What Does LASIK Involve?
• Patient is given sedative and eye is anesthetized
• Computer-guided scalpel cuts thin layer (flap) of
cornea
• Flap is lifted and moved to the side
• Laser is carefully aligned over cornea

Depends on amount of correction required
With low to moderate myopia
Over 90% achieve 20/40 or better
About 50% achieve 20/20
With high myopia (more then –7D) or high
hyperopia (more than +4D), fewer achieve
20/40 or 20/20
• Complication rate is less than 2% after two
years
Will You Need Glasses After
LASIK?
• Most patients over 40 will need reading
glasses
• Patients who wore bifocals might choose
monovision
