Am I a candidate for eye surgery?

Specialized evaluation in Mexico City to determine if you are a safe candidate for surgery and what type of procedure is right for you.

Not all patients are candidates.

And not all surgeries are suitable for all eyes.

Before considering surgery, it's essential to understand your eye.

The decision to have eye surgery isn't solely based on your prescription.

It's based on a detailed analysis of:

• Corneal structure

• Refractive stability

• Ocular surface (dry eye)

• Age and visual needs

• Associated diseases

• Patient expectations

In some cases, the best decision is not to have surgery.

General Candidacy Criteria (Guidelines)

Potential candidates:

• Over 18 years of age

• Stable prescription

• Structurally healthy cornea

• No active eye diseases

• Realistic expectations

More careful evaluation is required if you have:

• High myopia or hyperopia

• Irregular astigmatism

• High astigmatism

• Moderate or severe dry eye

• History of eye surgery

• Keratoconus or suspected keratoconus

• Prolonged contact lens use

Potential non-candidates:

• Progressive keratoconus

• Thin or unstable corneas

• Uncontrolled autoimmune diseases

• Active eye infections or inflammation

• Unrealistic expectations

Each case should be evaluated individually.

What type of surgery could it be?

There isn't just one type of surgery: it depends on your eye.

LASIK / PRK / SMILE / Etc.

For patients with suitable corneas and specific prescriptions.

ICL lens

An alternative for patients with high prescriptions or corneas unsuitable for laser surgery.

Requires adequate space within the eye (anterior chamber).

Cataract surgery (intraocular lenses)

Indicated when the lens has lost transparency or visual quality.

Also considered for age-related farsightedness (presbyopia).

Corneal management / complex cases

• Keratoconus

• Corneal transplant

• Combined surgeries

The choice is not based on preference, but on medical indication.

Risks and Limitations You Should Know

All eye surgery carries risks, including:

• Dry eye

• Halos or glare (especially at night and in patients with very large pupils)

• Refractive regression (especially with laser treatments)

• Need for touch-up surgery

• Rare but significant complications

The goal is not to promise perfection, but to improve visual quality safely.

Results: What to Really Expect

Not all patients achieve 20/20 vision (100% vision). Sometimes, functional vision is the goal.

Occasional use of glasses or contact lenses may be required.

Depending on age and visual preferences, a small amount of residual myopia is sometimes preferable.

Age influences the final result.

In complex cases, the goal may be to improve, not completely eliminate, the refractive error.

A sound surgical indication or exclusion is far more important than the technique or technology used.

What does the evaluation include?

Complete ophthalmological examination with slit lamp

• Evaluation of the ocular surface

• Precise refractive measurement

  • Distance vision

  • Near vision

• Dilation

In addition, depending on the case, the patient's existing complementary studies are reviewed, or further tests are ordered. It is important to emphasize that a thorough examination is paramount; patient care cannot be based solely on complementary studies.

• Corneal topography

• Aberrometry

• Biometry

• Etc.

This allows us to determine not only if you are a candidate for surgery, but also how to perform it safely.

It's not about having surgery.

It's about determining if you should have surgery.

In some cases, the best medical decision is to postpone or avoid surgery.

If you are considering eye surgery, it's normal to have questions:

• Am I really a candidate?

• Which surgery is best for me?

• What are the risks in my case?

• Is surgery worth it?

Your questions will be answered during the consultation.

In what cases are there usually doubts?

• Patients who have already been told they are candidates for surgery but are unsure.

• People with high myopia or thin corneas.

• Patients with dry eye or previous discomfort.

• Cases involving previous surgeries (LASIK, RK).

• People seeking to reduce their dependence on glasses without taking unnecessary risks.

Need a Second Opinion?

If you've already been evaluated and have doubts about the diagnosis or the type of surgery recommended, a thorough re-evaluation is advisable.

Some cases require a more in-depth analysis before making a surgical decision.

An inappropriate surgical indication can lead to complications that could have been avoided with a more comprehensive evaluation.
