Contemporary orthokeratology

Contact Lens and Anterior Eye, 2001
Orthokeratology is the temporary reduction or elimination of myopia and astigmatism with rigid contact lenses having a tetra-curve reverse geometry back surface design are currently utilised for this purpose. The essential features of this construction are described. Those clinical characteristics which are favourable, and those which are unfavourable,

Infectious keratitis in orthokeratology

Clinical & Experimental Ophthalmology, 2002
AbstractOrthokeratology 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, 1998
ABSTRACT: Purpose. The 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. Methods.

Chinese Experiences on Orthokeratology

Eye & Contact Lens: Science & Clinical Practice, 2016
The 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, 1998
Summary 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.
