Frequently asked

What our patients ask.

Direct answers about procedures, recovery times, candidacy and cost. If you don't find what you're looking for, contact us and a specialist will reply personally.

01
Am I a candidate for refractive surgery?

Candidacy is determined in a pre-assessment including corneal topography, pachymetry, refraction and fundus exam. At ViSTAR we only operate when it truly makes sense.

02
Does FemtoLASIK hurt?

No. We use topical anesthetic drops that completely eliminate pain. The procedure lasts about 10 minutes per eye.

03
How long is recovery?

For FemtoLASIK: functional vision in 24 hours. For PRK: 5 to 10 days. For cataract with Premium IOL: clear vision in 24–48 hours.

04
How much does surgery cost at ViSTAR?

Refractive surgery ranges from $25,000 to $45,000 MXN per eye. We offer interest-free payment plans.

05
What is a Premium IOL and why choose one?

A Premium Intraocular Lens replaces the crystalline lens and lets you see far, intermediate and near without glasses.

06
Do you treat keratoconus?

Yes. We offer corneal cross-linking, intrastromal rings and scleral lenses. Early topography-based diagnosis is key.

07
How long does refractive surgery last?

The corneal change is usually stable, though vision may shift over time due to age, presbyopia or other eye conditions — natural processes independent of the surgery.

08
What should I do on the day of surgery?

Come accompanied, with no makeup or perfume. The full visit takes between 60 and 90 minutes including prep and immediate post-op.

09
Do patients come from other cities or countries?

Yes. We receive patients from Chihuahua, New Mexico, Texas and Arizona. We coordinate prior virtual consultation and surgery in the same trip when possible.

10
What technology do you use in your surgeries?

We use femtosecond laser, excimer laser with active eye tracking, and Scheimpflug systems for 3D corneal topography. Alcon, Johnson & Johnson and Zeiss platforms.
