LASIK Vision Correction

What Is LASIK?

LASIK (Laser-Assisted In Situ Keratomileusis) is a refractive surgery that uses a precision laser to reshape the cornea, allowing light to focus properly on the retina. The result is clear vision without the need for glasses or contact lenses.

Modern LASIK in China uses femtosecond lasers for flap creation and excimer lasers for corneal reshaping, providing exceptional precision and safety. Newer options include SMILE (Small Incision Lenticule Extraction) and ICL (Implantable Collamer Lens) for specific cases.

• Corrects myopia (nearsightedness), hyperopia (farsightedness), and astigmatism
• Procedure takes about 15–30 minutes for both eyes
• Flap created with femtosecond laser (bladeless)
• Cornea reshaped with excimer laser
• Most patients achieve 20/20 vision or better
• Results are permanent, though vision can change with age

What to Expect

LASIK is a quick outpatient procedure with minimal downtime. Most patients notice improved vision within hours.

• Pre-operative assessment: corneal thickness, topography, eye health
• Stop wearing contact lenses 1–2 weeks before assessment
• Procedure takes 15–30 minutes — you are awake but numbed
• Eye drops used for anesthesia — no injections
• Brief recovery period — rest for a few hours after
• Follow-up visits at 1 day, 1 week, 1 month, and 3 months
• Use prescribed eye drops for several weeks

Who Is a Good Candidate?

LASIK candidacy depends on several factors that are evaluated during the pre-operative assessment.

• Age 18+ with stable prescription for at least 1 year
• Myopia up to -10D, hyperopia up to +4D, astigmatism up to 6D
• Adequate corneal thickness for safe treatment
• No active eye diseases (keratoconus, severe dry eye)
• Not pregnant or nursing
• Good general health without autoimmune diseases affecting healing

Benefits of LASIK in China

China has one of the world's largest LASIK markets, with eye hospitals performing enormous volumes of procedures. This experience translates into excellent outcomes.

• Latest-generation laser equipment (femtosecond + excimer)
• Highly experienced surgeons performing thousands of procedures yearly
• Costs 60–80% lower than the US or UK
• Short waiting times — often within days
• Multiple technology options (LASIK, SMILE, ICL) at the same center

Risks & Considerations

LASIK is one of the safest and most satisfying elective surgeries, but it does carry some risks.

• Temporary dry eyes common in first months after surgery
• Night vision issues (halos, glare) usually resolve within weeks
• Rare risk of flap complications or infection
• Results are permanent but presbyopia (reading vision) will develop after 40
• Under-correction or over-correction may require enhancement
• Does not prevent age-related eye conditions (cataracts, macular degeneration)
