Abstract
Objective To observe the long-term effects and safety of orthokeratology ( Ortho-K,OK) in young my-opia patients.Methods Author enrolled 51 adolescent patients (102 eyes) with myopia who wore OK lens over 2 years period.The average age was 11.63 ±1.91 and the average spherical equivalent refraction was -3.71 ±1.32 diopters ( D) .All patients were fitted with overnight OK for 8~10 hours at night.The visual acuity, refraction, corneal curvature and complications were recorded at pre-wearing, 1 week, 1 month, 3 months, 6 months, 1 year, and 2 years post-wearing. Results Uncorrected visual acuity (UCVA) significantly improved from 0.21 ±0.09 before wearing to 0.99 ±0.10 at 2 years ( P <0.01).Average K value of corneal curvature reduced from 43.27 ±1.16D to 40.69 ±1.30D ( P <0.01). At pre-wearing, 1 year and 2 years, corrected visual acuity ( CVA) was stabilized at 1.0.Spherical equivalent refraction (SER) was -3.71 ±1.32D, -3.74 ±1.33D, and -3.87 ±1.31D respectively.There were no significant changes in CVA and SER (both P >0.05).Average SER increased 0.08D every year.There was no severe complication in the ocu-lar surface.Conclusion Standardized long-term wearing OK is safe and is effective to improve UCVA and control the pro-gression of myopia.关键词
