The optical world has been moving toward individualized/personalized/customized eyewear for the past few years. With the advent of the Izon lenses and Z-view aberrometer and, Zeiss' iScription lenses and now Essilor brings it's new pony to the party with eyecode.
Izon and Zeiss both use an aberrometer to correct higher order aberrations. The Essilor Eyecode claims to calculate the rotational axis of the eye and use this data to manufacture a lens that corrects the lens Rx throughout the entire lens surface by compensating for the change in vertex distance. Although this is novel idea, is it too early? are we too close to marrying both of these technologies to chose one above the other?
In July of 2009, Essilor applied for a manufacturing patent on how to manufacture an ophthalmic lens using photoactive material. This looks like a Essilor already has the technology to develop a lens that corrects higher order aberrations. Only time will tell.
As ECPs we all want the best acuity for our patients and it's obvious that we can achieve this by combining both of these techniques for collecting data to manufacture a better lens for our patients.
