Understanding LASIK
LASIK (Laser-Assisted In Situ Keratomileusis) is a popular surgical procedure designed to correct vision problems such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. By reshaping the cornea, LASIK aims to improve the way light is focused on the retina, potentially eliminating the need for glasses or contact lenses.
Vision Prescription Requirements
Your current prescription must be stable for at least one year before considering LASIK. The procedure is most effective for people with:
- Myopia up to -11.00 diopters
- Hyperopia up to +5.00 diopters
- Astigmatism up to 5.00 diopters
Benefits and Success Rates
- Quick Recovery: Most patients experience improved vision within 24-48 hours
- Long-lasting Results: Many enjoy permanent vision correction
- Convenience: Reduces or eliminates the need for corrective eyewear
- High Success Rate: According to the American Refractive Surgery Council, LASIK has a satisfaction rate of over 95%
Candidacy Requirements
Age and Eye Health
- Must be at least 18 years old (many doctors recommend waiting until 21-25)
- Stable prescription for at least one year
- No history of eye diseases
- No significant dry eye syndrome
- Healthy corneas of adequate thickness
- No recent eye infections or injuries
Lifestyle Considerations
Good candidates often:
- Have an active lifestyle
- Play sports
- Work in environments where glasses are impractical
- Travel frequently
Poor candidates may:
- Have careers requiring perfect night vision
- Participate in contact sports
- Have certain autoimmune conditions
- Be pregnant or nursing
Potential Risks and Complications
While LASIK is generally safe, potential complications include:
- Dry Eyes: A common side effect that may be temporary or permanent
- Night Vision Problems: Glare and halos around lights
- Vision Issues: Undercorrection or overcorrection
- Flap Complications: Issues with the corneal flap created during surgery
- Need for Enhancement: Additional procedures may be required

Evaluation Process
Before proceeding with LASIK, a thorough evaluation includes:
- Corneal Thickness Measurement
- Pupil Size Assessment
- Wavefront Analysis
- Complete Eye Examination
Financial Considerations
LASIK is typically considered an elective procedure, with costs ranging from $2,000 to $3,000 per eye. Consider:
- Financing options offered by providers
- FSA/HSA eligibility
- Lifetime cost comparison with glasses/contacts
- Potential need for enhancement procedures
Alternative Options
If LASIK isn't suitable for you, consider these alternatives:
- PRK (Photorefractive Keratectomy): Similar to LASIK but without creating a corneal flap
- SMILE (Small Incision Lenticule Extraction)
- LASEK (Laser Epithelial Keratomileusis)
- ICL (Implantable Contact Lens)
- Modern prescription glasses
- Advanced contact lenses
Making Your Decision
Steps to Take:
- Schedule a comprehensive eye exam
- Consult with multiple LASIK providers
- Research surgeon credentials and experience
- Read patient reviews and testimonials
- Consider timing in relation to work and personal commitments
