Who Is a Good Candidate for LASIK? Eligibility Tests That Matter

The Right Question
Patients often ask, 'Can I do LASIK?' The clinically correct version is: 'Is LASIK the safest option for my eyes?' Candidacy is decided by anatomy, tear film, power stability, and long-term corneal safety.
Core Eligibility Criteria
- Stable glasses number for at least one year
- Adequate corneal thickness and healthy topography
- No active infection or significant ocular inflammation
- Controlled or minimal dry eye
- No contraindicating retinal or systemic risk factors
Mandatory Pre-LASIK Tests
- Corneal topography/tomography
- Pachymetry for corneal thickness
- Wavefront and refractive analysis
- Tear film and meibomian gland evaluation
- Pupil size assessment in dim light
- Dilated retinal check in moderate/high myopia
Why Contact Lens Users Need Special Planning
Soft and especially rigid contact lenses can temporarily alter corneal shape. Your doctor may ask for a lens-free period before final measurements so treatment planning reflects your true corneal profile.
Who May Be Temporarily Deferred
- Patients with unstable prescription changes
- Patients with active dry eye or lid disease
- Pregnancy/lactation with hormonal refractive fluctuations
- Recent eye infection or inflammation
Who May Need a Different Procedure
If corneal thickness is borderline, topography is suspicious, or power is very high, PRK or ICL may provide better long-term safety than standard LASIK.
Age and Expectations
Age alone does not reject LASIK, but near-vision needs after 40 and early lens changes can influence decision-making. Good counseling about reading vision and future eye changes is part of proper candidacy.
Checklist Before Saying Yes to Surgery
- Understand expected outcomes and limits
- Confirm all diagnostics were done and explained
- Discuss alternatives if you are borderline
- Review post-op follow-up schedule
Conclusion
A good LASIK candidate is defined by safe anatomy and realistic goals, not by marketing promises. For a full eligibility workup, see Lasik Surgery Mumbai and book at Consult.
