Learn more about me ...

I graduated as an ophthalmologist from the Barraquer Institute of America and as Cornea Specialist from the University of Texas at San Antonio. For over 20 years I have worked as a teacher and specialist in prestigious institutions of Colombia such as the Barraquer Clinic, FUNDONAL and the Caribbean Ophthalmology Clinic. Overseas, I was appointed scientific director of the Muscat Eye Laser Center in Oman for a few years.

I have learned and worked hand in hand with some of the best experts in cornea and cataract surgery worldwide. About 5 years ago I started my private practice and I currently work in offices in Bogotá and Ibagué. Throughout this career, I can say that over 7,000 people have benefited from my laser, cataract, transplant, and keratoconus procedures.

I am a member of the Colombian Society of Ophthalmology, Cornea Colombia and the American Academy of Ophthalmology.

I understand that trust is the most important thing for whoever puts his eyes on my hands, and I understand that it is only achieved by working with passion, loving what we do and honoring the truth that science brings us. My promise is to get to know you, understand your needs and offer the best technology to your eyes.

Laser Surgery to Live Without Glasses (Refractive)

Looking for your glasses before making your morning coffee?

You put on a mask and your glasses fog up?

Would you travel better if you didn't have glasses?

Have you ever thought what it would be like to do sports without glasses?

Are you a candidate for surgery?

Our promise is to understand your vision problems and your lifestyle to CUSTOMIZE your treatment in pursuit of VISUAL FREEDOM.

If you are an adult, your distance vision improves with glasses, you have stable optical correction, and your eyes are healthy, laser surgery may be for you.

What does the surgery do?

We use the excimer laser to carve the optical correction of the glasses directly into the cornea. In this way, the light entering your eyes will naturally focus on the fovea, which is the most sensitive part of the retina at the back of your eyes. The excimer laser can correct refractive defects such as nearsightedness, astigmatism, farsightedness and presbyopia.

Refractive surgery (better known as LASIK or PRK) is a painless procedure with minimal risks and a very short duration. In a few days you will be back to work, doing all your daily activities and enjoying life without glasses.

What is better, LASIK or PRK?

Both techniques achieve the same goal, visual freedom. PRK is preferred when corneas are thin or if there is mild dry eye. LASIK offers a faster recovery.

If I'm over 50, what are my options?

We see poorly up close after the age of 40-45 because the eye’s natural lens does not work well. Using a cell phone, a tablet or a computer without glasses becomes more difficult every day. Depending on the case, laser or phaco-refractive surgery can be performed.

Towards the age of 50, when cataracts begin to appear, a change of the natural lens for a refractive lens that improves near vision can be considered. Nowadays, there is a wide range of intraocular lenses that can be chosen according to the conditions of each patient.

Phakic Intraocular Lens Implantation

Do you depend on your glasses to do almost everything?

Are your glasses lenses too thick?

Feel you would look better without glasses?

I wear very thick glasses, can I have surgery?

If your nearsightedness is too high to be corrected by laser, phakic intraocular lens implantation provides an excellent combination of vision and safety.

Phakic intraocular lenses are made of a material similar to contact lenses, but are designed to be placed inside the eye, allowing the correction of high refractive errors, especially myopia.

For this surgery, it is required to apply drops that dilate the pupil, since the lens is implanted behind the iris. After applying anesthesia, we will create a very small incision at the junction of the cornea and the sclera, through which the lens will be injected into the eye. The surgeon makes sure that the lens is positioned properly and will check the eye pressure a few hours later.

The change in vision is AMAZING and will give you great satisfaction.

Cataract Surgery

You are over 50 years old and I ask you ...

Is your vision blurred, worse at night or when there is a lot of sun?

Do you have trouble driving at night or seeing things you used to see?

Has your vision with glasses changed?

What are Cataracts?

Cataracts are clouding of the lens of the eye that prevents light from reaching the retina.

If they affect your daily life; for example, if you don’t feel safe driving, can’t read or stumble, it may be time to have surgery.

Why do cataracts occur?

Cataracts are the leading cause of visual loss and blindness worldwide. They are related to age and other conditions such as Diabetes Mellitus, use of steroid medications, trauma and eye inflammation. If not operated, they continue to progress to blindness.

What does Cataract Surgery consist of?

During cataract surgery, the specialist makes a small incision through which the crystalline lens is removed with ultrasound equipment (phacoemulsification).

Subsequently, an intraocular lens is implanted to allow the passage of light and restore the patient’s vision.

How to choose intraocular lens?

Nowadays, the range of lenses that exist is enormous: they vary in the country of production, in the optics, in the filters they have, and many other characteristics. But for practical purposes, we can say that there are three types of intraocular lenses:

  1. Monofocal lenses: they improve distance vision and require the patient to wear glasses for near vision. If the patient has astigmatism, he/she will need glasses for distance and near vision.
  2. Toric lenses: If you have astigmatism, these lenses allow you to correct it. However, glasses are required for near vision.
  3. Multifocal and extended focus lenses: They allow you to achieve spectacle independence for both distance and near vision. They are ideal in healthy eyes for proper performance. Of all the above, they are the most expensive.


What is Keratoconus and how can it be treated?

About 25% of patients who consult for myopia or astigmatism surgery have keratoconus; weakening and deformation of the cornea associated with rubbing the eyes. Unlike healthy eyes, eyes with keratoconus are not candidates for LASIK surgery.

There are different degrees of keratoconus: In the initial degrees, glasses and contact lenses improve vision but in more advanced degrees they help only partially and additional procedures or surgeries are needed according to the degree of the disease.

Collagen Crosslinking

This procedure consists of the application of a special ultraviolet light that produces bonds between the collagen fibers to prevent the cornea from continuing to deform. It is used especially in very young patients who are at high risk of progression.

Intrastromal Rings

Intrastromal rings reduce corneal irregularity, improve astigmatism and myopia and allow us to avoid or delay the need for corneal transplantation.

Treatment with rings can be complemented with crosslinking and with glasses or contact lenses to improve vision.

Queratoplastia Semilunar

Semilunar keratoplasty consists of removing a thin crescent of tissue from the peripheral cornea to improve the curvature and avoid the need for transplantation. It is useful in young patients with advanced keratoconus who would not improve with intrastromal rings and would otherwise need a transplant. This technique does not require donor tissue but does require sutures that are removed after a few months. It is complemented with the previously mentioned alternatives.

Corneal Transplant

Before the development of crosslinking and intrastromal rings, transplantation was the only treatment option for patients with keratoconus. In this technique, the center of the diseased cornea is removed and replaced with donor tissue that is fixed with sutures. It is currently used for grade 4 keratoconus as well as for scarring and other corneal conditions.
