Abstract

PURPOSE
S: To evaluate the efficacy and safety of myopia correction with Ortho-k LK(TM) contact lens lens. METHODS: 20 people who wore Ortho-k LK(TM) Lens from August of 2001 to December of 2001 were prescribed the contact lenses and examined for the degree of myopia correction, the consequences of wearing the lens, the time worn, and any side effects. The examinations were made after putting on the contact lens, 1 day later, 1, 2, 3, 4 weeks later, and 3 months later. The examination was composed of visual acuity, refractive error, keratometry, topography, specular microscope, pachymetry, corneoconjunctival changes using slit-lamp, RESULTS: A single prescription was sufficient for 14 of the 20 contact lens wearers, but 6 people required more than one prescription. Vision correction of over 0.8 was found in over 70% of the cases in the first 24 hours. During the 4-week period, correction of vision over 0.8 was found in 100%. During follow-up period, there were no special changes in the corneoconjunctiva, and the lenses were worn for over 7 hours daily. But the duration of contact lens wear at 3 months decreased to 5.6 hours daily. CONCLUSIONS: The visual outcome of ortho-k Lens were effective and safe. There were few cases with complete compliance to the intended wearing plan and so presents a new problem.
