Your Personal Guide for Refractive Surgery Day

Everything you need to know, step by step, to regain your visual freedom safely and with confidence.

This guide is for educational purposes. Any surgical decision must be based on a comprehensive medical assessment.

1. Preparation before surgery

Complete this checklist the morning of your surgery.

Contact Lenses

Stop wearing them for the period specified at your consultation; it varies with lens type, wear pattern and corneal measurements.

Morning Hygiene

Take a shower and wash your face thoroughly. Arrive with clean skin.

No Cosmetics

Attend with clean eyelids and no eye makeup, perfume or cologne, following the centre’s preparation instructions.

Comfortable Clothing

Wear a shirt or jacket with buttons or zip (easy to remove without going near your face).

Bring a CompanionRequired

Mandatory. You will not be able to drive after surgery.

2. What Will Happen at the Clinic

A clear step-by-step of your procedure day.

1

Reception

Document signing and preparation.

  • Arrive with clean hands; do not touch your face.
2

Anaesthesia

Anaesthesia is tailored to the technique and clinical circumstances.

  • Anaesthetic eye drops are commonly used. You may notice pressure or touch; tell the clinical team if you feel pain.
  • You will be asked to stare at a fixation light.
3

Surgery

The duration and technology used depend on the selected technique.

  • You will feel light pressure and hear the laser for a few seconds.
  • Stay still and follow the light (the machine does the rest).
4

Discharge

Brief rest, then home with your companion.

  • Keep eyes closed in darkness for the first few hours.
  • Resume screens progressively according to comfort and the instructions for your technique.

3. Key Guidelines During Recovery

Follow these instructions carefully. Your cooperation is essential.

Eye Drop Protocol

You will receive a personalised protocol with antibiotic drops, corticosteroids and artificial tears. The exact schedule may be adjusted slightly depending on how your recovery progresses. Always wash your hands before applying any drops.

Do NOT do these

  • Rub your eyes
  • Apply makeup (1 week)
  • Swim in pools or the sea (at least 2 weeks)
  • Drive on the day of surgery

Recommended

  • Sunglasses outdoors from day 1
  • Artificial tears frequently
  • Use protective shields when sleeping
  • 20-20-20 rule when using screens

Back to Work

With LASIK, you can typically return in a few days; PRK requires more downtime. Avoid physical exertion initially.

Water & Makeup

Avoid swimming pools, the sea, and eye makeup for 1-2 weeks. Be careful when showering.

Screens & The 20-20-20 Rule

When using screens: Every 20 minutes, look 20 feet away for 20 seconds. Use artificial tears frequently.

Sun Protection

Sunglasses are essential outdoors from day 1, especially after PRK, to prevent corneal opacities.

4. Symptoms: Normal vs Urgent

✅ NORMAL & EXPECTED

Attend the planned reviews. Some patients experience:

  • Fluctuating or slightly blurry vision initially.
  • Halos or glare around lights at night.
  • A sensation of "sand" or moderate dry eye.

🚨 CONTACT US IMMEDIATELY

Call us right away if you experience:

  • Severe pain not relieved by your prescribed painkillers.
  • A sudden, sharp decrease or loss of vision.
  • Severe redness, thick discharge, or a very "dirty" eye sensation.

Following the individual postoperative plan and attending reviews helps detect problems early and adjust treatment when needed.

Frequently Asked Questions

Anaesthesia depends on the technique and clinical circumstances. Anaesthetic eye drops are commonly used; you may notice pressure or touch, and you should tell the clinical team if you feel pain.

The clinical team will explain where to look and uses an instrument to keep the eyelids open. Laser platforms include eye-tracking safety systems; if movement is relevant, the surgeon can pause and reposition you.

The time depends on the technique, preparation and postoperative checks. Your centre will tell you how long to allow for the full visit, not only the procedure itself.

Recovery differs by technique and by patient. With LASIK or ICL, improvement is often noticed during the first few days; after PRK, vision is usually more blurred and improves gradually over days to weeks. Final stability and permission to resume activities are assessed at follow-up.

It is often helpful to rest and limit screen use on the first day, following the instructions from your centre. Afterwards, screens can usually be resumed gradually as comfort allows, using prescribed lubrication if indicated.

Grittiness or tearing can occur after some techniques, especially during the first hours or days. Do not rub your eyes, follow the prescribed drops and seek advice if symptoms are intense or worsening.

Medically: you must not drive on the day of surgery. We will confirm at your first follow-up (usually within a few days) that your vision is adequate to drive safely. Legally (Spain): the Highway Code requires waiting approximately one month after refractive surgery (three months for professional drivers) to renew or obtain a licence, submitting a surgical report. The licence is then issued with a maximum one-year validity for the first year. Additionally, if your current licence states you must wear glasses or lenses and you no longer need them after surgery, you must update it at the Jefatura de Tráfico (until you do, the condition on the licence still legally applies).

Office work: 24–48 hours. Light sport: 3–4 days. Contact sport or swimming: you will need to wait at least 2 weeks to avoid impact or infection.

The surgery permanently reshapes the cornea to correct your current prescription. However, the eye is a living organ and presbyopia (reading glasses) will develop naturally with age, a process independent of your myopia or astigmatism correction.
