How We Build This Report

Primary Source Collection

Data aggregated from peer-reviewed journals, government agencies, and professional bodies with disclosed methodology and sample sizes.

Editorial Curation

Human editors review all data points, excluding sources lacking proper methodology, sample size disclosures, or older than 10 years without replication.

AI-Powered Verification

Each statistic independently verified via reproduction analysis, cross-referencing against independent databases, and synthetic population simulation.

Human Cross-Check

Final human editorial review of all AI-verified statistics. Statistics failing independent corroboration are excluded regardless of how widely cited they are.

Statistics that could not be independently verified are excluded regardless of how widely cited they are elsewhere.

Economic and Accessibility Factors Interpretation

The average American eyeing LASIK faces a stark financial landscape: they'll likely pay over $2,500 per eye, get little help from insurance, and must navigate a fragmented market where their age, gender, location, and choice of procedure will dramatically alter the price, yet they remain so determined to ditch glasses that three-quarters will bravely sign up for financing to make it happen.

Safety and Complications Interpretation

While the statistics might initially seem like a horror movie script—featuring everything from flap dislocations to ‘suction loss’—modern screening and techniques have turned laser eye surgery into a remarkably safe, predictable, and often life-improving procedure, where most significant risks are now extraordinarily rare and minor annoyances mostly resolve on their own.
