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

That same 2014 FDA-funded study found up to what share of patients developed new dry-eye symptoms after LASIK?

Accepted Answer

up to 28%. Dry eye is one of the most common LASIK side effects, and for some patients it can persist for months.
