Review of Optometry:
This review of the COMET study concluded:
"O.D.s should counsel families about risk factors (high accommodative lag/ esophoria at near, low amounts of myopia, two myopic parents) and suggest that PALs may be useful to slow the progression of myopia and prevent the development of high myopia when a child has one or more of these risk factors. For children who do not fall into these categories, PALs do not appear to offer any clinical advantage to slow the progression of myopia vs. SVLs."
In children with these risk factors, myopia progressed between .50 D and .68 D less in three years than the controls when they wore the PALS.
