Lasik facts & stats

Question 1

US LASIK procedure volume fell from about 1.5 million in 2007 to about how many by 2015?

Accepted Answer

about 604,000. The recession, cheaper competing procedures and market saturation all contributed to the decline.

Question 2

A 2008 meta-analysis of over 300 studies found what overall LASIK patient satisfaction rate?

Accepted Answer

95.4%. The review, from the Medical University of South Carolina, combined results across many separate patient surveys.

Question 3

A 2017 study found what share of LASIK patients achieved 20/20 vision without glasses or contacts?

Accepted Answer

62% achieved 20/20 (97% achieved at least 20/40). Most patients end up with very good, though not always perfect, uncorrected vision.

Question 4

An FDA-funded 2014 study found that up to what share of previously symptom-free patients had a new visual symptom (like glare or halos) three months after LASIK?

Accepted Answer

up to 46%. This FDA/NIH/DoD 'LASIK Quality of Life' study pushed the agency to warn that dissatisfaction can affect a meaningful share of patients.
