摘要
目的 探讨准分子激光原位角膜磨镶术(LASIK)用于矫治屈光性角膜切削术(PRK)后欠矫及屈光度回退的效果。方法 2 6例(4 9眼)因PRK术后屈光度欠矫及回退再行LASIK矫治。49眼PRK术前的屈光度为-5 . 5 0D～-10 . 0 0D ,平均(-6 2 5±1 .5 0 )D ,PRK术后欠矫及回退的度数为-2. 2 5D～-5 . 75D ,平均(-3 0±1. 12 )D。观察LASIK矫治术后裸眼视力、屈光度、最佳矫正视力及并发症。术后随访6月以上。结果 裸眼视力≥0 .5者42眼(85. 71% ) ,其中≥1 .0者2 3眼(4 6 .94% )。实际屈光矫正度在预测矫正度的±0. 75以内者为43眼(87 .76% ) ,1眼发生角膜瓣下上皮植入。结论 PRK术后屈光欠矫及回退而残留的近视度数可以用LASIK手术矫治,且疗效好、安全性高,但远期效果尚需进一步观察。
Objective To explore the clinical effect and sec urity of LASIK for correcting the undercorrected and regressive myopia after PRK .Methods 26 patients(49 eyes) were operated by LASIK because of the undercorrected and regressive myopia after PRK. 49 eyes diopters ranged -5.5 0 D to -10.00D, Averaging in (-6.25±1.50)D before PRK;but which ranged -2.25D to - 5.57D,averaging in (-3.0±1.12)D after PRK. After LASIK,the naked vision,the degr ee of diopters,the corrected visual acuity and the complications were observed b y following over 6 months. Results The naked vision ≥1.0 were 46.94%,≥0.5 were 85.71% . Meanwhile there were 84.50% patients' actually corrected diopters being in the r ange of prediced degree ±0.75D. Conclusion The undercorrected and regressed myopia after PRK ca n be corrected by LASIK.
