The article explores the mechanisms of myopia and explores several key areas that need further investigation as to how they might affect optometric practices. Topics covered include the role of higher-order aberrations (HOA) in the development of myopia, the difference in the pathophysiology of several types of myopia, and studies exploring the genetic basis and other factors for myopia development.

The article discusses the global epidemic of myopia, a condition characterized by blurred distance vision. The prevalence of myopia is increasing worldwide, with the highest rates found in Asia-Pacific countries. The development of myopia is influenced by genetic, environmental, and lifestyle factors, with time spent outdoors and near work playing a role in reducing myopia. Myopia is associated with various ocular complications, including cataracts, glaucoma, and myopic macular degeneration, which can lead to vision impairment. The economic burden of myopia is significant, resulting in direct costs and productivity loss. Myopia management therapies, such as spectacle lenses, low-dose atropine, soft peripheral defocus contact lenses, and orthokeratology lenses, should be implemented to combat the consequences of myopia.

There are aspheric gas permeable lenses that operate in the same way as their soft lens counterparts, but a design specific to GP lenses is the translating design. Absolute presbyopes Successful wearers cited convenience as a top priority to continue in contact lenses.[12] Therefore, as practitioners, we should continue to offer contact lenses to our presbyopic patients and troubleshoot as best we can so they are able to remain in lenses for as long as desired. The versatility of multifocal contact lenses is sometimes lost with the addition of new contact lenses every year. [Extracted from the article]

In general, soft lenses are used in milder forms of keratoconus or when the patient is unable to tolerate gas permeable (GP) lenses.5 Lens selection also depends on patient lifestyle and ability to care for the devices. ScCLs are indicated in advanced keratoconus or if the patient has failed with previous lens designs, soft or corne-al gas permeable, due to discomfort, poor fit, or poor vision. The most common type of corneal ectasia, keratoconus presents in adolescence and stabilizes during the third or fourth decade of adulthood.1,2 Patients can suffer mild to severe visual impairment from irregular astigmatism, myopia, vertical coma, or corneal scarring.

The article reports on the prevalence of myopia and factors causing this epidemic. It notes that the rapid increase in prevalence of myopia and consequential risk for pathologic visual conditions like cataracts, glaucoma, and retinal detachment, make myopia a significant concern for today's parents. It adds that myopic child may start to experience greater axial elongation than emmetropes even three years before the actual onset of myopia.
