SMILE and LASIK eye surgeries stand out as two excellent ways to correct vision that have reshaped the scene for millions worldwide. LASIK boasts a 30-year track record with over 40 million procedures completed globally. SMILE, the newer option, has helped four million patients in the last decade. These treatments give amazing results to people who want to break free from glasses and contact lenses.
The cost of both procedures typically ranges between £2,000 and £3,000 per eye. SMILE surgery costs slightly more upfront at £2,500 to £3,300 per eye. LASIK remains the most popular choice with doctors treating about 800,000 eyes yearly. The biggest difference between them lies in their surgical approach – SMILE uses a keyhole incision while LASIK creates a corneal flap.
This piece helps you learn about everything you need to think over between these procedures. We’ll get into their costs, recovery times, how well they work for different vision problems, and their long-term benefits. This information will help you pick the procedure that fits your needs and lifestyle best.
Understanding the Procedures: SMILE vs LASIK
SMILE and LASIK are amazing advances in vision correction technology that use different surgical approaches. You can choose the right procedure by understanding what makes them different.
What is SMILE eye surgery and how does it work?
Small Incision Lenticule Extraction (SMILE) works as a minimally invasive keyhole procedure under the corneal surface. This breakthrough treatment fixes refractive errors like nearsightedness (myopia) and astigmatism without creating a corneal flap. The surgeon uses a femtosecond laser to create a tiny disc-shaped piece of tissue (lenticule) inside your cornea. This precise laser creates micro-bubbles smaller than 1/1000th of a human hair. A small 3-4mm incision helps remove this lenticule and reshapes your cornea effectively. The procedure takes less than 30 seconds, and the complete surgery lasts about 10-15 minutes.
How LASIK reshapes the cornea using a flap
LASIK (Laser-Assisted In Situ Keratomileusis) remains the most accessible laser vision correction procedure with over 40 million procedures completed worldwide. The procedure combines two different lasers that work one after another. The surgeon first creates a thin hinged flap on your cornea’s surface with a femtosecond laser. They fold back this flap and use an excimer laser to reshape the corneal tissue underneath based on your prescription. The flap goes back in place and heals naturally around its edges within 3-6 hours.
Flap vs. keyhole incision: surgical technique differences
The biggest difference between these procedures lies in how they work. LASIK creates an 18-20mm corneal flap like opening a “door” to reach underlying tissue. SMILE works through a tiny 3-4mm keyhole incision that keeps your cornea’s surface intact. This key difference means SMILE keeps more corneal nerves and anterior stromal tissue safe and might offer better biomechanical stability. The keyhole approach also eliminates problems related to flaps that sometimes happen with LASIK.

Average cost per eye in 2025: SMILE vs LASIK
The price difference between these advanced procedures is still notable. SMILE eye surgery costs range from £2,000 to £3,500 per eye and sits at the premium end of the market. LASIK offers a more budget-friendly option with prices between £1,500 and £3,000 per eye. Some providers offer treatment from £1,429. The price gap shows the newer technology used in SMILE procedures.
What’s included in the price? Pre-op, surgery, aftercare
The quoted prices usually cover the entire treatment experience. Reputable clinics include pre-operative consultations, the procedure, and follow-up appointments. The detailed aftercare packages often include medication, dedicated helpline access, and post-operative check-ups for up to 12 months. You should confirm what your quote covers before committing—especially for potential enhancement procedures.
Why SMILE may cost more upfront but less long-term
SMILE might offer better value over time despite higher costs upfront. The premium price reflects advanced femtosecond laser technology used, which costs approximately £1-2 million. The faster recovery time of 3-4 days means less time away from work. All the same, SMILE’s reduced risk of complications compared to flap-based procedures could eliminate unexpected medical expenses.
Financing options and payment plans available
Many flexible payment solutions make these procedures available to more people. Clinics offer interest-free financing for 6-24 months, and monthly payments start from £41 per eye. Extended plans at around 14.9% APR help spread costs over longer periods. These options let you get improved vision right away while managing your budget.
Recovery and Aftercare: Time, Comfort, and Risks
Recovery experiences after laser eye surgery are different from one procedure to another. The healing trip is a vital consideration when you think over your options.
SMILE vs LASIK recovery time: what to expect
These procedures have distinct recovery patterns. SMILE patients see their vision improve right away. Full visual recovery happens in 3-4 days. Vision becomes stable over a few weeks to a month. Most patients can get back to their normal activities within a week. LASIK gives quick original improvement—usually within 24 hours. Complete stability takes 3-6 months because corneal nerves need time to regenerate after creating the flap.
Dry eye risk: SMILE’s advantage in nerve preservation
Almost 95% of patients experience dry eye symptoms right after LASIK. SMILE reduces this risk by a lot through its keyhole approach that keeps more corneal nerves intact. Research shows SMILE patients’ nerves regenerate faster. They need fewer lubricating eye drops after surgery.
Return to work and sports: timeline comparison
Patients can typically return to:
- Office work: 1-3 days for both procedures
- Light exercise: 24 hours after surgery
- Swimming: 1 week for SMILE; 2 weeks for LASIK
- Contact sports: 6 weeks for SMILE; LASIK might not be suitable
Post-op care and follow-up at Precision Vision London
Precision Vision London’s aftercare programme runs for 12 months. Patients come back for check-ups after one day, 3-4 weeks, 3 months, and 12 months. This well-laid-out approach will give a smooth healing process. The team addresses concerns quickly and includes touch-up procedures if needed.
Long-Term Value and Suitability
Your individual needs and lifestyle will determine which procedure gives you better long-term value.
Who benefits more from SMILE? (e.g. contact sports, dry eyes)
SMILE surgery works best for athletes and active people. The procedure keeps corneas 47% stronger than LASIK, making it perfect for anyone who plays contact sports. Research shows SMILE keeps more anterior corneal tissue intact and causes minimal changes to corneal structure. Patients who already have dry eyes also do better with SMILE. The procedure disrupts fewer nerves, and clinical studies show much fewer dry eye symptoms compared to LASIK 6 months after surgery.
LASIK’s broader treatment range: myopia, hyperopia, astigmatism
LASIK can correct a wider range of vision problems. SMILE treats myopia up to -10.0D with astigmatism up to 3.0D. LASIK goes further – it corrects myopia up to -12.0D, hyperopia up to +6.0D, and astigmatism up to 6.0D. Right now, SMILE can’t treat hyperopic or mixed astigmatism prescriptions.
Enhancement rates and retreatment needs
Both procedures rarely need enhancements. Studies reveal enhancement rates of 2.1% after one year and 2.9% after two years with SMILE. People over 35 have higher risks (odds ratio: 5.6), along with those who need stronger prescriptions. Retreatment options differ between the two. LASIK lets surgeons simply lift the flap, while SMILE needs different approaches.
Patient satisfaction and visual outcomes in UK studies
Long-term results look similar for both procedures. Three years after surgery, 90% of SMILE patients had 20/20 vision or better, while LASIK achieved 85%. Patient satisfaction stays high for both – over 90% of patients report being happy six months after their procedure.
