Clinical study of controlling myopia progression of students wearing orthokeratology

Objective: To observe the clinical effects of wearing orthokeratology lenses to control the myopia progression of students. Methods: 105 cases (10-16 years) from January 2011 to October 2014 with low, moderate myopia were selected, the spherical equivalent was (-3.63 ± 0.95) D. 56 cases (112 eyes) were wearing orthokeratology lenses, 49 cases (98 eyes) were wearing glasses. Both groups were followed up for 2 years to observe the variations of spherical equivalent, axial length, intraocular pressure and corneal thickness. Results: The spherical equivalent changes after two years wearing: the spherical equivalent of the orthokeratology lenses group increased by (-0.47 ± 0.98) D, and that of the glasses group increased by (-1.59 ± 0.91) D; the difference was statistically significant ( p .05). Conclusions: Wearing orthokeratology lenses can effectively delay the progression of myopia and control axial growth. The lenses can be disseminated and used in clinical practice.
