A Case of Herpetic Keratitis in an Orthokeratology Contact Lens Wearer.

We report a case of herpetic keratitis in an orthokeratology lens wearer. A 17-year-old man who wore an overnight orthokeratology lens for correction of myopia presented to our hospital with pain, lacrimation, and blurred vision affecting the left eye. His corrected visual acuity decreased to 18/20, and he showed dendrites and decreased corneal sensitivity in the left eye.

The prevalence of uncorrected refractive error in Japan: the Locomotive Syndrome and Health Outcome in Aizu Cohort Study.
