Infectious keratitis in orthokeratology
Clinical & Experimental Ophthalmology, 2002AbstractOrthokeratology is a method of changing refraction in myopic patients by using rigid contact lenses to reduce the curvature of the cornea. This treatment was in use in the two cases of corneal ulcer described in this paper and appears to have contributed to the development of their disease.

Corneal Response to Orthokeratology
Optometry and Vision Science, 1998The technique of orthokeratology produces a corneal response to the mechanical pressures exerted by rigid contact lenses. This paper reports a study which investigated the topographic and pachometric corneal changes induced by orthokeratology.Six young myopic subjects (11 eyes) wore "accelerated orthokeratology" lenses (OK-74; Contex Inc., Sherman Oaks,

Chinese Experiences on Orthokeratology
Eye & Contact Lens: Science & Clinical Practice, 2016The prevalence of myopia in Chinese children has been rising each year. Research has shown that orthokeratology is a good method for controlling the progression of myopia. In this article, we review the current prevalence of myopia, the development and management of orthokeratology, and the myopia control methods used in China.

Current trends in modern orthokeratology
Ophthalmic and Physiological Optics, 1998Summary The present article describes the basic concepts and principles of modern orthokeratology. Early investigators postulated a variety of theories. However, controlled clinical studies have shown these methods to be both unpredictable and also modest in their ability to correct myopia.

Myopia and orthokeratology for myopia control
Clinical and Experimental Optometry, 2019The prevalence of myopia in children is increasing worldwide and is viewed as a major public health concern. This increase has driven interest in research into myopia prevention and control in children. Although there is still uncertainty in the risk factors underlying differences in myopia prevalence between ethnic groups, rates in children of East ...

Good clinical practice in orthokeratology
Contact Lens and Anterior Eye, 2008Overnight orthokeratology is becoming more and more popular especially in the Asia-Pacific region where the treatment is primarily used for myopic control in young children. Risk of complications in contact lens wear increases during overnight wear and may further increase when the treatment is used on children.
