LASIK手术矫治屈光参差患者视功能的疗效分析

目的探讨LASIK手术治疗儿童屈光参差的疗效。方法通过回顾性分析30例屈光参差患儿实施LASIK手术前与手术后不同时间视力、屈光度、眼轴、双眼视觉、VEP等视功能参数的变化，了解LASIK手术的疗效。结果近视组手术后裸眼视力有明显提高（P〈0．05），达到了术前最佳矫正视力；屈光度完全矫正；术后三级视功能明显改善。远视组手术后屈光度与三级视功能均有显著改善（P〈0．01），而裸眼视力与矫正视力，视觉诱发电位均无明显改善（P〉0．05）。两组手术前后眼轴无明显增长（P〉0．05）。结论LASIK手术矫治儿童屈光参差，能降低高屈光度眼的屈光力、缩小双眼屈光度的差别，利于双眼融像。

The therapeutic effects analysis on LASIK surgical correction of myopic and hyperopic anisometropia of visual function in patients

Objective To investigate the efficacy of two sets of anisometropic in patients with LASIK surgery. Methods A retrospectively comparative analysis of the LASIK surgery correcting myopia and anisometropic in patients with postoperative visual function changes. Observe high diopter eyes of 15 cases with myopic anisometropia and 15 cases with hyperopic anisometropia after LASIK surgery preoperative and postoperative 1 year, 2 years, 3 years of visual acuity, and check the diopter , axial length, binocular vision, and VEP. Results Myopia uncoIreeted visual acuity was significantly improved （ P 〈 0. 05 ） to the best corrected visual acuity of preoperation. Refractive error is totally corrected. Postoperative three visual function was improved significantly. Hyperopia group diopter with three visual function was improved significantly （P 〈0.01 ）. Visual evoked potentials of both groups were not significantly improved （P 〉 0.05 ）. The axial length of two groups did not significantly increase （ P 〉 0.05 ）. Conclusion LASIK surgery correction of children anisometropia can reduce the refractive power of the high-diopter eye, narrowed eyes diopter difference, which will help the eyes melt.
