Currently, 34% of the world is myopic—approximately 42% of the US population and 80% of some Asian populations.1-3 Projections show that more than 50% of the global population will be myopic by 2050 with one billion at risk of subsequent sight-threatening complications.1-3 In addition to rising numbers, the severity of the condition is also increasing. 

The pathogenesis of myopia is tied to a combination of environmental and genetic factors. Researchers believe myopia progresses due to peripheral hyperopic defocus along the horizontal meridian.4 This defocus stimulates the growth or elongation of the eye. As axial length increases, the risk for myopic macular degeneration, glaucoma, retinal detachment and cataract increase.1,3,5-7 Highly myopic patients (refractive error >-6.00D, axial length >26mm) have an increased risk for visual impairment, as one-third will experience blindness o...
