Abstract
Purpose: This study was designed to investigate the clinical efficacy, maintaining effect, and safety of orthokeratology lens (Ortho-K LKTM, Lucid Korea, Korea) in children over 12 months.
Methods: Fifty eight eyes of 29 Children were enrolled. Slit lamp examination, uncorrected visual acuity, spherical equivalent and astigmatism, corneal thickness, anterior chamber depth and corneal endothelial cell count were measured before fitting, and 1 week, 2 weeks, 1 month, 3 months, 6 and 12 months after lens fitting. The clinical complications were also checked after lens fitting.
Results: Uncorrected visual acuity was significantly increased to log MAR 0.03 from 0.68 ± 0.11 after 12 months (p = 0.001), and spherical equivalent was decreased to -1.00 ± 0.41 D from -3.06 ± 1.60 diopter (D) during this period (p = 0.013). The mean keratometry was changed from 43.50 ± 1.75 D to 41.90 ± 1.28 D (p = 0.01), and astigmatic values was significantly decreased from 0.46 ± 0.32 D to 0.17 ± 0.06 D (p = 0.013). Also there were no significant changes in corneal thickness, anterior chamber depth and corneal endothelial cell count. We did not find the any other clinical complication relate with Orthokeratology lens.
Conclusions: Orthokeratology lenses seems to be effective to correct visual acuity and safe to maintain fitting OK lens in children.
