Is LASIK Right for You? Complete Candidacy Assessment Guide
Discover if you're a good candidate for LASIK surgery with our comprehensive assessment guide covering age, prescription, health factors, and interactive candidacy evaluation.
LASIK surgery has helped millions achieve clear vision, but it's not suitable for everyone. Understanding whether you're a good candidate is the first step toward making an informed decision about vision correction. This comprehensive guide will help you assess your candidacy and understand what factors determine LASIK eligibility.
Basic Requirements for LASIK
Age 18 or older
CriticalEyes must be fully developed before surgery
The FDA requires patients to be at least 18 for LASIK. However, many surgeons prefer patients to be 21+ as prescriptions are more stable.
Stable prescription for 1+ years
CriticalNo significant changes in vision correction needs
Your prescription should not have changed by more than 0.5 diopters in the past 12 months to ensure lasting results.
Adequate corneal thickness
CriticalSufficient tissue for safe laser reshaping
Minimum corneal thickness of 500 microns is typically required, with at least 250 microns remaining after surgery.
Healthy corneas
CriticalNo corneal diseases or irregularities
Conditions like keratoconus, corneal dystrophies, or significant scarring may disqualify you from LASIK.
Realistic expectations
ImportantUnderstanding of potential outcomes and limitations
LASIK can significantly reduce dependence on glasses but may not achieve perfect vision for everyone.
Good overall eye health
CriticalNo active eye infections or diseases
Conditions like glaucoma, cataracts, or retinal problems may need treatment before considering LASIK.
Age and LASIK Eligibility
18-25 Years
Minimum age met, but prescription stability is crucial. Many surgeons prefer to wait until mid-20s.
*If prescription is stable
25-40 Years
Ideal age range with stable prescriptions and no presbyopia concerns yet.
40+ Years
Still eligible, but presbyopia may require reading glasses regardless of LASIK.
Consider monovision or presbyopia-correcting options
Prescription Requirements
| Condition | Treatable Range | Suitability | Notes |
|---|---|---|---|
| Nearsightedness (Myopia) | -1.00 to -12.00 diopters | Excellent | Most common LASIK correction with high success rates |
| Farsightedness (Hyperopia) | +1.00 to +6.00 diopters | Good | Slightly higher risk of regression compared to myopia |
| Astigmatism | Up to 6.00 diopters | Excellent | Modern LASIK handles astigmatism very effectively |
| Mixed Astigmatism | Varies by case | Good | Requires careful evaluation and advanced techniques |
