Calhoun Vision's Light Adjustable Lens (LAL): An intraocular lens (IOL) whose optical power can be adjusted with a beam of light after a standard cataract removal and subsequent IOL implantation.

The LAL is an idea that was born out of Dr. Dan Schwartz's (UCSF) vision that an adjustable IOL was needed to solve the pervasive problem seen after many cataract removal and subsequent IOL implantations, in which uncorrected residual refractive errors persist. Dr. Robert Grubbs (Cal Tech, in picture on the right) and his theory of olefin metathesis, for which he won the Nobel Prize in Chemistry in 2005, allowed this idea to become a reality. Because the LAL is made from a unique material, its optical power can be adjusted with the application of light through the redistribution of molecules according to the properties of Dr. Grubbs' theory.


The Codet Vision Group (CVG) has played an important roll in the development of the LAL. Dr. Arturo Chayet has implanted well over 300 LAL's in human eyes and has made several important breakthrough discoveries regarding the LAL, most notably it's ability to create a multifocal effect. Dr. Chayet is currently participating in the LAL's latest FDA trial and hopes to continue to improve the efficacy of the LAL. Additionally, our consulting practice at The CVG is contributing to Calhoun Vision's effort to effectively launch the LAL in the Mexican market.
