MCOS Ortho-K Myopia Control Study
- MCOS Ortho-K Myopia Control Study
as many of you know i'm an orthokeratologist and a big fan of ortho-k. if you dont know what i'm talking about, here's a good place to learn about ortho-k:
its not the be-all-and-end-all of vision correction, but it is pretty cool. it may be (probably is?) the only way we have right now of slowing myopia progression in children (the only way that works, that is!)
multiple studies have already shown that ortho-k does make a statistically significant difference in pediatric myopia control. here is the announcement of another such study:"Menicon Company, Ltd. and the Novovision Clinic in Madrid have embarked on a new study, Myopia Control with Orthokeratology Contact Lenses in Spain (MCOS), to compare the axial length growth between white European myopic children wearing orthokeratology contact lenses (OK) and distance single-vision spectacles (SP) over a two-year period. In this prospective, single-center clinical trial, sixty-two subjects 6 to 12 years of age with myopia of -0.75 to -4.00 D and astigmatism < =1.00 D were randomly allocated to wear OK or SP correction. Measurements of axial length (using partial coherence interferometry, Zeiss IOLMaster), anterior chamber depth, corneal topography, cycloplegic refraction and visual acuity are being performed at 6-month intervals. According to information provided by Menicon, the MCOS study offers a number of notable features: a prospective design; well matched samples and high resolution ocular biometry measures, which collectively should elucidate whether OK contact lens wear is a feasible method of myopia control."
