What it is
The cornea is the clear window at the front of the eye and the lens that does most of the focusing: its shape accounts for much of your prescription, and its transparency is what lets light reach the retina cleanly. This area covers both: correcting the prescription by reshaping the cornea, and treating the diseases that deform it, cloud it or inflame it.
Refractive surgery is not for everyone, or at any point in life: first the prescription, the shape and thickness of the cornea and the surface of the eye are studied, and with that it is decided whether surgery makes sense, with which technique, or not yet.
What's included
- Refractive surgery
- Corneal transplant
- Corneal disease treatment
Techniques and procedures
-
01
Refractive surgery
Reshapes the cornea with a laser to correct nearsightedness, farsightedness and astigmatism. There are several techniques (LASIK, PRK and their variants), and the choice depends on the thickness and shape of the cornea of each patient, not on a general preference.
-
02
Corneal transplant
Replaces the damaged cornea, in full or only the affected layer, with donor tissue. It is indicated when the cornea has lost its transparency or shape and there is no other way to recover it, as in advanced keratoconus or after scarring.
-
03
Corneal disease
Keratoconus, infections, scars, dystrophies and the ocular surface around them. Many can be managed without surgery if caught early: keratoconus, for instance, can be halted in its early stages before a transplant becomes necessary.
Who treats it
When to get checked
- You wear glasses or contact lenses and want to know whether you are a candidate for refractive surgery.
- Your prescription changes from one year to the next, especially the astigmatism.
- You see halos or double images with one eye covered.
- You have a red eye with pain, light sensitivity or a foreign body feeling that does not go away.
- You were diagnosed with keratoconus or have relatives with it.
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.

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.
