Bill Harvey: Before I get old

When we ran our myopia special issue at the end of April, I referred to the two-year results from the Chinese trial looking at the effect of the Essilor Stellest lens on the progression of myopia. These were to be announced at ARVO after we went to press. Just in case they were missed, the team from Wenzhou Medical University confirmed that, not only did those children wearing the highly aspheric (Essilor) lenses full time show a 67% reduction in myopia progression and a 60% slowing of axial length elongation, the results were nearly twice as effective as those found with what they called the ‘slightly aspheric’ lenses. Now, what might they be?
