What Is an Ophthalmological Consultation?

An eye exam Mexico City with Dr. Sebastián Diener is a complete medical evaluation of the visual system, performed by an ophthalmologist — a physician specialized in diagnosing and treating eye diseases — not just a prescription check. It’s designed for patients seeking a preventive checkup, experiencing visual symptoms, or requiring follow-up for an already diagnosed eye condition.

A general eye exam with Dr. Diener costs $1,500 MXN. Additional tests, such as visual field testing or retinal imaging, may have an extra cost depending on your case.

What Does an Eye Exam Include?

A complete exam combines several tests that assess both visual function and the structural health of the eye:

Visual Acuity and Refraction

Measures how sharply you see at different distances and determines the exact eyeglass prescription, if needed.

Biomicroscopy and Tonometry

The slit lamp is used to examine the eyelids, cornea, lens, and anterior chamber. Tonometry measures intraocular pressure, key to detecting glaucoma in its early stages.

Fundus Exam and Pupil Dilation

Using dilating drops, Dr. Diener examines the retina, optic nerve, and macula to rule out diabetic retinopathy, macular degeneration, and other conditions of the back of the eye. The American Academy of Ophthalmology recommends this type of comprehensive evaluation to catch eye diseases early, before symptoms appear.

If you are coming in with a child or teenager whose myopia keeps progressing, Dr. Diener offers a myopia control program with Stellest lenses, MiSight contact lenses and low-dose atropine.

Ophthalmologist, Optometrist, or Optician: What’s the Difference?

This is one of the most common questions before booking an appointment. An ophthalmologist is a physician and surgeon specialized in eye diseases: they diagnose, treat medically, and operate. An optometrist assesses visual acuity and fits glasses but has no medical training and cannot diagnose or treat eye diseases. If you have diabetes, a family history of glaucoma, eye pain, or sudden vision changes, an ophthalmologist — not an optometrist — is the right choice.

How Long Does an Eye Exam Take?

A complete exam with pupil dilation takes between 45 and 60 minutes, depending on the tests required. Follow-up visits or specific checks are usually shorter.

How Should I Prepare for My First Visit?

Bring your current glasses or contact lenses, a list of medications you take, and results from any previous eye tests you may have. If you’ll be having your pupils dilated, keep in mind that near vision may be blurry for 3-4 hours afterward, so it’s helpful to bring sunglasses and, if possible, avoid driving right after the appointment.

Frequently Asked Questions (FAQ)

How often should I see an ophthalmologist?

For adults with no risk factors, an annual check-up is recommended starting at age 40. From age 60 onward, or earlier if there is diabetes, hypertension, a history of glaucoma, or visual symptoms, exams should occur at least once a year or as medically indicated.

Yes. Refraction (precise determination of your prescription) is part of the complete exam. At the end, a corrective lens prescription is provided if needed.

Dilation with eye drops allows a wider, more detailed exam of the back of the eye (retina, optic nerve, and macula). It is essential for detecting diabetic retinopathy, glaucoma, macular degeneration, and other posterior segment conditions. Near vision may be blurry for 3-4 hours afterward.

It is recommended not to drive for the 3-4 hours following pupil dilation, since near vision is temporarily affected and light sensitivity increases. It’s helpful to bring sunglasses for the trip home.

An ophthalmologist is a physician and surgeon specialized in diagnosing and treating eye diseases, both medically and surgically. An optometrist is not a physician: they assess visual acuity and fit glasses but cannot diagnose or treat eye diseases. For symptoms like pain, persistent redness, or systemic conditions like diabetes, an ophthalmologist is the right choice.

A general eye exam with Dr. Diener costs $1,500 MXN. Additional tests (such as visual field testing or retinal imaging) may have an extra cost depending on your case. If you have health insurance, the procedure may be covered by your insurer.

Bring your current glasses or contact lenses, a list of the medications you take, results from any previous eye tests, and your insurance card if you have health coverage. If you’ll be having your pupils dilated, consider bringing sunglasses for after the appointment.

Seek immediate care if you experience sudden vision loss, severe eye pain, flashes of light accompanied by many new floaters, eye trauma, or a dark curtain covering part of your visual field. These signs can indicate retinal detachment, acute glaucoma, or other emergencies that require immediate evaluation.
