Are you considering permanent vision correction but unsure if you qualify? While millions of Americans have successfully achieved visual freedom through LASIK, not everyone is an ideal candidate for this life-changing procedure.
Keep reading to learn more about 6 factors that determine LASIK candidacy.
What is LASIK and How Does It Work?
Before diving into candidacy factors, it’s important to understand how LASIK actually works. LASIK (Laser-Assisted In Situ Keratomileusis) permanently corrects vision by precisely reshaping your cornea, the clear front surface of your eye, allowing light to focus properly on your retina.
During the procedure, your ophthalmologist creates a thin flap in the cornea’s outer layer. This flap is gently folded back, giving your surgeon access to the underlying corneal tissue.
Using an excimer laser, they then remove microscopic amounts of tissue, reshaping the cornea according to your unique prescription. The flap is repositioned and adheres naturally without stitches, acting as a protective bandage during the healing process.
Most patients experience dramatic vision improvements within 24-48 hours, with full stabilization occurring over the following weeks.
What Factors Determine LASIK Candidacy?
1. Age
Age plays a fundamental role in determining LASIK candidacy. This is because younger eyes are still developing, and vision typically stabilizes in early adulthood.
Performing LASIK on an eye that’s still changing could lead to suboptimal long-term results and a potential need for enhancement procedures. While there’s no upper age limit for LASIK, other age-related vision changes like presbyopia (difficulty reading up close) and early cataracts may influence your vision correction options after age 40.
2. Prescription Stability
Ideal LASIK candidates have a consistent prescription for at least 12 consecutive months before surgery. Waiting until your vision stabilizes ensures you’ll enjoy the benefits of LASIK for years to come without requiring additional corrective measures.
3. Corneal Thickness
Adequate corneal thickness is one of the most crucial requirements for LASIK candidacy. During the procedure, your eye surgeon creates a flap in the cornea to reshape the tissue underneath and correct your refractive errors.
Your cornea must have sufficient thickness to maintain its structural integrity after the procedure. Patients with naturally thin corneas may not qualify for traditional LASIK but could benefit from alternative procedures like the EVO ICL.
4. Overall Eye Health
Successful LASIK outcomes require eyes free from significant disease or abnormalities. Several common conditions may affect your candidacy:
- Keratoconus
- Glaucoma
- Cataracts
- Corneal scarring
- Severe dry eye
Your comprehensive eye examination will identify these and other conditions that might influence your LASIK candidacy. Early detection allows your surgeon to recommend appropriate alternatives if LASIK isn’t ideal for your situation.
5. General Health Considerations
Your overall health significantly impacts both your LASIK candidacy and potential outcomes. Certain systemic conditions require special consideration, including autoimmune disorders, diabetes, and pregnancy.
6. Realistic Expectations
Perhaps the most overlooked aspect of LASIK candidacy involves having realistic expectations about what the procedure can and cannot achieve. The ideal LASIK candidate understands:
- While most patients achieve 20/20 vision or better, this outcome cannot be guaranteed
- Some patients may still need reading glasses after age 40 due to presbyopia
- Minor enhancements may sometimes be necessary to achieve optimal results
- Temporary side effects like glare, halos, or dry eye are common during the healing process
A thorough discussion with your LASIK surgeon about expected outcomes based on your specific situation helps ensure you’ll be satisfied with your results.
