Evolution in surgical technologies: Goal of increased refractive accuracy.

The article traces the evolution in eye surgical technologies in the U.S. as of December 2014. Topics discussed include the developments in corneal collagen crosslinking (CXL) applications, topography guided-ablations and the introduction of an extended depth-of-focus intraocular lens (IOL), a new drug application that was submitted by Avedro in September for the use of CXL to treat keratoconus and corneal ectasia and the expected launch of topographic-guided excimer laser ablations.
