LASIK vs. LASEK: Both Safe, Effective
Vision correction surgery patients will get just as good results from LASIK as LASEK, a new study shows.
Dec. 29, 2006 -- Vision correction surgery patients will get just as good
results from LASIK as from LASEK, a new study shows.
Both surgeries use lasers to cut flaps in the cornea to correct its shape.
LASEK (laser-assisted subepithelial keratectomy) cuts only the outside surface
of the cornea.
This avoids some of the flap problems that can come with the deeper cut made
during LASIK (laser in situ keratomileusis). But LASEK recovery is a bit
longer, and there may be more pain after surgery.
Some doctors say LASEK is better. Others swear by LASIK.
Which is better? To find out, University of Illinois at Chicago researcher
Dimitri Azar, MD, and colleagues compared 122 eyes treated with LASIK to 122
eyes treated with LASEK.
"Both procedures seem safe, effective, and predictable," Azar says
in a news release.
Eyes treated with LASEK ended up with slightly better vision. But the
difference was too small for patients to notice.
"We found that although there were some differences ... that favor the
LASEK procedure, the differences were not clinically significant," Azar
The findings appear in the December issue of the American Journal of
