lamellar transplant
Only the front layers are replaced and the inner layer of the patient is kept. It is common in advanced keratoconus.
-
03
Endothelial transplant
Only the inner layer, the one that keeps the cornea clear, is replaced. It is used when that layer fails, as in Fuchs dystrophy.
Who treats it
When to get checked
- You have advanced keratoconus and lenses no longer correct your vision.
- You have a corneal scar from an infection or an injury.
- Your vision is cloudy in the morning and improves over the day.
- You already have a transplant and notice a red eye, pain or blurred vision: get seen soon.
If any of these sound familiar, the sensible step is an assessment: that is where you find out what is going on and what to do about it.
General guidance. It does not replace an assessment by a specialist.

Notes
What is worth knowing about your eyes
-
Am I a candidate for refractive surgery?
It is not for everyone, or at any point in life: first we check your prescription, your corneal shape and the ocular surface.

The cornea is the window of the eye
When it loses clarity or changes shape, vision blurs even with the right lenses: a prescription that will not settle deserves an exam.

Dry eye: why it burns and what helps
It is rarely a lack of water: usually the tear film evaporates too fast. That is why drops alone are not always enough.

Frequently asked questions
What people ask us most before their first visit
Do I need a referral to book a visit?
No. You can book your consultation directly. If another doctor referred you, please bring their notes and any tests: they help us avoid repeating work that is already done.
How long does the first assessment take?
Between 30 and 60 minutes. It includes a full eye exam.
What should I bring to my appointment?
Your current glasses, a list of the medications you take and any previous eye tests or prescriptions. If you wear contact lenses, ask us how long before the visit you should take them out.
Will my pupils be dilated? Can I drive afterwards?
Often yes, especially for retina and glaucoma exams. The drops leave your vision blurry and light-sensitive for a couple of hours, so it is best to bring someone along or not drive back.
Where is the clinic?
In Santa Fe, inside an office tower: Prolongación Vasco de Quiroga 4001, Tower A, 5th floor, office 5. Allow a few minutes for the entrance and the elevator; the "Directions" button opens the route on the map.
