Femtolaser Approved for Cataract Surgery

Photonics Spectra
Jul 2012
Illinois-based Abbott’s iFS advanced femtosecond laser has received FDA clearance for use in corneal and cataract surgeries to create bow-shaped or curved arcuate incisions. The fifth generation of IntraLase technology, the iFS laser creates lasik flaps and performs other corneal incisions. The device allows surgeons to make precise, bladeless arcuate incisions and to customize each incision. The placement, length, depth and radius of curvature can influence the surgeon’s desired change to the cornea. These parameters are often difficult to control through traditional incisions using surgical knives.


GLOSSARY
cornea
The transparent front layer of the eye. Light entering the eye is refracted (converged) by the outer surface of the cornea.
femtosecond laser
A type of ultrafast laser that creates a minimal amount of heat-affected zones by having a pulse duration below the picosecond level, making the technology ideal for micromachining, medical device fabrication, scientific research, eye surgery and bioimaging.
