Conclusions:Studies indicate that orthokeratology (ortho-k) is a safe and effective nonsurgical treatment for myopia, particularly in children. This method utilizes specially designed contact lenses to temporarily reshape the cornea, which can help slow the progression of myopia and prevent further axial elongation of the eyeballhown that children who wear ortho-k lenses not only achieve better vision during the day without glasses but also experience a reduction in the rate of myopic progression. This can potentially decrease the risk of developing high levels of myopia later in life, which are associated with serious eye health issues .
Abstract : Overnight orthokeratology is a technique for correcting myopia and is more recently proposed for the prevention of myopic progression. It is potentially an alternative to laser in situ keratomileusis and may be offered to parents whose children are not candidates for refractive surgery and who are searching for an intervention that may lessen or ameliorate developing myopia. In this issue of the Journal, Koffler and Sears present a comprehensive review of overnight orthokeratology. Clinical and theoretical issues remain, however, and this editorial will attempt to add perspective.
Conclusion: The results indicate that the significant improvement in vision-related quality of life and acceptability with OK contact lenses is an incentive to engage in its use for the control of myopia in children.
Conclusions: Toric ortho-k lenses can slow axial elongation effectively in myopic children with moderate-to-high astigmatism. (ClinicalTrials.gov number, NCT00978692.).
SUMMARY Should there be more lecture hours involved in orthokeratology instruction? Today, each school is appropriately educating the students on the basics of orthokeratology with one to two lectures. Of course, not every student will be interested in orthokeratology or myopia control in their practice. What we need to consider is to have more schools offer orthokeratology course electives for those students who have a particular interest in gaining more experience in this type of specialty procedure. It is promising to see that orthokeratology is being instructed in the classroom and being applied clinically at each of the optometry schools/colleges. Ten to 15 years ago, this was a different story. Orthokeratology was not widely accepted and in most schools was not included as part of the curriculum. There has been an evolution from 10 years ago to today, and it is now accepted as more of a viable option of for myopia reduction and, based on current research, myopia control.
Conclusions: The prevalence of myopia in Sherpa children is low and their rural lifestyle appears to be relatively unstressed. Tibetan children have a higher prevalence of myopia and more rigorous schooling. We did not establish a causal relationship between myopia and the type of schooling, or the environment in general, but we did demonstrate that a simple, rural lifestyle is at least compatible with a virtual absence of myopia.
