everyone who has had elective laser surgery to correct vision in the
United States report their overall satisfaction, according to a
peer-reviewed survey by the American Society of Cataract and Refractive
The procedure, laser-assisted in situ keratomileusis (LASIK) has been
performed 16 million times worldwide, of which about 1 million have
been performed annually in the United States with an overall patient
satisfaction rate of 95.4 percent (2,097 of the 2,198 surveyed).
For an elective surgery like LASIK, satisfaction criteria include
whether the patients’ physical, emotional and financial expectations
are met and physical and psychological benefits achieved.
Researchers, led by MUSC's Storm Eye Institute, looked at whether
patient satisfaction with LASIK has changed over time by comparing
rates for surgeries performed 1995 to 2000 with those performed in and
after 2001. Granted, the procedure has improved by more than a decade
of clinical studies and technological innovation, ASCRS reports.
Meanwhile, the satisfaction of 96 percent was reported in an earlier
study followed by a study showing that 94.6 percent of patients
expressed overall satisfaction.
The survey included a review that analyzed satisfaction rates in
relation to questionnaire characteristics, administration methods and
timing, type of patient refractive error (near- or farsightedness,
astigmatism) and country. All analyses showed very high overall patient
The research team reviewed 19 studies from 13 countries representing
the United States and most industrialized countries worldwide that
surveyed 2,198 patients who had LASIK between 1995 and 2003. A
comprehensive international literature search performed by a Storm Eye
Institute panel had identified 309 peer-reviewed, well-designed studies
of original LASIK surgery, of which 19 reported on both patient quality
of life and satisfaction. All were randomized, controlled clinical
trials or cohort or case-controlled studies.
“This places LASIK among the most successful of all elective surgeries,
comparing very favorably with other elective procedures,” said lead
researcher Kerry D. Solomon, M.D., Magill Vision Center and Storm Eye
Institute. “Because this review process was systematic, transparent,
and based on carefully vetted international and U.S. research, the
findings are highly reliable.”
