Safety Profile
FDA Approval and Studies
FDA approved LASIK in 1999
Extensively studied for over 30 years
Millions of procedures performed worldwide annually
Continuously refined with advancing technology
Serious Complications
Extremely Rare (less than 1%):
Infection: <0.1%
Significant vision loss: <0.3%
Flap complications requiring intervention: <0.5%
Dr. Sherif's track record at Dar El Oyoun shows even lower complication rates due to:
State-of-the-art equipment
20+ years surgical experience
Meticulous patient screening
Comprehensive pre-operative testing
Common Side Effects
Temporary (Usually Resolve Within 3-6 Months)
Dry Eyes (Most Common):
Affects 50% of patients initially
Usually mild and temporary
95% resolve within 6 months
Managed with artificial tears
Rare cases may be persistent
Visual Disturbances:
Glare: 30-40% initially, <5% at 6 months
Halos around lights: 25-35% initially, <5% at 6 months
Starbursts: 20-30% initially, <3% at 6 months
Night vision issues: Typically improve over time
Fluctuating Vision:
Common first 1-3 months
Part of normal healing process
Stabilizes as cornea heals
Rare but Possible
Undercorrection/Overcorrection (3-5%):
More common with very high prescriptions
Usually small amounts
Enhancement surgery often resolves
Dr. Sherif offers complimentary enhancements if needed within first year
Regression (2-5%):
Gradual return of some prescription
More common in high myopia
Can occur months to years after surgery
Enhancement may be option
Long-Term Safety
Durability of Results
Studies tracking patients for 10+ years show:
Vision remains stable in 90%+ of patients
Any changes typically minor
Age-related vision changes (presbyopia after 40) are separate from LASIK results
Corneal Integrity
Long-term studies show maintained corneal strength
No increased risk of eye diseases
Normal aging of eyes continues
Annual eye exams still important
Future Medical Procedures
LASIK does not prevent:
Cataract surgery in the future
Treatment for glaucoma, retinal issues
Other eye procedures if needed
Risk Factors
Higher Risk for Complications
Patient Factors:
Very large pupils (>7mm in dark)
Very high prescriptions (>-8.00 or +4.00)
Thin corneas
Irregular corneal shape
Severe dry eyes
Certain autoimmune conditions
Environmental Factors:
Dusty, dirty work environments
Contact sports without eye protection
Poor post-operative care compliance
Dr. Sherif's thorough screening identifies high-risk candidates and may recommend alternative procedures.

Comparing LASIK Safety to Other Procedures
LASIK is safer than:
Long-term contact lens wear (higher infection risk)
Many common elective surgeries
Dental procedures (by many metrics)
Realistic Expectations
Understanding Limitations
LASIK cannot:
Stop normal aging of eyes
Prevent presbyopia (reading vision decline after 40)
Guarantee perfect vision in 100% of cases
Eliminate all need for glasses forever (reading glasses after 40 common)
What LASIK Can Do
Dramatically reduce dependence on glasses/contacts
Improve quality of life
Enable activities difficult with glasses
Provide long-lasting vision correction
Offer excellent safety profile when properly performed
