Ortho-K Custom-made CLs Slow Progress of Myopia in Children PDF

Ophthalmology and Optometry
Friday, 27 February 2015

myopia childrenA technique called orthokeratology ("Ortho-K"), using custom-made contact lenses to shape the growing eye, has a significant effect in slowing the progression of myopia (nearsightedness) in children, according to a research review in the March issue of Optometry and Vision Science, official journal of the American Academy of Optometry.

Led by Xing-Rong Wang, MD, of the Affiliated Eye Hospital of Shangdong University of Traditional Chinese Medicine in Jinan, China, the researchers analyzed pooled data from previous studies of Ortho-K. They concluded that orthokeratology does certainly slow myopia progression and retard the axial length growth of the eye. Dr Wang and colleagues analyzed seven previous studies of orthokeratology to treat myopia (nearsightedness) in children. Myopia is one of the most common eye disorders worldwide, with a reported prevalence of 20 to 50 percent in the United States and Europe, and 70 percent or higher in East Asia. Of the seven studies, five were performed in East Asia.

Ortho-K is a relatively new treatment approach, in which the child wears customized contact lenses overnight. Over time, the Ortho-K lenses act to guide eye growth--similar to the use of a dental "retainer" to straighten the teeth. Previous studies have reported encouraging results with Ortho-K in slowing myopia progression.

The seven studies included data on 435 children with mild to moderate myopia, aged six to 16 years. All studies assessed axial length, or the length of the eye from front to back. This is a key measure of eye growth, specifically of interest related to myopia development. The researchers used a method called meta-analysis to pool the study results from the publications they reviewed.

As expected, with or without orthokeratology, axial length increased as the children grew. However, after two years, the increase in axial length was significantly slower in children treated with Ortho-K. The average (weighted mean) difference between groups was about one-fourth of a millimeter. That small but significant change was consistent with the reported effects of Ortho-K in slowing myopia progression. An alternative measure of eye growth (vitreous chamber depth) showed a similar difference between groups.

For reasons that are not yet entirely clear, childhood myopia has increased to epidemic proportions in recent years, especially in Asia. Myopia persists into adulthood and, in the more severe cases, is a risk factor for eye diseases such as cataracts, glaucoma, and retinal detachments.

Eye and vision researchers have been working on new optical treatment approaches to slow myopia progression. Ortho-K is one promising approach; others include contact lens designs that modify the focus on the peripheral retina.

The new review and meta-analysis supports the effectiveness of Ortho-K in producing at least some reduction in the rate of progressive myopia. The questions remain as to the mechanism by which Ortho-K works to control myopic eye growth. Dr Wang and coauthors emphasize the need for additional studies to address this issue, as well as large-scale randomized trials to assess its long-term benefits.

 
RANZCO Warns For Medical Tourism PDF

The Royal Australian and New Zealand College of Ophthalmologists (RANZCO), Australia and New Zealand's peak body for eye care, warns of the dangers of seeking "cheap" or convenient eye operations overseas.

The growing popularity of seeking medical services overseas – or "medical tourism" – raises serious questions around safety standards, patient care, legal recourse and insurance. Some countries promote "package" experiences to lure consumers, such as resort holidays combined with "discounted" medical or cosmetic procedures – sometimes done pool-side. Studies have shown there were more than 10 million medical tourists in 2014 creating an industry worth over $50 billion. Yearly, it is estimated about 25,000 Australians leave the country for cosmetic services.

In eye care, laser and cataract surgery are two of the most commonly-performed operations. They are now being marketed to consumers across the globe as "affordable" health services compared to that available in their own country. Previously the domain of mostly cosmetic procedures, medical tourism has now expanded into more complex surgeries. However, basing a medical decision on cost alone neglects the complexity of diagnosis, treatment, and post-operative care for many eye conditions and diseases.

Laser eye operations, for example, require specific steps pre and post-surgery, including a discussion of the procedure itself and how to recover afterwards. A small percentage of people have unusually thin or irregular corneas and do not qualify for laser surgery at all. The laser eye model varies from country to country, making it difficult for a patient to confirm quality and consistency.

Scarring and contracting antibiotic-resistant infections are just some of the dangers from having surgery performed overseas. If there is clinical negligence, legal recourse may be difficult when dealing with medical professionals and facilities in another country. Additionally, those without private health insurance may be exposed to very expensive bills if an adverse situation occurs.
