The technology
What is the excimer laser?
The excimer laser is a technology that reshapes the cornea with high precision to correct refractive errors such as myopia, hyperopia and astigmatism. The goal is to improve visual quality and reduce dependence on glasses or contact lenses.
The key to success is not “just the laser”, but the right selection of the candidate, the pre-operative measurements and a fully personalized surgical plan.
- A few minutesduration of the procedure per eye
- 2–3 daysusual return to work
What it corrects
Myopia, hyperopia and astigmatism
Myopia
Difficulty seeing far away. The laser adjusts the corneal curvature to improve focus.
Hyperopia
Difficulty seeing up close (and sometimes far away). Focus is optimized by changing the corneal shape.
Astigmatism
Distorted vision caused by an irregular cornea. The treatment aims to regularize focus.
Candidacy
Are you a candidate for laser surgery?
Successful refractive surgery starts with the right selection of the candidate. In general, you are a good candidate if:
- You have myopia, hyperopia or astigmatism
- Your prescription has been stable for at least one year
- You depend on glasses or contact lenses and want more freedom
- Your cornea has the right thickness and shape (confirmed in the evaluation)
- You have no active eye disease
If the study shows that laser is not your best option, we tell you clearly and propose the right alternative for your case, such as phakic intraocular lenses or lens surgery.
The evaluation
The pre-operative evaluation
Before recommending laser surgery we take detailed measurements to confirm that the procedure is right for your eye and to define the most precise treatment.
Safety depends on variables such as corneal thickness, topography, tear quality and refractive stability.
The personalized plan
- 01Complete refractive study and prescription stability.
- 02Topography and corneal analysis to plan the treatment profile.
- 03Ocular surface assessment (dryness, inflammation, tear quality).
- 04Discussion of goals: habits, work, night driving, sport.
Recovery
Fast recovery and increasingly sharp vision
The procedure is outpatient and takes a few minutes per eye. In the first hours there may be mild discomfort —a gritty feeling or watering— that soon subsides. Most patients return to work in two or three days and notice progressively sharper vision over the first weeks, always with scheduled check-ups to accompany recovery.
Request an evaluation for laser surgery
If you want to correct myopia, hyperopia or astigmatism and reduce your dependence on glasses, we can assess your case and clearly explain the best option.
Common questions
Frequently asked questions
Is everyone a candidate for the excimer laser?
No. The indication depends on corneal measurements, refractive stability and eye health. The prior evaluation is essential to confirm safety.
When is the improvement in vision noticeable?
It depends on the technique and on each patient’s eye. In general there is progressive improvement in the first days, with stabilization afterwards.
Can laser surgery be related to dry eye?
The ocular surface is always assessed before the procedure. If there is dryness, it can be treated beforehand to improve comfort and results.
When can I return to my routine?
Most patients resume their activities in two or three days, following the team’s instructions. Vision improves progressively from the first 24 to 48 hours.
