Retrospective Review of Corneal changes in overnight Orthokeratology
Wei-Feng Liu MD*, Richard Wu OD#, Xun Shi MD, Guo-Fu Huang MD, Xuan Zhu MD
Orthokeratology (OK) is a clinical technique that uses a reverse- geometry lens designed rigid contact lenses to reshape the cornea to temporarily reduce or eliminate refractive error. Reductions in myopic refractive error of up to 6.00 D can be obtained with this technique. Studies from Hiraoka et al and Cho et al indicate that OK can suppress axial length elongation in childhood myopia. Younger children tend to have faster axial elongation and may benefit from early ortho-k treatment.3 OK is used to control the progression of childhood myopia and the treatment under close monitoring is well accepted by children.

Chronic open angle glaucoma (COAG) or primary open angle glaucoma (POAG) is a chronic and progressive anterior optic neuropathy. It is characterized by a pathological excavation of the optic nerve head and visual field defects that result in deficits perimeter. The disease is associated with damage and destruction of ganglion cell axons. The progressive and irreversible impairment of vision up to blindness is the consequence of this neuronal destruction. As such, glaucoma is the leading cause of irreversible blindness in the world.
