All Laser LASIK Eye Surgery Safer

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 investigator.
