Laser Eye Surgery
Outpatient laser refractive surgery that reshapes the cornea (LASIK flap or SMILE keyhole lenticule) to correct myopia, hyperopia and astigmatism.

Procedure details
How it's performed
Under topical anaesthetic eye drops, an eyelid speculum keeps the eye open. LASIK: a femtosecond laser creates a 90-110 micron corneal flap by tracing a 3D pattern of microbubbles; the flap is lifted, an excimer laser reshapes the underlying stroma to a treatment plan derived from corneal topography, and the flap is replaced. SMILE: a single femtosecond laser sculpts a thin lenticule within the intact cornea, which the surgeon extracts through a 2-4 mm peripheral incision, no flap created. The patient stares at a fixation light throughout.
Preparation
- 1Detailed refraction, corneal topography, pachymetry and dry-eye assessment at least 1-2 weeks before surgery.
- 2Stop wearing soft contact lenses for at least 1 week (longer for rigid lenses) before measurements and treatment.
- 3Avoid eye make-up, perfume and aftershave on the day of surgery.
- 4Arrange transport home as vision will be blurry for several hours.
- 5Receive prescription for post-operative antibiotic and steroid drops.
Recovery
- 1Day 0: Transient blurred vision, mild grittiness and watering for 4-6 hours; wear protective eye shields overnight.
- 2Day 1: Marked improvement in vision; attend the day-1 review with the surgeon.
- 3Days 1-7: Use prescribed antibiotic and steroid drops; avoid swimming, eye rubbing and dusty environments.
- 4Weeks 1-2: Most patients return to driving and office work; mild dry eye is common.
- 5Weeks 2-4: Vision continues to sharpen; resume sport with eye protection.
- 6Months 1-3: Refraction stabilises and lubricant drops are gradually tapered.
Before you travel: what the CDC recommends
The U.S. Centers for Disease Control and Prevention publishes guidance for Americans travelling abroad for medical care. These are its recommendations, not ours.
- Check the qualifications of the clinician who will perform the procedure and the credentials of the facility.
- Bring copies of your medical records, including lab and other test results related to your condition.
- Make sure you can get follow-up care in the United States. Care for complications can be expensive and might not be covered by your health insurance.
- Obtain international travel health insurance that covers medical evacuation back to the United States.
- Plan for the possibility of paying out of pocket for additional or emergency care.
- See your own healthcare provider 4–6 weeks before the trip to discuss risks specific to your health.
- Delay air travel for 10–14 days after major surgery, particularly chest surgery, to reduce risks from changes in cabin pressure.
Laser Eye Surgery abroad: frequently asked questions
How much does laser eye surgery cost in the U.S.?
Typically $3,000 to $10,000, according to All About Vision, 2026.
How long do I need to stay abroad for laser eye surgery?
Plan on about 3 days, from arrival to the flight home. Your surgeon will confirm when it is safe to travel.
Will U.S. insurance pay for laser eye surgery abroad?
Most U.S. health plans do not pay for elective surgery abroad, and cosmetic procedures are not covered at all. The CDC also warns that care for complications after surgery abroad may not be covered, so check your plan before you book.
What the Research Says About LASIK and ReLEx SMILE Laser Eye Surgery
15 peer-reviewed sourcesLaser vision correction has been studied extensively across randomized trials, large cohorts and systematic reviews, and modern femtosecond LASIK and small-incision lenticule extraction (SMILE) consistently deliver high rates of uncorrected vision at or near the patient's target. Comparative analyses report broadly similar visual and refractive accuracy between SMILE, femtosecond LASIK and surface ablation, with differences mainly in higher-order aberrations, corneal biomechanics and early dry-eye symptoms rather than in final acuity. Reported safety profiles are favorable, though the literature is clear that transient dry eye and the need for occasional enhancement are recognized considerations, and careful candidate screening remains essential. Quality-of-life reviews show meaningful gains in daily function and spectacle independence after surgery. The references below span meta-analyses, comparative studies and longer-term outcome data so prospective patients and clinicians can weigh the evidence rather than marketing claims.
