准分子激光原位角膜磨镶术治疗儿童远视性屈光参差

目的 评价准分子激光原位角膜磨镶术(excimer laser in situ keratomileusis,LASIK)治疗儿童远视性屈光参差的疗效.方法 使用美国Summit公司的SVS Apex plus准分子激光系统及Moria公司的微型板层角膜切割系统(LSK),对8例9～14岁远视性屈光参差患者进行LASIK手术,术后进行双眼视训练和系统的弱视治疗.结果 术后裸眼视力和矫正视力明显提高,术前平均最佳矫正视力0.23,术后6个月平均最佳矫正视力0.65;屈光度明显降低,但平均仍残留 2.81D;8例患者全部建立同时视和融合功能,6例有立体视功能.结论 LASIK治疗儿童远视性屈光参差安全有效,可明显提高视力,恢复和建立双眼视功能.

Excimer Laser in situ Keratomileusis for Children''''s Hypermetropic Anisometropia

Objective To evaluate the therapeutic effect of excimer laser in situ keratomileusis(LASIK)for children's hypermetropic anisometropia. Methods A SVS Apex plus excimer laser system of American Summit Company and Moria LSK were used in LASIK.Eight children aged from 9 to 14 years old with hypermetropic anisometropia accepted visual function training and systemic amblyopia therapy after LASIK operation. Results After operation,naked and corrected vision of the patients become better than pre-operation.The pre-operative mean best cor- rected vision was 0.23,and 6 months after operation that was 0.65.The mean ocular diopter reduced obviously,but yet remained 2.81 D.Eight cases established single binocular vision and fusion function,6 cases got stereopsis. Conclusions LASIK for children's hypermetropic anisometropia is safe and effective,it can enhance visual acuity obviously and estab- lish vision function.
