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.
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.
No. We use topical anesthetic drops that completely eliminate pain. The procedure lasts about 10 minutes per eye.
For FemtoLASIK: functional vision in 24 hours. For PRK: 5 to 10 days. For cataract with Premium IOL: clear vision in 24–48 hours.
Refractive surgery ranges from $25,000 to $45,000 MXN per eye. We offer interest-free payment plans.
A Premium Intraocular Lens replaces the crystalline lens and lets you see far, intermediate and near without glasses.
Yes. We offer corneal cross-linking, intrastromal rings and scleral lenses. Early topography-based diagnosis is key.
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.
Come accompanied, with no makeup or perfume. The full visit takes between 60 and 90 minutes including prep and immediate post-op.
Yes. We receive patients from Chihuahua, New Mexico, Texas and Arizona. We coordinate prior virtual consultation and surgery in the same trip when possible.
We use femtosecond laser, excimer laser with active eye tracking, and Scheimpflug systems for 3D corneal topography. Alcon, Johnson & Johnson and Zeiss platforms.
