伴眼球震颤的中高度近视眼准分子激光原位角膜磨镶术的效果

Clinical results of Laser in situ Reratomileusis （LASIK） in 14 myopic patients with congenital nys-tagmus

目的探讨应用准分子激光原位角膜磨镶术（LASIK）治疗伴有先天性眼球震颤的近视的疗效。方法对14例（28眼）伴有眼球震颤的近视施行LASIK治疗，等效球镜度数在-5．00～-12．00D之间，排除角膜炎症，圆锥角膜等眼科疾病。眼球震颤类型：14例均为水平冲动型眼球震颤，眼震值4—8mm，震颤频率2～3次／s，其中轻度代偿头位10例，明显代偿头位4例。结果术后眼球震颤幅度较术前变小，眼震值3～6mm，震动频率1—2次／s；术后的裸眼视力与术前最佳矫正视力差异无统计学意义；术前的平均屈光度为（-5．21±0．48）D，术后1年为（-0．32±0．25）D。结论LASIK治疗伴有眼球震颤的近视疗效确切，安全。

Objective To explore the effectiveness of LASIK for the myopia with congenital nystag-mus. Methods The LASIK for the myopia with nystagmus were performed on 14 patients （28 eyes）. The diopters were -5.00D ～ - 12.00D. All patients were excluded from corneal inflammation, keratoeonus and other eye diseases. All of the 14 patients were horizontal impulsive nystagmus. The nystagmus value was 4 ～ 8 mm, the frequency of the nystagmus were 2 ～ 3 times every second. Ten patients were mild compensatory head -posture, four patients were severe compensatory head-posture. Results After LASIK surgery, the amplitude of nystagmus was smaller than before. The value of nystagmus was 3 ～ 6 mm and the frequency of the nystagmus were 1 ～ 2 times every second. There was no statistical difference between the postoperative naked vision and the preoperative best corrected vision. The average diopter of preoperation was （ -5.21 ± 0.48 ） D. The average diopter of postoperation was （ - 0.32 ± 0.25 ） D after 1 year follow-up. Conclusion LASIK for the myopic patients with nystagmus was precise and safe.
