[目的]探讨准分子激光原位角膜磨镶术(LASIK)治疗屈光不正的预测性、稳定性及安全性。[方法]2004年2月～2009年2月某院收治屈光不正患者6000例(11947眼),其中近视4326例(8627眼),远视1674例(3320眼),行LASIK治疗,术后1月、3月、6月、12月随访复查,考察视力恢复情况。[结果]近视患者术后1年平均裸眼视力及屈光度均显著大于术前,差异有统计学意义(P﹤0.05),低、中、高度近视患者1年后裸眼视力≥1.0百分率分别为89.9%、87.1%和78.1%,而屈光度≤±1.00D的百分率3组分别为84.9%、81.6%和75.4%。远视患者术后平均裸眼近视力及远视力均较术前有显著提高(P﹤0.05),术后1年裸眼远视力≥0.5及≥1.0分别为85.4%和51.3%,术后屈光度显著低于术前(P﹤0.05),术后1年屈光度≤±1.00D的百分率为68.2%。[结论]LASIK治疗近视及远视效果肯定,具有安全、有效及预测性佳、术后稳定性好的优点。
[Objective] To investigate the predictability, stability and safety of refractive ametropia laser in situ keratomileusis (LASIK). [Methods] From February 2004 to February 2009, 6000 cases (11947 eyes) with refractive errors were treated in a hospital, including 4326 myopia (8627 eyes) and 1674 myopia (3320 eyes) underwent LASIK. After operation 1 Month, March, June, December follow-up review, inspection of visual acuity recovery. [Results] The average uncorrected visual acuity and refractive power of 1-year postoperative patients with myopia were significantly higher than those before operation (P <0.05). The percentages of uncorrected visual acuity ≥1.0 years after low, medium and high myopia were 89.9% , 87.1% and 78.1%, respectively. The percentages of diopter ≤ ± 1.00D were 84.9%, 81.6% and 75.4% respectively. The average postoperative naked visual acuity and distance vision of patients with hyperopia were significantly higher than those before operation (P <0.05). One year after the operation, the distance of visual acuity ≥0.5 and ≥1.0 were 85.4% and 51.3% respectively, the postoperative refraction was significantly lower Before operation (P <0.05), the percentage of diopter ≤ ± 1.00D at 1 year after operation was 68.2%. [Conclusion] LASIK is effective in treating myopia and farsightedness, which is safe, effective and predictive and has good postoperative stability.
