Benefits, clinical facts and potential complications associated with overnight Orthokeratology

Orthokeratology, also known as corneal reshaping, is a clinical technique designed to alter corneal shape, and in terms providing a temporary correction of myopic refractive error. Although there is no direct evidences showing that orthokeratology itself can halt or even reverse the progression of myopia, there are studies indicated that the procedure can suppress axial length elongation in childhood myopia. Despite its low incidence rate, microbial keratitis is a potential complication of overnight orthokeratology that may cause significant visual impairment. In this article, we will focus on the benefits, clinical facts and potential complication such as infectious keratitis associated with orthokeratology.
