All Laser LASIK Eye
Surgery Safer Both Blade and Laser Equally Effective In Treating
Nearsighted Farsighted and Astigmatism
May 6th 2006
The Mayo Clinic reports that femtosecond (bladeless) and mechanical
microkeratome LASIK surgeries produce equal results, using a variety of
eye health measurements. LASIK (Laser-assisted in situ keratomileusis)
involves treating nearsightedness, farsightedness or astigmatism by
reshaping the eye's cornea to alter the way the eye refracts light. The
older traditional method involves using a blade to create a flap, and
then removing a defined amount of corneal tissue by an excimer laser.
Doctors then replace the flap.
The newer technology uses a femtosecond laser to create the flap.
Evidence now shows that this news procedure is just as affective. Dr.
Sanjay Patel said At six months after surgery, there are no differences
between the eyes that had bladeless or microkeratome LASIK with respect
to visual acuity (vision as measured by reading an eye chart), contrast
sensitivity (ability to discriminate bright objects from dark objects),
or in perception of stray light or glare, such as the glare from
oncoming headlights." Sanjay is a Mayo Clinic ophthalmologist and study
