Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The high prevalence of myopia - especially in Asian countries - is well documented, as are the sight-threatening complications of high or degenerative myopia. Retinal detachment, glaucoma, vitreal degeneration and focal retinal changes occur secondary to the progressive axial elongation of the eye with age. Specialty rigid lenses have long been shown to lessen this progression in the pediatric population; orthokeratology (ortho-k) lenses are worn at night and change the corneal topography to correct low to moderate amounts of myopia. This same axial elongation has also been shown to occur in young adults with high near demands, however to our knowledge, there are no studies examining the effect of ortho-k lenses in this population. Our project seeks to investigate the efficacy of ortho-k in slowing axial elongation and myopic progression in subjects between the ages of 21-30. Results will help elucidate what role these specialty lenses may have in the management of the myopic patient throughout their development, as well as what potential they have in prevention of associated degenerative changes.
